Stem Cell Stories That Caught our Eye: Making blood and muscle from stem cells and helping students realize their “pluripotential”

Stem cells offer new drug for blood diseases. A new treatment for blood disorders might be in the works thanks to a stem cell-based study out of Harvard Medical School and Boston Children’s hospital. Their study was published in the journal Science Translational Medicine.

The teams made induced pluripotent stem cells (iPSCs) from the skin of patients with a rare blood disorder called Diamond-Blackfan anemia (DBA) – a bone marrow disease that prevents new blood cells from forming. iPSCs from DBA patients were then specialized into blood progenitor cells, the precursors to blood cells. However, these precursor cells were incapable of forming red blood cells in a dish like normal precursors do.

The blood progenitor cells from DBA patients were then used to screen a library of compounds to identify drugs that could get the DBA progenitor cells to develop into red blood cells. They found a compound called SMER28 that had this very effect on progenitor cells in a dish. When the compound was tested in zebrafish and mouse models of DBA, the researchers observed an increase in red blood cell production and a reduction of anemia symptoms.

Getting pluripotent stem cells like iPSCs to turn into blood progenitor cells and expand these cells into a population large enough for drug screening has not been an easy task for stem cell researchers.

Co-first author on the study, Sergei Doulatov, explained in a press release, “iPS cells have been hard to instruct when it comes to making blood. This is the first time iPS cells have been used to identify a drug to treat a blood disorder.”

In the future, the researchers will pursue the questions of why and how SMER28 boosts red blood cell generation. Further work will be done to determine whether this drug will be a useful treatment for DBA patients and other blood disorders.

 

Students realize their “pluripotential”. In last week’s stem cell stories, I gave a preview about an exciting stem cell “Day of Discovery” hosted by USC Stem Cell in southern California. The event happened this past Saturday. Over 500 local middle and high school students attended the event and participated in lab tours, poster sessions, and a career resource fair. Throughout the day, they were engaged by scientists and educators about stem cell science through interactive games, including the stem cell edition of Family Feud and a stem cell smartphone videogame developed by USC graduate students.

In a USC press release, Rohit Varma, dean of the Keck School of Medicine of USC, emphasized the importance of exposing young students to research and scientific careers.

“It was a true joy to welcome the middle and high school students from our neighboring communities in Boyle Heights, El Sereno, Lincoln Heights, the San Gabriel Valley and throughout Los Angeles. This bright young generation brings tremendous potential to their future pursuits in biotechnology and beyond.”

Maria Elena Kennedy, a consultant to the Bassett Unified School District, added, “The exposure to the Keck School of Medicine of USC is invaluable for the students. Our students come from a Title I School District, and they don’t often have the opportunity to come to a campus like the Keck School of Medicine.”

The day was a huge success with students posting photos of their experiences on social media and enthusiastically writing messages like “stem cells are our future” and “USC is my goal”. One high school student acknowledged the opportunity that this day offers to students, “California currently has biotechnology as the biggest growing sector. Right now, it’s really important that students are visiting labs and learning more about the industry, so they can potentially see where they’re going with their lives and careers.”

New stem cell recipes for making muscle: new inroads to study muscular dystrophy (Todd Dubnicoff)

Embryonic stem cells are amazing because scientists can change or specialize them into virtually any cell type. But it’s a lot easier said than done. Researchers essentially need to mimic the process of embryo development in a petri dish by adding the right combination of factors to the stem cells in just the right order at just the right time to obtain a desired type of cell.

Making human muscle tissue from embryonic stem cells has proven to be a challenge. The development of muscle, as well as cartilage and bone, are well characterized and known to form from an embryonic structure called a somite. Researches have even been successful working out the conditions for making somites from animal stem cells. But those recipes didn’t work well with human stem cells.

Now, a team of researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA has overcome this roadblock by carrying out a systematic approach using human tissue. As described in Cell Reports, the scientists isolated somites from early human embryos and studied their gene activity. By comparing somites that were just beginning to emerge with fully formed somites, the researchers pinpointed differences in gene activity patterns. With this data in hand, the team added factors to the cells that were known to affect the activity of those genes. Through some trial and error, they produced a recipe – different than those used in animal cells – that could convert 90 percent of the human stem cells into somites in only four days. Those somites could then readily transform into muscle or bone or cartilage.

This new method for making human muscle will be critical for the lab’s goal to develop therapies for Duchenne muscular dystrophy, an incurable muscle wasting disease that strikes young boys and is usually fatal by their 20’s.

The new protocol turned 90 percent of human pluripotent stem cells into somite cells in just four days; those somite cells then generated (left to right) cartilage, bone and muscle cells.  Image: April Pyle Lab/UCLA

Results are in: The Winners of our 2017 #StemCellResolution Campaign

We asked and you answered! In January, we launched our first Stem Cell Resolution campaign to raise awareness about the importance of stem cell research. We challenged scientists, students, institutes and the public to make a #StemCellResolution and share it on social media.

The goal of our campaign was to start a larger conversation about why stem cell research is important not just to advance science but to develop cures for diseases that currently have none.

Our campaign ran for the month of January, and we had global participation on multiple social media platforms including Twitter, Instagram, videos and blogs. Some resolutions involved answering important research questions while others involved empowering the public to pursue and understand scientific evidence to make their own informed decisions about the benefits of stem cell treatments for treating disease.

I was thoroughly impressed with everyone’s enthusiasm towards supporting and sharing this campaign that I plan to hold it again next year. But for now, I’ll announce the winners of our 2017 #StemCellResolution campaign. We picked the most inspiring resolution for each social media category and a few honorable mentions. The winner of each category will receive CIRM Stem Cell Champions t-shirts.

Winner: Pedro Soria Jr. (@shadowtype)

Pedro is a former CIRM Bridges student who is conducting stem cell research in neural regeneration at Western University in Southern California.

My Stem Cell Resolution for 2017 is to create a social media page dedicated to educating, enlightening and disseminating information about past, current, and future stem cell related studies to the general public, as well as those in science, in order to bring to light the importance of stem cell research. My objective is to bring people together regardless of whether or not they Originate from the natural sciences and spark an interest in this emerging field. Coming from a family where I'm first generation Mexican American and the only scientist has shown me the importance of communication amongst those that have little knowledge of the natural world especially people that come from countries that aren't scientifically advanced. Both my parents are born and raised in Michoacan, Mexico, in a small mountain town called Ario de Rosales. Back in my parents day, most people were farmers that worked from sun rise to sunset in order to feed and provide for their families. Naturally, they had little time for education because of the need to survive but had a positive work ethic, which I was lucky to inherit. My parents came to America for an opportunity to improve their situations and provide for themselves and families back home. They worked so hard to obtain what they have and to give me the chance they never had, which I'm so deeply grateful for each and every day of my life!! I had always felt destined for more than mediocre and enjoy taking on challenges to improve myself mentally, physically and spiritually. As a stem cell scientist, it is my responsibility to share my knowledge with everyone I encounter in order to bring change to this world. I wouldn't be where I am if it weren't for the support of my family, friends, professors, colleagues and of course #CIRM . Please join me on this journey and spread the word to anyone that will listen because we're all on this ride together in one way or another. That is my #stemcellresolution #soriaclan #bringingchange #cellculture Look out for my social media page #cellculture for all your stem cell info and check out the @cirm_stemcells to see what this beautiful institute is doing this year!!! #StemCellResolution

 An excerpt from Soph’s blog is below. I highly recommend reading the entire piece as it is very engaging and inspiring!

“For my Stem Cell Resolution – I couldn’t decide on one, so instead, I’ve made 4! Oops!

First, I want to raise awareness that stem cell biology is as important as stem cell treatments! There is lots of hype over stem cell treatments across the globe, but I want to stress that there are only a handful that have actually been approved! I could very well be biased as I’m studying stem cells and their biological mechanisms that exist normally in our bodies – but I want to stress the importance of this work. Simple biology – as I think it will hold the key to all the future stem cell medicine! Once we know how stem cells work in our bodies we can exploit that to make the treatments, or even learn more about our normal development!

 Honorable Mention: Stacey Johnson (@msstaceyerin)

Stacey is the Director of Communications and Marketing for CCRM, the Centre for Commercialization of Regenerative Medicine in Canada. She also is a regular contributor to CCRM’s Signals Blog.

“Since I’m not a scientist, a student or a patient, but I regularly communicate about stem cells to raise awareness and educate the public, my #stemcellresolution is to use this forum to spread the news – what I do best – about this fun and important challenge.”

 Thank you and see you next year!

Science communications is a vital tool that scientists and science enthusiasts need to leverage now more than ever to support stem cell research. Speaking out through social media or blogs is a great way to do this, and I want to congratulate all those that participated this year. I’m grateful for your support!

We look forward to doing this again next year and this time, you’ll have an entire year to ponder your next #StemCellResolution.

Discovering stem cells and science at Discovery Day

discoveryday

The CIRM booth at Discovery Day at AT&T Park

Someone stole my thigh bone. One minute it was there. The next, gone. I have narrowed down the list of suspects to the more than 25,000 people attending Discovery Day at San Francisco’s AT&T Park.

To be honest, the bone was just a laminated image of a bone, stuck to the image of a person drawn on a white board. We were using it, along with laminated images of a brain, liver, stomach and other organs and tissues, to show that there are many different kinds of stem cells in the body, and they all have different potential uses.

The white board and its body parts were gimmicks that we used to get kids to come up to the CIRM booth and ask what we were doing. Then, as they played with the images, and tried to guess which stem cells went where, we talked to their parents about stem cell research, and CIRM and the progress being made.

discoveryday-karen

We also used Play Doh so that the kids could model cell division and specialization during embryonic development. But mostly it was so the kids could play with the Play Doh while we talked to their parents.

It is shameless I know but when you are competing against more than 130 other booths for people’s attention – and some of these booths had live snakes, virtual reality devices, or they just let kids throw and hit things – you have to be creative.

And creativity was certainly the key word, because Discovery Day – part of the annual week-long Bay Area Science Fair – was filled with booths from companies and academic institutions promoting every imaginable aspect of science.

So why were we there? Well, first, education has been an important part of CIRM’s mission ever since we were created. Second, we’re a state agency that gets public funding so we feel we owe it to the public to explain how their money is being used. And third, it’s just a lot of fun.

NASA was there, talking about exploring deep space. And there were booths focused on exploring the oceans, and saving them from pollution and over-fishing. You could learn about mathematics and engineering by building wacky-looking paper airplanes that flew long distances, or you could just sit in the cockpit of a fighter jet.

discoveryday-victor

And everywhere you looked were families, with kids running up to the different booths to see what was there. All they needed was a little draw to get them to stick around for a few minutes, so you could talk to them and explain to them what stem cells are and why they are so amazing. Some of the kids were fascinated and wanted to know more: some just wanted to use the Play Doh;  at least one just wanted to eat the Play Doh, but fortunately we were able to stop that happening.

It was an amazing sight to see a baseball stadium filled with tens of thousands of people, all there to learn about science. At a time when we are told that kids don’t care about science, that they don’t like math, this was the perfect response. All you had to do was look around and see that kids were fascinated by science. They were hungry to learn how pouring carbon dioxide on a candle puts out the flame. They delighted in touching an otter pelt and feeling how silky smooth it is, and then looking at the pelt under a microscope to see just how extraordinarily dense the hairs are and how that helps waterproof the otter.

And so yes, we used Play Doh and a white board person to lure the kids to us. But it worked.

There was another booth where they had a couple of the San Francisco 49er’s cheerleaders in full uniform. I don’t actually know what that had to do with teaching science but it was very popular with some of the men. Maybe next year I could try dressing up like that. It would certainly draw a crowd.


Check us out on Instagram to learn more about CIRM’s educational outreach efforts.

We had a lot of fun this weekend teaching young minds about what stem cells are and where they are located in the human body at the @bayareascience #DiscoveryDay festival. We had one activity where kids learned about embryonic stem cells and development using playdoh and another white board activity about adult stem cells. Students learned that each organ has its own set of adult stem cells that can regenerate lost or damaged cells in that specific organ. It was really fun to explain to kids and their parents why stem cells and regenerative medicine research are important. • • • #BASF2016 #stemcells #stemcellresearch #stemeducation #STEM #teaching #education #research #attpark #CIRM #development #embryonicstemcells

Investing in student researchers now for future stem cell therapy homeruns

Even though my San Francisco Giants didn’t make it to the World Series this year, I still watched Game 1 two nights ago between the Cleveland Indians and the Chicago Cubs. As each batter stepped up to the plate for their first at bat, I thought about all the years of training and in-game experience it must have required for each athlete to reach this pinnacle of their profession. That training certainly relied on mentoring from great coaches and early financial support in the form of athletic scholarships, etc. Without that help, you could argue that the number of young, high-caliber baseball players would dwindle over the generations and the sport eventually would lose relevance.

The CIRM Bridges Program: training the next generation of all-star stem cell researchers, like Eliana Ochoa-Bolton (pictured here)

I think the same can be said for stem cell research. The field is currently chock-full of veteran, superstar scientists who are leading the charge of bringing first-of-their-kind stem cell treatments to clinical trials (for example, check out Monday’s exciting blog). But the field is still in its infancy and will require a well-trained workforce of scientists, physicians and technicians throughout the 21st century and beyond to fully realize and implement the potential of stem cells to treat patients with unmet medical needs. But cuts in federal funding for research mean this is a particularly challenging time to get started on a scientific career, especially for economically disadvantaged students.

That’s where the Bridges to Stem Cell Research and Therapy Awards Program comes into the picture. Started in 2009, the program provides paid stem cell research internships to students at universities and colleges that don’t have major stem cell research programs. Each Bridges internship includes thorough hands-on training and education in stem cell research, and direct patient engagement and outreach activities that engage California’s diverse communities.

Earlier this year, the CIRM governing Board re-upped on their investment in the Bridges Program to the tune of $40 million. Each of the fourteen awarded schools will have enough funding to support up to ten trainees per year for up to five years. The program has become a source of pride for the CIRM team as well as for each campus. Case in point, this past Wednesday the news center at California State University, Northridge (CSUN) featured a story about the school’s new $2.77 million Bridges grant. Professor Cindy Malone, CSUN’s Bridges Program Director, looked back at the accomplishments from their previous round of funding which began in 2009:

“When we first launched the [CSUN-UCLA Bridges to Stem Cell Research Program], we didn’t know how successful it would become. Our students are taking part in cutting-edge research alongside some of the greatest minds in stem cell research. They are presenting papers at some of the top professional conferences in the world. When they graduate, they are highly sought after by the top medical and graduate schools in the country, and rightly so.”

Eliana Ochoa-Bolton

One of those students is Eliana Ochoa-Bolton who spent much of her senior year at CSUN as a Bridges intern in the laboratory of Samantha Butler at UCLA. There, she contributed to the lab’s efforts to better understand the nerve signals that become damaged in spinal cord injury with the hope of eventually restoring them. Ochoa-Bolton, who is now a CSUN master’s student in biology and aspires to earn a doctorate, is very grateful for her Bridges experience: “It was such an amazing opportunity. I got to do work I didn’t think possible as an undergraduate.”

Now embarking on the second round of Bridges funding, Malone mapped out the plan for the program’s next five years:

“We will continue to partner with UCLA as our internship-host institution. There, our students will perform 10 months of intensive stem cell research. New research training courses will be launched in the next year to prepare our undergraduates for the new Stem Cell Scientist Training Program and for the increasingly technical job market in California.”

For us CIRM team members and the CIRM governing Board, the Bridges program and its high school counterpart, the CIRM Spark program, continue to be among our favorite awards because we’re continually amazed how much the student’s learn and we’re inspired by their unbounded enthusiasm for stem cell research.

It makes me very optimistic that these students are destined to hit some future stem cell treatments home runs.

Celebrating Stem Cell Awareness Day with SUPER CELLS!

scad_logo_2016

To all you stem cell lovers out there, today is your day! The second Wednesday of October is Stem Cell Awareness Day (SCAD), which brings together organizations and individuals that are working to ensure the general public realizes the benefits of stem cell research.

For patients in desperate need of treatments for diseases without cures, this is also a day to recognize their struggles and the scientific advances in the stem cell field that are bringing us closer to helping these patients.

How are people celebrating SCAD?

This year, a number of institutes in California are hosting events in honor of Stem Cell Awareness Day. Members of the CIRM team will be speaking on Saturday about “The Power of Stem Cells” at the Buck Institute for Research on Aging in Novato (RSVP on Facebook) and at the Berkeley Student Society for Stem Cell Research Conference in Berkeley (RSVP on Eventbrite). There are also a few SCAD events going on this week in Southern California. You can learn more about these all events on our website.

You can also find out about other SCAD celebrations and events on social media by following the hashtag #StemCellAwarenessDay and #StemCellDay on Twitter.

Super Cells: The Power of Stem Cells

Super Cells exhibit at the Lawrence Hall of Science

Super Cells exhibit at the Lawrence Hall of Science

Today, the CIRM Stem Cellar is celebrating SCAD by sharing our recent visit to the Lawrence Hall of Science, which is currently hosting an exhibit called “Super Cells: The Power of Stem Cells”.

This is a REALLY COOL interactive exhibit that explains what stem cells are, what they do, and how we can harness their power to treat disease and injury. CIRM was one of the partners that helped create this exhibit, so we were especially excited to see it in person.

Super Cells has four “high-tech interactive zones and a comprehensive educational guide for school children ages 6-14”. You can read more details about the exhibit in this promotional handout. Based on my visit to the exhibit, I can easily say­­ that Super Cells will be interesting and informative to any age group.

The exhibit was unveiled on September 28th, and the Hall told us that they have already heard positive reviews from their visitors. We had the opportunity to talk further with Susan Gregory, the Deputy Director of the Hall, and Adam Frost, a marketing specialist, about the Super Cells exhibit. We asked them a few questions and will share their interview below followed by a few fun pictures we took of the exhibit.


Q: Why did the Lawrence Hall of Science decide to host the Super Cells exhibit?

The Lawrence Hall of Science has a history of bringing in exciting and engaging traveling exhibitions, and we were looking for something new to excite our visitors in the Fall season. When the opportunity presented itself to host Super Cells, we thought it would be a good fit for our audience. Additionally, the Hall is increasing its programming and exhibits in the fields of biology, chemistry and bioengineering.

Q: What aspects of the Super Cells exhibit do you think are valuable to younger kids?

We strive to make our exhibit experiences hands-on and interactive. The Hall believes that the best way for kids to learn science is for them to be active in their learning. Super Cells offers a variety of elements that speak to our philosophy of learning and make learning science more fun.

Q: How is exhibit similar or unique to other exhibits you’ve hosted previously?

 The Hall hosts and develops exhibits across a broad range of scientific, engineering, technology and mathematical topics. We are always looking for exhibits that address recent scientific advances, and also try to showcase cutting edge research.

Super Cells presents both basic cell biology and information about recent medical and scientific advances, so it fits. Also, as mentioned in our behind the scenes story about the exhibit install, in the past many of our traveling exhibits were very large experiences that tended to take up a lot of space on the museum floor. One thing that is great about Super Cells is that it packs a lot of information into a relatively small space, allowing us to keep a number of experiences and activities that our audience has come to love on the floor, instead of removing them to make room.

Q: Will there be any special events at the Hall featuring this exhibit?

On November 11, the Hall will host a fun day of activities centered around DNA and the exhibit. Younger visitors will make DNA bracelets based on the unique traits in their genome, while older kids will isolate their own DNA using a swab from inside their cheek. We are still finalizing the details of this event, but it will definitely happen.

Q:  Why do you think it’s important for younger students and the general public to learn about stem cells and stem cell research?

As UC Berkeley’s public science center, the Hall is committed to providing a window into cutting edge research and the latest scientific information. We think it’s really important for people and kids to learn about the skills and science behind current research so they can be prepared for a future of incredible scientific challenges and opportunities that we can’t foresee.


Super Cells will be open at the Lawrence Hall of Science until November 27th, so be sure to check it out before then. If you don’t live in California, don’t worry, Super Cells will be traveling around the U.S., Europe and Canada. You can find out where Super Cells is touring next on their website.

We hope you enjoy our photos of the Super Cells exhibit!

Science and Improv: Spotlight on CIRM Bridges Scholar Jill Tsai

As part of our CIRM scholar series, we’re featuring the research and career accomplishments of CIRM funded students.

What do science and improv have in common? The answer is not a whole lot. However, I recently met a talented student from our CIRM Bridges master’s program who one day is going to change this.

Jill Tsai

Jill Tsai, CIRM Bridges scholar

Meet Jill Tsai. She recently graduated from the CIRM Bridges program at the Scripps Research Institute in San Diego and is now starting a PhD program in cancer biology at the City of Hope in Duarte California.

Jill received her Bachelors from UC Merced general biology and went to Cal Poly Pomona for a Master’s program in cancer research. While at Cal Poly Pomona, she successfully applied for a CIRM Bridges internship that allowed her to finish her Master’s degree at Scripps in the lab of Dr. Lazzerini Denchi.

I met Jill at the 2016 Bridges Conference in July and was immediately impressed by her passion for science and communications. I was also intrigued by her interest in improv and how she balances her time between two very different passions. I’m thrilled that Jill agreed to an interview for the Stem Cellar as I think it’s valuable to read about scientists who are pursuing multiple passions not necessarily related to science.

Enjoy!

Q: What did you study during your Bridges internship?

JT: I was a research intern in the lab of Dr. Lazzerini Denchi. In his lab, we study telomeres, which are the pieces of DNA at the end of chromosomes that help protect them from being degraded. We’re specifically looking at proteins that help maintain telomere function in mouse stem cells. We do big protein pull downs to try to figure out what new and novel proteins are surrounding the mechanisms that maintain telomere function, and then we do functional assays to figure out what these proteins do.

Lazzerini Denchi’s lab focuses on basic research and how certain proteins affect telomere length and also the telomere deprotection response. One function of telomeres is that they suppress the double and single stranded DNA repair mechanism. If you don’t suppress those mechanisms, then the ends of those linear chromosomes look exactly like double stranded DNA breaks and repair proteins try to fix them by fusing those chromosomes together.

There are great pictures from Lazzerini Denchi’s first author publication showing chromosomes hooked end to end to end like long strings of spaghetti as a result of telomere deprotection. We are studying novel proteins that assist telomeres with the deprotection response and determining whether these proteins have some other kind of function as well.

Our larger focus in the lab is being able to understand cancer and specific telomere related genetic disorders that are associated with cancer.

Q: What was your CIRM Bridges experience like?

JT: CIRM was really amazing, and I credit it a lot for being able to start a PhD this fall. I’d been working in my lab at Cal Poly Pomona for five years, and my research unfortunately wasn’t working out. I was probably going to have to quit the program or take an out with an easier project. When I applied to CIRM, I was hoping to get the internship because if I didn’t get it, I was going to go down a completely different career path.

The CIRM internship was very valuable to me. It provided training through stem cell classes and lectures and allowed me to immerse myself in a real lab that had real equipment and personnel. The experience took my research knowledge to the next level and then some. And I knew for sure it had when I was at the poster session during the Bridges conference. I was walking around and asking students about their research, and I understood clearly the path of their research. I knew what questions were good to ask and what the graphs meant without having to take them home and dissect them. It was extremely satisfying to be able to understand other’s scientific research by just listening to them.

I am so excited to start my PhD in the fall. For the first time, I feel confident about my foundational biology and research skills. I also have a better understanding of myself and where I need to improve in comprehension and technique. I am ready to jump into grad school and improve as a scientist.

Q: What are your future career steps?

JT: I want to do something that involves teaching or being able to educate people. I’ve worked as a TA in my master’s program for a few years, and I really enjoy that experience of clarifying complex subjects for people. But to be honest, I also don’t know what I want to do right now so I’m keeping my options open.

Q: What’s your favorite thing about being scientist?

JT: Being a scientist forces you to never be complacent in what you understand. If I had never gotten my master’s, there would be this whole level of critical thinking that I wouldn’t have right now. Learning more is one of the biggest reasons why I want to get my PhD even if I don’t know exactly what I want to do yet.

I want to be able to think at a higher level because I think it’s valuable. And I see my Professor at Scripps: he has all these publications under his belt, but he’s always tinkering with things and he’s always learning new software and he’s always reading new papers. As a scientist, you can’t be stagnant in your learning, and I think because of that you’re always pushing yourself to your best potential.
Q: Do you have advice for future Bridges students?

JT: For anyone who is interested in doing a PhD, this is the world’s best preparatory program. After you start a PhD, you hit the ground running. If I were to give advice, I’d say to not be too hard on yourself. There’s going to be expectations put on you that you might not be ready for and you might not do the best job. But you should try your best and know it’s going to help you grow.

Usually people who go into PhD programs are people that have always done well in school. But it’s important to know that learning in grad school is very different than how we are taught to learn elsewhere. Every other time it’s just like show up, listen, take the test you’re done. A PhD relies on a little bit of luck, getting the right project, and doing everything meticulously.

Q: What are your hobbies?

JT: My favorite hobby is improv comedy. What I really like about improv is that it is so different from science and it helps me to relax after work.

Improv is performing comedic scenes on stage with a bunch of people without a script. Skills that it requires are not being stuck in your own head and really paying attention to what’s going on around you. You also need to take big risks and not worry so much about what the end result is going to be, which is very different from research. It’s a nice break to be able to make big giant mistakes and know that after that day it doesn’t matter.

As a researcher, it’s hard to make friends, and even if you have friends, it’s hard to find the time to hang out with them. I love improv because it’s a built in activity. All of my friends outside of work are in improv. We show up and we play make believe together on stage – it’s just a really nice atmosphere. In improv we teach a philosophy that everything you have is enough. Everything you come in with is enough. It’s really nice, because being an adult is hard and life is hard. So it’s a nice thing to hear.

Q: Do you see yourself combining your passions for science and improve in the future?

JT: I do. I don’t know what I want to do yet as a career, but improv is such a big part of my identity that it will always play a role in my life. Improv is so important in communication and interpersonal connections. I believe everyone in science could benefit from it. Ideally, I will find a career that allows me to use both of these passions to help people.

Young Minds Shine Bright at the CIRM SPARK Conference

Yesterday was one of the most exciting and inspiring days I’ve had at CIRM since I joined the agency one year ago. We hosted the CIRM SPARK conference which brought together fifty-five high school students from across California to present their stem cell research from their summer internships.

The day was a celebration of their accomplishments. But it was also a chance for the students to hear from scientists, patient advocates, and clinicians about the big picture of stem cell research: to develop stem cell treatments and cures for patients with unmet medical needs.

Since taking on the role of the CIRM SPARK director, I’ve been blown away by the passion, dedication, and intelligence that our SPARK interns have shown during their short time in the lab. They’ve mastered techniques and concepts that I only became familiar with during my PhD and postdoctoral research. And even more impressive, they eloquently communicated their research through poster presentations and talks at the level of professional scientists.

During their internships, SPARK students were tasked with documenting their research experiences through blogs and social media. They embraced this challenge with gusto, and we held an awards ceremony to recognize the students who went above and beyond with these challenges.

I’d like to share the winning blogs with our readers. I hope you find them as inspiring and motivating as I do. These students are our future, and I look forward to the day when one of them develops a stem cell treatment that changes the lives of patients.

Am I crying or is my face uncontrollably sweating right now? I think I am doing both as I write about my unforgettable experiences over the course of the past 6 weeks and finalize my poster.

As I think back, I am very grateful for the takeaways of the research field, acquiring them through scientific journals, lab experiments with my mentor, and both formal and informal discourses. It seems impossible to describe all the episodes and occurrences during the program in this one blog post, but all I can say is that they were all unique and phenomenal in their own respective ways.

Gaining new perspectives and insights and being acquainted with many of the techniques, such as stereology, immunocytochemistry and immunohistochemistry my peers have utilized throughout their careers, proved to me the great impact this program can make on many individuals of the younger generation.

CIRM SPARK not only taught me the goings on behind the bench-to-bedside translational research process, but also morals, work ethics, and effective collaboration with my peers and mentors. My mentor, Gen, reiterated the importance of general ethics. In the process of making my own poster for the program, her words resonate even greater in me. Research, education, and other career paths are driven by proper ethics and will never continue to progress if not made the basic standard.

I am thankful for such amazing institutions: California Institute of Regenerative Medicine (CIRM) and Cedars-Sinai Medical Center for enabling me to venture out into the research career field and network. Working alongside with my fellow seven very brilliant friends, motivated me and made this journey very enjoyable. I am especially thankful my mentor, Gen, for taking the time to provide me with the best possible resources, even with her busy ongoing projects. She encouraged me to be the best that I am.

I believe, actually, I should say, I KNOW Cedars-Sinai’s CIRM SPARK program does a SUPERB and astounding job of cultivating life-long learners and setting exceptional models for the younger generation. I am hoping that many others will partake in this remarkable educational program.

I am overall very blessed to be part of a successful summer program. The end of this program does not mark the end of my passions, but sparks them to even greater heights.

When I found out about this opportunity, all I knew was that I had a fiery passion for learning, for that simple rush that comes when the lightbulb sputters on after an unending moment of confusion. I did not know if this passion would translate into the work setting; I sometimes wondered if passion alone would be enough to allow me to understand the advanced concepts at play here. I started at the lab nervous, tentative – was this the place for someone so unsure exactly what she wanted to be ‘when she grew up,’ a date now all too close on the horizon? Was I going to fit in at this lab, with these people who were so smart, so busy, people fighting for their careers and who had no reason to let a 16-year-old anywhere near experiments worth thousands of dollars in cost and time spent?

I could talk for hours about the experiments that I worked to master; about the rush of success upon realizing that the tasks now completed with confidence were ones that I had once thought only to belong to the lofty position of Scientist. I could fill pages and pages with the knowledge I gained, a deep and personal connection to stem cells and cell biology that I will always remember, even if the roads of Fate pull me elsewhere on my journey to a career.

The interns called the experience #CIRMSparkLab in our social media posts, and I find this hashtag so fitting to describe these last few months. While there was, of course, the lab, where we donned our coats and sleeves and gloves and went to work with pipets and flasks…There was also the Lab. #CIRMSparkLab is so much more than an internship; #CIRMSparkLab is an invitation into the worldwide community of learned people, a community that I found to be caring and vibrant, creative and funny – one which for the first time I can fully imagine myself joining “when I grow up.”

#CIRMSparkLab is having mentors who taught me cell culture with unerring patience and kindness. It is our team’s lighthearted banter across the biosafety cabinet; it is the stories shared of career paths, of goals for the present and the future. It is having mentors in the best sense of the word, trusting me, striving to teach and not just explain, giving up hours and hours of time to draw up diagrams that ensured that the concepts made so much sense to me.

#CIRMSparkLab is the sweetest ‘good-morning’ from scientists not even on your team, but who care enough about you to say hi, to ask about your projects, to share a smile. It is the spontaneity and freedom with which knowledge is dispensed: learning random tidbits about the living patterns of beta fish from our lab manager, getting an impromptu lecture about Time and the Planck Constant from our beloved professor as he passes us at lunch. It is getting into a passionate, fully evidence-backed argument about the merits of pouring milk before cereal that pitted our Stem Cell team against our Exosome team: #CIRMSparkLab is finding a community of people with whom my “nerdy” passion for learning does not leave me an oddball, but instead causes me to connect instantly and deeply with people at all ages and walks of life. And it is a community that, following the lead of our magnificent lab director, welcomed ten interns into their lab with open arms at the beginning of this summer, fully cognizant of the fact that we will break beakers, overfill pipet guns, drop gels, bubble up protein concentration assays, and all the while never stop asking, “Why? Why? Why? Is this right? Like this? WHY?”

I cannot make some sweeping statement that I now know at age 16 exactly what I want to do when I grow up. Conversely, to say I learned so much – or I am so grateful – or you have changed my life is simply not enough; words cannot do justice to those sentiments which I hope that all of you know already. But I can say this: I will never forget how I felt when I was at the lab, in the community of scientists. I will take everything I learned here with me as I explore the world of knowledge yet to be obtained, and I will hold in my heart everyone who has helped me this summer. I am truly a better person for having known all of you.

Thank you, #CIRMSparkLab.

As children, we all grew up with the companionship of our favorite television shows. We enjoyed sitcoms and other animations throughout our childhood and even as adults, there’s no shame. The goofy and spontaneous skits we enjoyed a laugh over, yet we did not pay much attention to the lessons they attempted to teach us. As a child, these shows play crucial roles in our educational endeavors. We are immediately hooked and tune in for every episode. They spark curiosity, as they allow our imaginations to run wild. For me, that is exactly where my curiosity stemmed and grew for science over the years. A delusional young girl, who had no idea what the reality of science was like.

You expect to enter a lab and run a full day of experimentations. Accidentally mix the wrong chemicals and discover the cure for cancer. Okay, maybe not mix the incorrect chemicals together, I learned that in my safety training class. The reality is that working in a lab was far from what I expected — eye opening. Working alongside my mentor Sarah Frail was one of the best ways I have spent a summer. It was not my ideal summer of sleeping in until noon, but it was worthwhile.

My experience is something that is a part of me now. I talk about it every chance I get, “Mom, can you believe I passaged cells today!” It changed the way I viewed the principles of science. Science is one of the most valuable concepts on this planet, it’s responsible for everything and that’s what I have taken and construed from my mentor. She shared her passion for science with me and that completed my experience. Before when I looked at cells, I did not know exactly what I was supposed to observe. What am I looking at? What is that pink stuff you are adding to the plate?

However, now I feel accomplished. It was a bit of a roller coaster ride, with complications along the way, but I can say that I’m leaving this experience with a new passion. I am not just saying this to please the audience, but to express my gratitude. I would have never even looked into Huntington’s Disease. When I first arrived I was discombobulated. Huntington’s Disease? Now I can proudly say I have a grasp on the complexity of the disease and not embarrass my mentor my calling human cells bacteria – quite embarrassing in fact.  I’m a professional pipette handler, I work well in the hood, I can operate a microscope – not so impressive, I have made possibly hundreds of gels, I have run PCRs, and my cells love me, what else can I ask for.

If you are questioning what career path you are to take and even if it is the slightest chance it may be a course in science, I suggest volunteering in a lab. You will leave with your questioned answered. Is science for me? This is what I am leaving my experience with. Science is for me.

Advancing Stem Cell Research at the CIRM Bridges Conference

Where will stem cell research be in 10 years?

What would you say to patients who wanted stem cell therapies now?

What are the most promising applications for stem cell research?

Why is it important for the government to fund regenerative medicine?

These challenging and thought-provoking questions were posed to a vibrant group of undergraduate and masters-level students at this year’s CIRM Bridges to Stem Cell Research and Therapy conference.

Educating the next generation of stem cell scientists

The Bridges program is one of CIRM’s educational programs that offers students the opportunity to take coursework at California state schools and community colleges and conduct stem cell research at top universities and industry labs. Its goal is to train the next generation of stem cell scientists by giving them access to the training and skills necessary to succeed in this career path.

The Bridges conference is the highlight of the program and the culmination of the students’ achievements. It’s a chance for students to showcase the research projects they’ve been working on for the past year, and also for them to network with other students and scientists.

Bridges students participated in a networking pitch event about stem cell research.

CIRM kicked off the conference with a quick and dirty “Stem Cell Pitch” networking event. Students were divided into groups, given one of the four questions above and tasked with developing a thirty second pitch that answered their question. They were only given ten minutes to introduce themselves, discuss the question, and pick a spokesperson, yet when each team’s speaker took the stage, it seemed like they were practiced veterans. Every team had a unique, thoughtful answer that was inspiring to both the students and to the other scientists in the crowd.

Getting to the clinic and into patients

The bulk of the Bridges conference featured student poster presentations and scientific talks by leading academic and industry scientists. The theme of the talks was getting stem cell research into the clinic and into patients with unmet medical needs.

Here are a few highlights and photos from the talks:

On the clinical track for Huntington’s disease

Leslie Thompson, Professor at UC Irvine, spoke about her latest research in Huntington’s disease (HD). She described her work as a “race against time.” HD is a progressive neurodegenerative disorder that’s associated with multiple social and physical problems and currently has no cure. Leslie described how her lab is heading towards the clinic with human embryonic stem cell-derived neural (brain) stem cells that they are transplanting into mouse models of HD. So far, they’ve observed positive effects in HD mice that received human neural stem cell transplants including an improvement in the behavioral and motor defects and a reduction in the accumulation of toxic mutant Huntington protein in their nerve cells.

Leslie noted that because the transplanted stem cells are GMP-grade (meaning their quality is suitable for use in humans), they have a clear path forward to testing their potential disease modifying activity in human clinical trials. But before her team gets to humans, they must take the proper regulatory steps with the US Food and Drug Administration and conduct further experiments to test the safety and proper dosage of their stem cells in other mouse models as well as test other potential GMP-grade stem cell lines.

Gene therapy for SCID babies

Morton Cowan, a pediatric immunologist from UC San Francisco, followed Leslie with a talk about his efforts to get gene therapy for SCID (severe combined immunodeficiency disease) off the bench into the clinic. SCID is also known as bubble-baby disease and put simply, is caused by a lack of a functioning immune system. SCID babies don’t have normal T and B immune cell function and as a result, they generally die of infection or other conditions within their first year of life.

Morton described how the gold standard treatment for SCID, which is hematopoietic or blood stem cell transplantation, is only safe and effective when the patient has an HLA matched sibling donor. Unfortunately, many patients don’t have this option and face life-threatening challenges of transplant rejection (graft-versus host disease). To combat this issue, Morton and his team are using gene therapy to genetically correct the blood stem cells of SCID patients and transplant those cells back into these patients so that they can generate healthy immune cells.

They are currently developing a gene therapy for a particularly hard-to-treat form of SCID that involves deficiency in a protein called Artemis, which is essential for the development of the immune system and for repairing DNA damage in cells. Currently his group is conducting the necessary preclinical work to start a gene therapy clinical trial for children with Artemis-SCID.

Treating spinal cord injury in the clinic

Casey Case, Senior VP of Research and Nonclinical Development at Asterias Biotherapeutics, gave an update on the CIRM-funded clinical trial for cervical (neck) spinal cord injury (SCI). They are currently testing the safety of transplanting different doses of their oligodendrocyte progenitor cells (AST-OPC1) in a group of SCI patients. The endpoint for this trial is an improvement in movement greater than two motor levels, which would offer a significant improvement in a patient’s ability to do some things on their own and reduce the cost of their healthcare. You can read more about these results and the ongoing study in our recent blogs (here, here).

Opinion: Scientists should be patient advocates

David Higgins gave the most moving speech of the day. He is a Parkinson’s patient and the Patient Advocate on the CIRM board and he spoke about what patient advocates are and how to become one. David explained how, these days, drug development and patient advocacy is more patient oriented and patients are involved at the center of every decision whether it be questions related to how a drug is developed, what side effects should be tolerated, or what risks are worth taking. He also encouraged the Bridges students to become patient advocates and understand what their needs are by asking them.

David Higgins, Parkinson's advocate and CIRM Board member

David Higgins

“As a scientist or clinician, you need to be an ambassador. You have a job of translating science, which is a foreign language to most people, and you can all effectively communicate to a lay audience without being condescending. It’s important to understand what patients’ needs are, and you’ll only know that if you ask them. Patients have amazing insights into what needs to be done to develop new treatments.”

Bridging the gap between research and patients

The Bridges conference is still ongoing with more poster presentations, a career panel, and scientific talks on discovery and translational stem cell research and commercializing stem cell therapies to all patients in need. It truly is a once in a lifetime opportunity for the Bridges students, many of whom are considering careers in science and regenerative medicine and are taking advantage of the opportunity to talk and network with prominent scientists.

California high schoolers SPARK interest in stem cell research through social media

I have a job for you today and it’s a fun one. Open your Instagram app on your phone. If you’re not an Instagrammer, don’t worry, you can access the website on your computer.

Do you have it open? OK now type in the hashtag #CIRMSparkLab and click on it.

What you’ll find is around 200 posts of the most inspiring and motivating pictures of stem cell research that I’ve seen. These pictures are from high school students currently participating in the CIRM summer SPARK program, one of our educational programs, which has the goal to train the next generation of stem cell scientists.

The SPARK program offers California high school students an invaluable opportunity to gain hands-on training in regenerative medicine at some of the finest stem cell research institutes in the state. And while they gain valuable research skills, we are challenging them to share their experiences with the general public through blogging and social media.

Communicating science to the public is an important mission of CIRM, and the SPARK students are excelling at this task by posting descriptive photos on Instagram that document their internships. Some of them are fun lab photos, while others are impressive images of data with detailed explanations about their research projects.

Below are a few of my favorite posts so far this summer. I’ve been so inspired by the creativity of these posts that we are now featuring some of them on the @CIRM_Stemcells account. (Yes this is a shameless plug for you to follow us on Instagram!).

I encourage you all to follow our talented SPARK students this summer as they continue to document their exciting journeys on Instagram. These students are our future and supporting their training and education in stem cell research is an honor for CIRM and a vital step towards achieving our mission of accelerating stem cell treatments to patients with unmet medical needs.

Stay tuned for more blog coverage about SPARK and our other educational program, the Bridges to Stem Cell Research program for undergraduate and master-level students. The annual Bridges conference that brings all the students together to present their research will be held next week, and the SPARK conference is on August 8th both in Berkeley.

Knowledge is on the menu at Dinner with a Scientist:

Helen Budworth, Ph.D., is one of the Science Officers at CIRM. She wrote this blog about her experiences talking to some budding local scientists who just happen to be ten years old.kids dinner

Recently I had the pleasure of attending the Oakland Unified School District (OUSD) “Dinner with a Scientist” event held at the Oakland Zoo. OUSD has been hosting this annual event since 2009 to bring together local scientists, teachers, and students to celebrate science in an evening of activities and science conversation.

I was dining with 4th and 5th grade elementary students and their teachers from Think College Now and from Brookfield Elementary in Oakland. They included many budding scientists, with interests ranging from biology and chemistry, to geology and astronomy. The students were eager to learn about how I became a scientist, what interests me about my job and how they can prepare themselves for a future scientific career. I explained that my interest in science began in childhood because I loved puzzles and really enjoyed trying to work things out, and that my interest in science naturally flowed from that. Both students and teachers alike were interested to learn more about CIRM and what our scientists are working on.

The evening began with the students being asked a simple question: “What is science?” One of the kids said it was finding out new things; another said it meant conducting experiments to answer questions. One said it was a way of making money. He’s in for a rude surprise when he grows up!

In order to demonstrate the potential of stem cells, I led an activity that allowed the groups to use Play Doh to model the early stages of human development from a zygote, the earliest stage of a fertilized egg, through the first few weeks of embryonic development. What I learned from this event is that when you ask a 4th/5th grader if they know how babies are made, you will get many giggles and some interesting descriptions of ways that sperm and egg can meet – but few details of what happens after that.

This hands-on activity showed the students the processes of cell division, differentiation and development of a multi-cellular organism from a single-celled zygote. Scientific studies of stem cells, such as those found at early stages of development, have allowed us to reach the point where we are now harnessing the power of these cells to create treatments for diseases. They were very intrigued by the idea that you begin life as a single cell, that grows and multiplies and changes until all those cells become the different parts of you and creates a whole human being.

The exercise, indeed the whole evening, gave the students an opportunity to see how scientific careers are translated to real world applications and will hopefully inspire some future scientists and doctors.

I asked one of the students what kind of scientist she wanted to be, and she replied that she wanted to be a chemist. When I asked why she said because she likes mixing things. That seems as good a reason to think about a career in science as any.
