Science is full of acronyms. There are days where it feels like you need a decoder ring just to understand a simple sentence. A recent study found that between 1950 and 2019 researchers used more than 1.1 million unique acronyms in scientific papers. There’s even an acronym for three letter acronyms. It’s TLAs. Which of course has one more letter than the thing it stands for.
I only mention this because I just learned a new acronym, but this one could help change the way we are able to study causes of infertility. The acronym is IVG or in vitro gametogenesis and it could enable scientists to create both sperm and egg, from stem cells, and grow them in the lab. And now scientists in Japan have done just that and allowed these fertilized eggs to then develop into mice.
The study, published in the journal Science, was led by Dr. Katsuhiko Hayashi of Kyushu University in Japan. Dr. Hayashi is something of a pioneer in the field of IVG. In the past his team were the first to produce both mouse sperm, and mouse eggs from stem cells. But they ran into a big obstacle when they tried to get the eggs to develop to a point where they were ready to be fertilized.
Over the last five years they have worked to find a way around this obstacle and, using mouse embryonic stem cells, they developed a process to help these stem cell-generated eggs mature to the point where they were viable.
In an article in STAT News Richard Anderson, Chair of Clinical Reproductive Science at the University of Edinburgh, said this was a huge achievement: “It’s a very serious piece of work. This group has done a lot of impressive things leading up to this, but this latest paper really completes the in vitro gametogenesis story by doing it in a completely stem-cell-derived way.”
The technique could prove invaluable in helping study infertility in people and, theoretically, could one day lead to women struggling with infertility to be able to use their own stem cells to create eggs or men their own sperm. However, the researchers say that even if that does become possible it’s likely a decade or more away.
While the study is encouraging on a scientific level, it’s raising some concerns on an ethical level. Should there be limits on how many of these manufactured embryos that a couple can create? Can someone create dozens or hundreds of these embryos and then sift through them, using genetic screening tools, to find the ones that have the most desirable traits?
One thing is clear, while the science is evolving, bioethicists, scholars and the public need to be discussing the implications for this work, and what kinds of restraints, if any, need to be applied before it’s RFPT (ready for prime time – OK, I made that one up.)
Transplanting cells or an entire organ from one person to another can be lifesaving but it comes with a cost. To avoid the recipient’s body rejecting the cells or organ the patient has to be given powerful immunosuppressive medications. Those medications weaken the immune system and increase the risk of infections. But now a team at the University of California San Francisco (UCSF) have used a new kind of stem cell to find a way around that problem.
The cells are called HIP cells and they are a specially engineered form of induced pluripotent stem cell (iPSC). Those are cells that can be turned into any kind of cell in the body. These have been gene edited to make them a kind of “universal stem cell” meaning they are not recognized by the immune system and so won’t be rejected by the body.
The UCSF team tested these cells by transplanting them into three different kinds of mice that had a major disease; peripheral artery disease; chronic obstructive pulmonary disease; and heart failure.
The results, published in the journal Proceedings of the National Academy of Science, showed that the cells could help reduce the incidence of peripheral artery disease in the mice’s back legs, prevent the development of a specific form of lung disease, and reduce the risk of heart failure after a heart attack.
In a news release, Dr. Tobias Deuse, the first author of the study, says this has great potential for people. “We showed that immune-engineered HIP cells reliably evade immune rejection in mice with different tissue types, a situation similar to the transplantation between unrelated human individuals. This immune evasion was maintained in diseased tissue and tissue with poor blood supply without the use of any immunosuppressive drugs.”
Deuse says if this does work in people it may not only be of great medical value, it may also come with a decent price tag, which could be particularly important for diseases that affect millions worldwide.
“In order for a therapeutic to have a broad impact, it needs to be affordable. That’s why we focus so much on immune-engineering and the development of universal cells. Once the costs come down, the access for all patients in need increases.”
When the voters of California approved Proposition 14 last November (thanks folks) they gave us $5.5 billion to continue the work we started way back in 2014. It’s a great honor, and a great responsibility.
It’s also a great opportunity to look at what we do and how we do it and try to come up with even better ways of funding groundbreaking research and helping create a new generation of researchers.
In addition to improving on what we already do, Prop 14 introduced some new elements, some new goals for us to add to the mix, and we are in the process of fleshing out how we can best do that.
Because of all these changes we decided it would be a good idea to hold a “Town Hall” meeting and let everyone know what these changes are and how they may impact applications for funding.
The Town Hall, on Tuesday June 29, was a great success with almost 200 participants. But we know that not everyone who wanted to attend could, so here’s the video of the event, and below that are the questions that were posed by people during the meeting, and the answers to those questions.
Having seen the video we would be eternally grateful if you could respond to a short online survey, to help us get a better idea of your research and education needs and to be better able to serve you and identify potential areas of opportunity for CIRM. Here’s a link to that survey: https://www.surveymonkey.com/r/VQMYPDL
We know that there may be issues or questions that are not answered here, so feel free to send those to us at email@example.com and we will make sure you get an answer.
Are there any DISC funding opportunities specific to early-stage investigators?
DISC funding opportunities are open to all investigators. There aren’t any that are specific to junior investigators.
Are DISC funding opportunities available for early-mid career researchers based out of USA such as Australia?
Sorry, you have to be in California for us to fund your work.
Does tumor immunology/ cancer immunotherapy fall within the scope of the CIRM discovery grants?
CIRM funding supports non-profit academic grantees as well as companies of all sizes.
I am studying stem cells using mouse. Is my research eligible for the CIRM grants?
Yes it is.
Your programs more specifically into stem cell research would be willing to take patients that are not from California?
Yes, we have treated patients who are not in California. Some have come to California for treatment and others have been treated in other states in the US by companies that are based here in California.
Can you elaborate how the preview of the proposals works? Who reviews them and what are the criteria for full review?
The same GWG panel both previews and conducts the full review. The panel first looks through all the applications to identify what each reviewer believes represents the most likely to be impactful and meet the goals of the CIRM Discovery program. Those that are selected by any reviewer moves forward to the next full review step.
If you meet your milestones-How likely is it that a DISC recipient gets a TRAN award?
The milestones are geared toward preparation of the TRAN stage. However, this is a different application and review that is not guaranteed to result in funding.
Regarding Manufacturing Public Private partnerships – What specific activities is CIRM thinking about enabling these partnerships? For example, are out of state for profit commercial entities able to conduct manufacturing at CA based manufacturing centers even though the clinical program may be primarily based out of CA? If so, what percent of the total program budget must be expended in CA? How will CIRM enable GMP manufacturing centers interact with commercial entities?
We are in the early stages of developing this concept with continued input from various stakeholders. The preliminary vision is to build a network of academic GMP manufacturing centers and industry partners to support the manufacturing needs of CIRM-funded projects in California.
We are in the process of widely distributing a summary of the manufacturing workshop. Here’s a link to it:
If a center is interested in being a sharing lab or competency hub with CIRM, how would they go about it?
CIRM will be soliciting applications for Shared Labs/Competency hubs in potential future RFAs. The survey asks several questions asking for feedback on these concepts so it would really help us if you could complete the survey.
Would preclinical development of stem cell secretome-derived protein therapies for rare neuromuscular diseases and ultimately, age-related muscle wasting be eligible for CIRM TRAN1 funding? The goal is to complete IND-enabling studies for a protein-based therapy that enhances tissue regeneration to treat a rare degenerative disease. the screening to identify the stem-cell secreted proteins to develop as therapeutics is done by in vitro screening with aged/diseased primary human progenitor cells to identify candidates that enhance their differentiation . In vivo the protein therapeutic signals to several cell types , including precursor cells to improve tissue homeostasis.
I would suggest reaching out to our Translation team to discuss the details as it will depend on several factors. You can email the team at firstname.lastname@example.org
There are many unknown elements for what triggers the cells in an embryo to start dividing and multiplying and becoming every single cell in the body. Now researchers at the Gladstone Institutes in San Francisco have uncovered one of those elements, how embryos determine which cells become the head and which the tail.
In this CIRM-funded study the Gladstone team, led by Dr. Todd McDevitt, discovered almost by chance how the cells align in a heads-to-tail arrangement.
They had created an organoid made from brain cells when they noticed that some of the cells were beginning to gather in an elongated fashion, in the same way that spinal cords do in a developing fetus.
In a news article, Nick Elder, a graduate student at Gladstone and the co-author of the study, published in the journal Development, says this was not what they had anticipated would happen: “Organoids don’t typically have head-tail directionality, and we didn’t originally set out to create an elongating organoid, so the fact that we saw this at all was very surprising.”
Further study enabled the team to identify which molecules were involved in signaling specific genes to switch on and off. These were similar to the process previously identified in developing mouse embryos.
“This is such a critical point in the early development of any organism, so having a new model to observe it and study it in the lab is very exciting,” says McDevitt.
This is not just of academic interest either, it could have real world implications in helping understand what causes miscarriages or birth defects.
“We can use this organoid to get at unresolved human developmental questions in a way that doesn’t involve human embryos,” says Dr. Ashley Libby, another member of the team. “For instance, you could add chemicals or toxins that a pregnant woman might be exposed to, and see how they affect the development of the spinal cord.”
When Proposition 14 was approved by voters in November we were given a chance to carry on the work we have been doing for more than 16 years. What we hadn’t anticipated was that we would also get a chance to do that with some of the team that helped us make CIRM what it is, but who had since moved on to other jobs.
We are delighted to say that as we build up our team again we are welcoming back a couple of dear friends, and welcoming in some new ones too. They’re a talented bunch and, if they don’t mind me saying so, a darned good looking group too.
Rosa Canet-Aviles, PhD., has been named as the new Vice President Scientific Programs. Rosa is a familiar face at the agency, serving as a Science Officer with CIRM from 2008 to 2014. During that time she helped oversee the development of our Translational program, managed a broad portfolio of projects and organized workshops on Parkinson’s and autism.
After leaving CIRM she joined the Foundation for the National Institutes of Health (FINH) where she served as the Director of Neuroscience Research Partnerships. In that role she led the successful development and management of 5 new large partnerships including the Biomarkers Consortium Neuroscience Steering Committee, the Accelerating Medicines Partnership (AMP) for Alzheimer’s disease 1.0 and 2.0, AMP Parkinson’s disease and AMP Schizophrenia.
Rosa has more than 15 years of experience working in industry, academia and government and her experience in developing and managing neuroscience programs will be invaluable as CIRM looks to invest some $1.5 billion in neuroscience under Proposition 14.
“I am very excited to be back,” says Rosa. ”It is a dream come true being able to translate all the skills, learning and networks gathered over the past 7 years towards the development and implementation of CIRM’s new phase and accelerate stem cell therapies for patients in need.”
“We are thrilled to announce the timely return of Rosa to CIRM as we build our new strategic plan under Prop 14,” says Dr. Maria T. Millan, CIRM’s President & CEO. “Rosa has demonstrated time and again the unique ability to bring together often seemingly disparate stakeholders to successfully drive toward a common goal of advancing the science on behalf of patients with diseases of the brain and neuropsychiatric disorders. At CIRM, she assembled key international leaders who went on to form an international Parkinson’s Disease consortium. At the Foundation for NIH (FNIH), she directed the development of five prominent public-private partnerships. A neuroscientist by training, she is held in high regard and has been called a “quick study” in her ability to lead in new areas such as in genomics and data science, key components of her role at FNIH and at Eisai’s Center for Genetics Guided Dementia Discovery.“
In addition, CIRM is pleased to announce the following new team members:
Uta Grieshammer, PhD. is also returning to CIRM as the Senior Science Officer for our Discovery program. Uta was at CIRM from 2007 to 2015 and led the programs that created both our Genomics Initiative and our iPSC bank. She also organized several scientific conferences and workshops involving hundreds of CIRM-funded researchers.
After leaving CIRM she became the Scientific Director of the California Initiative to Advance Precision Medicine at the University of California San Francisco where she created and managed the application and peer review process. Most recently she was the Program Officer at the University of California Office of the President’s (UCOP) Tobacco Related Disease Research Program where she focused on the neuroscience of nicotine addiction. She also helped develop a scholarship program to attract students from diverse backgrounds to pursue a career in science.
Michael Bunch joins CIRM as a Business Service Officer. Michael is a decorated veteran who has been working as the Chief Business Officer at the Veterans Home in Yountville, California. In that role he implemented new contract and reviewing processes and oversaw the income and insurance tracking for some 1,000 residents. With his extensive background in acquisition management, contingency contracting, and his deep knowledge of state regulations and guidelines Michael was able to increase funding, streamline processes and assist Veterans and their families to obtain the benefits and services that they qualified for.
Michael spent 25 years in the US Army including serving as part of the NATO peacekeeping force in Kosovo. During that deployment he was awarded the Joint Service Commendation Medal (JSCM) for managing the fuel needs of 4 Multinational Task Forces and 33 Nations, an essential element in helping the mission succeed.
A Senior Drill Sergeant, Infantry Instructor and Financial and Resource Manager Michael has been awarded the Army Commendation Medal with 4 Oak Leaves, Army Achievement Medal with 4 Oak Leaves, Global War on Terrorism Service Medal, KOSOVO Campaign Medal, Military Outstanding Volunteer Service Medal, NATO Medal, Expert Infantryman Badge, Honorary Kentucky Colonel and Honorary Kentucky Admiral.
Nellie Almazan joins CIRM as a Grants Management Specialist. Nellie comes to us from the California Department of Transportation (Caltrans) where she has worked for 16 years, most recently as the Associate Transportation Planner with the Low Carbon Transit Operations program. Nellie managed more than 150 projects, reviewing grants to help reduce greenhouse gas emissions in the state and overseeing programs that had an emphasis on serving Disadvantaged Communities.
She is currently enrolled at Sacramento City College where her focus is on Sociology and Deaf Culture.
Alexandra Caraballo joins CIRM as a Grants Management Specialist. Alex has more than 15 years of grant administration experience with a focus on incorporating equity, diversity, and inclusion into grantmaking practices and decision-making. She comes to CIRM from the Kaiser Foundation Health Plan where she was the National Manager of Philanthropy. There she was responsible for the administration of approximately 200 grants in the national community health portfolio. Before Kaiser she was the Program Assistant and Associate Program Officer at the East Bay Community Foundation, where she partnered with donors and community-based organizations to advance racial equity and transform political, social and economic outcomes for East Bay Communities.
Alex currently serves on the Board of Directors for the Lindsay Wildlife Experience and was a former Advisory Board member for Oakland Head Start.
Over the last year there has been increasing awareness of the inequalities in the American healthcare system. At every level there is evidence of bias, discrimination and unequal access to the best care. Sometimes unequal access to any care. That is, hopefully, changing but only if the new awareness is matched with action.
At the recent World Stem Cell Summit CIRM helped pull together a panel of physicians and patient advocates who have been leading the charge for change for years. The panel was called ‘Addressing Disparities, Promoting Equity and Inclusion in Clinical Research.’
The panelists include:
The conversation they had was informative, illuminating and fascinating. But it didn’t sugar coat where we are, and the hard work ahead of us to get to where we need to be.
Enjoy the event, with apologies for the inept cameo appearance by me at the beginning of the video. Technology clearly isn’t my forte.
It’s hard enough trying to follow the movements of individuals in a crowd of people but imagine how much harder it is to follow the movements of stem cells, crowded into a tiny petri dish. Well, researchers at the Gladstone Institutes in San Francisco have done just that.
In a CIRM-funded study ($5.85M) Dr. Todd McDevitt and his team created a super smart artificial intelligence way of tracking the movements of hundreds of stem cells growing together in a colony, and even identify “leaders” in the pack.
In our bodies groups of stem cells are able to move in specific ways to form different organs and tissues when exposed to the right environment. Unfortunately, we are still trying to learn what “the right environment” is for different organs.
In a news release, McDevitt, the senior author of the paper published in the journal Stem Cell Reports, says this method of observing cells may help us better understand that.
“If I wanted to make a new human heart right now, I know what types of cells are needed, and I know how to grow them independently in dishes. But we really don’t know how to get those cells to come together to form something as complex as a heart. To accomplish that, we need more insights into how cells work cooperatively to arrange themselves.”
Normally scientists watch cells by tagging them with a fluorescent marker so they can see them under a microscope. But this is slow, painstaking work and not particularly accurate. This new method used a series of what are called “neural networks”, which are artificial intelligence (AI) programs that can detect patterns in the movements of the cells. When combined together the networks proved to be able to track the movement of 95 percent of the cells. Humans by comparison can only manage up to 90 percent. But the nets were not only sharper, they were also faster, much faster, some 500 times faster.
This enhanced ability to watch the cells showed that instead of being static most of the time, as had previously been thought, they were actually on the move a lot of the time. They would move around for 15 minutes and then take a breather for ten minutes (time for the stem cell equivalent of a cup of tea perhaps).
Some cells moved around a lot in one direction, while others just seemed to shuffle around in the same area. Some cells even seemed to act as “leaders” while other cells appeared to be “followers” and shuffle along behind them.
None of this would have been visible without the power of the AI networks and McDevitt says being able to tap into this could help researchers better understand how to use these complex movements.
“This technique gives us a much more comprehensive view of how cells behave, how they work cooperatively, and how they come together in physical space to form complex organs.
Follow the Leader is not just a kids’ game anymore. Now it’s a scientific undertaking.
Way, way back in 2015 – seems like a lifetime ago doesn’t it – the team at CIRM sat down and planned out our Big 6 goals for the next five years. The end result was a Strategic Plan that was bold, ambitious and set us on course to do great things or kill ourselves trying. Well, looking back we can take some pride in saying we did a really fine job, hitting almost every goal and exceeding them in some cases. So, as we plan our next five-year Strategic Plan we thought it worthwhile to look back at where we started and what we achieved. Goal #5 was Advance.
A dictionary definition of progression is “The act of moving forward or proceeding in a course.” That’s precisely what we set out to do when we set one of the goals in our 2015 Strategic Plan. We wanted to do all that we could to make sure the work we were funding could advance to the next stage. The goal we set was:
Advance: Increase projects advancing to the next stage of development by 50%.
The first question we faced was what did we mean by progression and how were we going to measure it? The answer basically boiled down to this: when a CIRM award completes one stage of research and gets CIRM funding to move on to the next stage or to develop a second generation of the same device or therapy.
In the pre-2016 days we’d had some success, on average getting around nine progression events every year. But if we were going to increase that by 50 percent we knew we had to step up our game and offer some incentives so that the team behind a successful project had a reason, other than just scientific curiosity, to try and move their research to the next level.
So, we created a series of linkages between the different stages of research, so the product of each successful investment was the prerequisite for the next stage of development for the research or technology.
We changed the way we funded projects, going from offering awards on an irregular basis to having them happen according to a pre-defined schedule with each program type offered multiple times a year. This meant potential applicants knew when the next opportunity to apply would come, enabling them to prepare and file at the time that was best for them and not just because we said so. We also timed these schedules so that programs could progress from one stage to the next without interruption.
But that’s not all. We recognized that some people may be great scientists at one level but didn’t have the experience or expertise to carry their project forward. So, we created both an Accelerating Center and Translating Center to help them do that. The Translating Center helped projects do the work necessary to get ready to apply to the US Food and Drug Administration (FDA) for permission to start a clinical trial. The Accelerating Center helped the team prepare that application for the trial and then plan how that trial would be carried out.
Creating these two centers had an additional benefit; it meant the work that did progress did so faster and was of a higher quality than it might otherwise have been.
Putting all those new building blocks in place meant a lot of work for the CIRM team, on top of their normal duties. But, as always, the team rose to the challenge. By the end of December 2020, a total of 74 projects had advanced or progressed to the next level, an increase of 100 percent on our pre-2016 days.
When we were laying out the goals we said that “The full implementation of these programs will create the chassis of a machine that provides a continuous, predictable, and timely pathway for the discovery and development of promising stem cell treatments.” Thanks to the voter approved Proposition 14 we now have the fund to help those treatments realize that promise.
Way, way back in 2015 – seems like a lifetime ago doesn’t it – the team at CIRM sat down and planned out our Big 6 goals for the next five years. The end result was a Strategic Plan that was bold, ambitious and set us on course to do great things or kill ourselves trying. Well, looking back we can take some pride in saying we did a really fine job, hitting almost every goal and exceeding them in some cases. So, as we plan our next five-year Strategic Plan we thought it worthwhile to look back at where we started and what we achieved. Goal #3 was Discover.
When journalists write about science a lot of the attention is often focused on clinical trials. It’s not too surprising, that’s the stage where you see if treatments really work in people and not just in the lab. But long before you get to the clinical trial stage there’s a huge amount of work that has to be done. The starting point for that work is in the Discovery stage, if it works there it moves to the Translational stage, and only after that, assuming it’s still looking promising, does it start thinking about moving into the clinic.
The Discovery, or basic, stage of research is where ideas are tested to see if they have any promise and have the potential to lead to the development of a therapy or device that could ultimately help patients. In many ways the goal of Discovery research is to gain a better understanding of how, in our case, stem cells work, and how to harness that power to treat particular diseases or disorders.
Without a rigorous Discovery research program you can’t begin to create a pipeline of promising projects that you can advance towards patients. And of course having a strong Discovery program is not much use if you don’t have somewhere for those projects to advance to, namely Translational and ultimately clinical.
So, when we were laying out our Strategic Plan goals back in 2015 we wanted to create a pipeline for all three programs, moving the most promising ones forward. So we set an ambitious goal.
Introduce 50 new therapeutic or device candidates into development.
Now this doesn’t mean just fund 50 projects hoping to develop a new therapy or device. A lot of studies that are funded, particularly at the earliest stages, have a good idea that just doesn’t pan out. In fact one quite common definition of early research – in this case from Translational Medicine Communications – is “the earliest stage of research, conducted for the advancement of knowledge, often without any concern for its practical applications.
That’s not what we wanted. We aren’t in this to do research just for its own sake. We fund research because we want it to lead somewhere, we want it to have a practical application. We want to fund projects that actually ended up with something much more promising, a candidate that might actually work and was ready to move into the next level of research to test it further.
And we almost, almost made it to the 50-candidate goal. We got to 46 and almost certainly would have made it to 50 if we hadn’t run out of money. Even so, that’s pretty impressive. There are now 46 projects ready to move on, or are already moving on, to the next level of research.
Of course, there’s no guarantee that these will ultimately end up as an FDA-approved therapy or device. But if you don’t set goals, you’ll never score. And now, thanks to the passage of Proposition 14, we have a chance to support those projects as they move forward.
Throughout history, matchmakers have played an important role in bringing together couples for arranged marriages. Fast forward to today and CIRM is now playing a similar role. We’re not looking to get anyone hitched, what we are trying to do is create partnerships between people we are funding and companies looking for the next hot thing.
So far, I’d say we are doing a pretty decent job. Over the years we have leveraged our funding to bring in some $13 billion in additional investments in stem cell research. But there’s still a lot of untapped potential out there. That’s why tomorrow, March 9th, we’re joining with BIOCOM to host a Partner Day.
The idea is to highlight some of the most promising programs we are funding and see if we can find partners for them, partners who want to help advance the research and ultimately – we hope – bring those therapies to patients.
The webinar and panel discussion will feature a presentation from the CIRM Business Development team about our portfolio. That’s a pretty extensive list because it covers all stages of research from Discovery or basic, through Translational and all the way to Clinical. We’ll show how our early investment in these programs has helped de-risk them and given them the chance to get the data needed to demonstrate their promise and potential.
So, who are we interested in having join us? Pretty nearly everyone involved in the field:
Venture capital firms
And the areas of interest are equally broad:
Stem or progenitor cell-based therapy
And for those who are really interested and don’t want to waste any time, there’s an opportunity to set up one-on-one meetings right away. After all, if you have found the perfect match, why wait!
But here’s the catch. Space is limited so you need to register ahead. Here’s where you go to find out all the details and sign up for the event.
