We spend around one third of our life sleeping—or at least we should. Not getting enough sleep can have serious consequences on many aspects of our health and has been linked to high blood pressure, heart disease and stroke.
A study by the American Sleep Apnea Association found that some 70 percent of Americans report getting too little sleep at least one night a month, and 11 percent report not enough sleep every night. Over time that can take a big toll on your mental and physical health. Now a new study says that impact can also put you at increased risk for eye disease.
The study published in the journal Stem Cell Reports, looked at how sleep deprivation affects corneal stem cells. These cells are essential in replacing diseased or damaged cells in the cornea, the transparent tissue layer that covers and protects the eye.
Researchers Wei Li, Zugou Liu and colleagues from Xiamen University, China and Harvard Medical School, USA, found that, in mice short-term sleep deprivation increased the rate at which stem cells in the cornea multiplied. Having too many new cells created vision problems.
They also found that long-term sleep deprivation had an even bigger impact on the health of the cornea. Sleep-deprived mice had fewer active stem cells and so were not as effective in replacing damaged or dying cells. That in turn led to a thinning of the cornea and a loss of transparency in the remaining cells.
The findings suggest that sleep deprivation negatively affects the stem cells in the cornea, possibly leading to vision impairment in the long run. It’s not clear if these findings also apply to people, but if they do, the implications could be enormous.
While there have been some encouraging advances in treating cancer in recent decades, there are still many cancers that either resist treatment or recur after treatment. Today the governing Board of the California Institute for Regenerative Medicine (CIRM) approved investing in a therapy targeting some of these hard-to-treat tumors.
BioEclipse Therapeutics Inc. was awarded nearly $8M to test a therapy using immune cells loaded with a cancer-killing virus that targets cancer tissue but spares healthy tissue.
BioEclipse combines two approaches—an immune cell called a cytokine-induced killer (CIK) cell and a virus engineered to kill cancer cells called an oncolytic virus (OV)—to create what they call “a multi-mechanistic, targeted treatment.”
They will use the patient’s own immune cells and, in the lab, combine them with the OV. The cell/virus combination will then be administered back to the patient. The job of the CIK cells is to carry the virus to the tumors. The virus is designed to specifically attack and kill tumors and stimulate the patient’s immune system to attack the tumor cells. The goal is to eradicate the primary tumor and prevent relapse and recurrence.
“With the intent to develop this treatment for chemotherapy-resistant or refractory solid tumors—including colorectal cancer, triple negative breast cancer, ovarian cancer, gastric cancer, hepatocellular carcinoma, and osteosarcoma—it addresses a significant unmet medical need in fatal conditions for which there are limited treatment options,” says Dr. Maria T. Millan, President and CEO of CIRM.
The CIRM Board also approved more than $18 million in funding four projects under the Translation Projects program. The goal of this program is to support promising regenerative medicine (stem cell-based or gene therapy) projects that accelerate completion of translational stage activities necessary for advancement to clinical study or broad end use.

When Anna Kuehl began losing her vision, she feared losing the ability to read and go on long walks in nature—two of her favorite pastimes. Anna had been diagnosed with age-related macular degeneration, the leading cause of vision loss in the US. She lost the central vision in her left eye, which meant she could no longer make out people’s faces clearly, drive a car, or read the time on her watch.
The treatment sprang out of research done by Dr. Mark Humayun and his team at USC. In collaboration with Regenerative Patch Technologies they developed a stem cell-derived implant using cells from a healthy donor. The implant was then placed under the retina in the back of the eye. The hope was those stem cells would then repair and replace damaged cells and restore some vision.
In the past, using donor cells meant that patients often had to be given long-term immunosuppression to stop their body’s immune system attacking and destroying the patch. But in this trial, the patients were given just two months of immunosuppression, shortly before and after the implant procedure.
In a news story on the USC website, Dr. Humayun said this was an important advantage. “There’s been some debate on whether stem cells derived from a different, unrelated person would survive in the retina without long-term immunosuppression. For instance, if you were to receive a kidney transplant, long-term immunosuppression would be required to prevent organ rejection. This study indicates the cells on the retinal implant can survive for up to two years without long-term immunosuppression.”
Cells show staying power
When one of the patients in the clinical trial died from unrelated causes two years after getting the implant, the research team were able to show that even with only limited immunosuppression, there was no evidence that the patient’s body was rejecting the donor cells.
“These findings show the implant can improve visual function in some patients who were legally-blind before treatment and that the cells on the implant survive and remain functional for at least two years despite not being matched with those of the patient,” Humayun said.
For Anna Kuehl, the results have been remarkable. She was able to read an additional 17 letters on a standard eye chart. Even more importantly, she is able to read again, and able to walk and enjoy nature again.
Dr. Humayun says the study—published in the journal Stem Cell Reports—may have implications for treating other vision-destroying diseases. “This study addresses the debate over the viability of using mismatched stem cells — this shows that a mismatched stem cell derived implant can be safe and viable over multiple years.”
About one third of stroke survivors experience vision loss. It can be a devastating side effect as most patients will not fully recover their vision and there are currently no reliable treatments available. But thanks to a collaborative effort by two teams of researchers from Purdue University and Jinan University in China, there may be a way to use gene therapy to recover lost vision after a stroke.
A stroke happens when part of the brain is starved of oxygen which can result in death of brain cells or neurons. Oftentimes this is caused by a blockage in an artery in the brain. Given the location of these vital arteries, most strokes lead to loss of motor function and in some cases, permanent vision loss.
The brain is an incredible machine and capable of remapping its neural pathways enough to restore some visual function, but this isn’t always the case. The neurons that are destroyed in the process of experiencing a stroke do not regenerate and lose their ability to communicate/transmit information between different areas of the brain, and between the brain and the rest of the nervous system.
Two research teams, one led by Alexander Chubykin at Purdue University’s and the other led by Gong Chen at Jinan University, have taken a different approach to neural regeneration by reprogramming local glial cells into neurons, therefore restoring connections between the old neurons and the newly reprogrammed neurons.
In a news release, Dr. Chubykin says the results in the lab look promising. “We can watch the mice get their vision back. We don’t have to implant new cells, so there’s no immunogenic rejection. This process is easier to do than stem cell therapy, and there’s less damage.”
The collaborative research, published in the journal Frontiers in Cell and Developmental Biology, is promising not only in aiding with vision restoration after a stroke but could also lead to similar treatment for reestablishing motor function. Visual function is easier than motor skills to measure accurately and the scientists are looking into the effectiveness of this procedure in live mice using advanced optical imaging tools. If the study continues to provide positive results, it might not be long before human trials are started.
As someone who is not always as diligent as he would like to be about sending birthday cards on time, I’m used to sending belated greetings to people. So, I have no shame in sending belated greetings to four CIRM grantees who were inducted into the National Academy of Medicine in 2020.
I say four, but it’s really three and a half. I’ll explain that later.
Being elected to the National Academy of Medicine is, in the NAM’s own modest opinion, “considered one of the highest honors in the fields of health and medicine and recognizes individuals who have demonstrated outstanding professional achievement and commitment to service.”
To be fair, NAM is right. The people elected are among the best and brightest in their field and membership is by election from the other members of NAM, so they are not going to allow any old schmuck into the Academy (which could explain why I am still waiting for my membership).
The CIRM grantees elected last year are:
Antoni Ribas, MD, PhD, professor of medicine, surgery, and molecular and medical pharmacology, U. C. Los Angeles.
Dr. Ribas is a pioneer in cancer immunology and has devoted his career to developing new treatments for malignant melanoma. When Dr. Ribas first started malignant melanoma was an almost always fatal skin cancer. Today it is one that can be cured.
In a news release Dr. Ribas said it was a privilege to be honored by the Academy: “It speaks to the impact immunotherapy has played in cancer research. When I started treating cases of melanoma that had metastasized to other organs, maybe 1 in 20 responded to treatment. Nobody in their right mind wanted to be a specialist in this field. It was the worst of the worst cancers.”
Dr. Goldberg was honored for his contribution to the understanding of vision loss and ways to reverse it. His lab has developed artificial retinas that transmit images down the optic nerve to the brain through tiny silicon chips implanted in the eye. He has also helped use imaging technology to better improve our ability to detect damage in photoreceptor cells (these are cells in the retina that are responsible for converting light into signals that are sent to the brain and that give us our color vision and night vision)
In a news release he expressed his gratitude saying: “I look forward to serving the goals of the National Academies, and to continuing my collaborative research efforts with my colleagues at the Byers Eye Institute at Stanford and around the world as we further our efforts to combat needless blindness.”
Dr. Anderson was honored for being a leader in the study of autoimmune diseases such as type 1 diabetes. This focus extends into the lab, where his research examines the genetic control of autoimmune diseases to better understand the mechanisms by which immune tolerance is broken.
Understanding what is happening with the immune system, figuring out why it essentially turns on the body, could one day lead to treatments that can stop that, or even reverse it by boosting immune activity.
Remember at the beginning I said that three and a half CIRM grantees were elected to the Academy, well, Canadian researcher, Dr. John Dick is the half. Why? Well, because the award we funded actually went to UC San Diego’s Dennis Carson but it was part of a Collaborative Funding Partnership Program with Dr. Dick at the University of Toronto. So, we are going to claim him as one of our own.
And he’s a pretty impressive individual to partner with. Dr. Dick is best known for developing a test that led to the discovery of leukemia stem cells. These are cells that can evade surgery, chemotherapy and radiation and which can lead to patients relapsing after treatment. His work helped shape our understanding of cancer and revealed a new strategy for curing it.
Two voices, one message, watch out for predatory stem cell clinics
Last week two new papers came out echoing each other about the dangers of bogus “therapies” being offered by predatory stem cell clinics and the risks they pose to patients.
The first was from the Pew Charitable Trusts entitled: ‘Harms Linked to Unapproved Stem Cell Interventions Highlight Need for Greater FDA Enforcement’ with a subtitle: ‘Unproven regenerative medical products have led to infections, disabilities, and deaths.’
That pretty much says everything you need to know about the report, and in pretty stark terms; need for greater FDA enforcement and infections, disabilities and deaths.
Just two days later, as if in response to the call for greater enforcement, the Food and Drug Administration (FDA) came out with its own paper titled: ‘Important Patient and Consumer Information About Regenerative Medicine Therapies.’ Like the Pew report the FDA’s paper highlighted the dangers of unproven and unapproved “therapies” saying it “has received reports of blindness, tumor formation, infections, and more… due to the use of these unapproved products.”
The FDA runs down a list of diseases and conditions that predatory clinics claim they can cure without any evidence that what they offer is even safe, let alone effective. It says Regenerative Medicine therapies have not been approved for the treatment of:
Arthritis, osteoarthritis, rheumatism, hip pain, knee pain or shoulder pain.
Blindness or vision loss, autism, chronic pain or fatigue.
Neurological conditions like Alzheimer’s and Parkinson’s.
Heart disease, lung disease or stroke.
The FDA says it has warned clinics offering these “therapies” to stop or face the risk of legal action, and it warns consumers: “Please know that if you are being charged for these products or offered these products outside of a clinical trial, you are likely being deceived and offered a product illegally.”
It tells consumers if you are offered one of these therapies – often at great personal cost running into the thousands, even tens of thousands of dollars – you should contact the FDA at firstname.lastname@example.org.
The Pew report highlights just how dangerous these “therapies” are for patients. They did a deep dive into health records and found that between 2004 and September 2020 there were more than 360 reported cases of patients experiencing serious side effects from a clinic that offered unproven and unapproved stem cell procedures.
Those side effects include 20 deaths as well as serious and even lifelong disabilities such as:
Partial or complete blindness (9).
Pulmonary embolism (6).
Heart attack (5).
Tumors, lesions, or other growths (16).
Organ damage or failure in several cases that resulted in death.
More than one hundred of the patients identified had to be hospitalized.
The most common type of procedures these patients were given were stem cells taken from their own body and then injected into their eye, spine, hip, shoulder, or knee. The second most common was stem cells from a donor that were then injected.
The Pew report cites the case of one California-based stem cell company that sold products manufactured without proper safety measures, “including a failure to properly screen for communicable diseases such as HIV and hepatitis B and C.” Those products led to at least 13 people being hospitalized due to serious bacterial infection in Texas, Arizona, Kansas, and Florida.
Shocking as these statistics are, the report says this is probably a gross under count of actual harm caused by the bogus clinics. It says the clinics themselves rarely report adverse events and many patients don’t report them either, unless they are so serious that they require medical intervention.
The Pew report concludes by saying the FDA needs more resources so it can more effectively act against these clinics and shut them down when necessary. It says the agency needs to encourage doctors and patients to report any unexpected side effects, saying: “devising effective strategies to collect more real-world evidence of harm can help the agency in its efforts to curb the growth of this unregulated market and ensure that the regenerative medicine field develops into one that clinicians and patients can trust and safely access.”
We completely support both reports and will continue to work with the FDA and anyone else opposed to these predatory clinics. You can read more here about what we have been doing to oppose these clinics, and here is information that will help inform your decision if you are thinking about taking part in a stem cell clinical trial but are not sure if it’s a legitimate one.
2020 has been, to say the very least, a difficult and challenging year for all of us. But while the focus of the world has, understandably, been on the coronavirus there was also some really promising advances in stem cell research. Those advances are captured in a great new documentary called Ending Disease.
The documentary is by Emmy award-winning filmmaker Joe Gantz. In it he follows ten people who are facing life-threatening or life-changing diseases and injuries and who turn to pioneering stem cell therapies for help.
It’s an inspiring documentary, one that reminds you of the real need for new treatments and the tremendous hope and promise of stem cell therapies. Here’s a look at a trailer for Ending Disease.
You can see an exclusive screening of Ending Disease on Friday, January 8th, 2021 at 5:00pm PST.
After the livestream, there will be a live Q&A session where former members of the successful Proposition 14 campaign team – which refunded CIRM with an additional $5.5 billion – will be joined by CIRM’s President and CEO Dr. Maria Millan, talking about what lies ahead for CIRM and the future of stem cell research.
To purchase a ticket, click here. It only costs $12 and 50% of the ticket sales proceeds will go to Americans for Cures to help them continue to advocate for the advancement of stem cell research, and more importantly, for the patients and families to whom stem cell research provides so much hope.
If you need any extra persuading that it’s something you should definitely put on our calendar, here’s a letter from the film maker Joe Gantz.
I am the director of the documentary Ending Disease: The Stem Cell, Anti-Cancer T-Cell, & Antibody Revolution In Medicine, a film that will help inform people about the progress that’s been made in this field and how people with their lives on the line are now able to benefit from these new regenerative therapies.
I was granted unprecedented access to ten of the first generation of clinical trials using stem cell and regenerative medicine to treat and cure many of the most devastating diseases and conditions including: brain cancer, breast cancer, leukemia and lymphoma, HIV, repairing a broken spinal cord, retinitis pigmentosa and SCID. The results are truly inspiring.
This is personal for me. After spending four years making this documentary, I was diagnosed with bladder cancer. Upon diagnosis, I immediately felt the same desperation as millions of families who are in search of a medical breakthrough. I understood, on a personal level, what the patients we followed in the film all knew: when you are diagnosed with a disease, there is a narrow window of time in which you can effectively seek a life-saving treatment or cure. If treatment becomes available outside of that window, then it is too late. However, Ending Disease shows that with continued support for regenerative medicine, we can create a near future in which one-time cures and highly mitigating therapies are available to patients for a whole host of diseases.
At CIRM we are modest enough to know that we can’t do everything by ourselves. To succeed we need partners. And in UC Davis we have a terrific partner. The work they do in advancing stem cell research is exciting and really promising. But it’s not just the science that makes them so special. It’s also their compassion and commitment to caring for patients.
What follows is an excerpt from an article by Lisa Howard on the work they do at UC Davis. When you read it you’ll see why we are honored to be a part of this research.
Gene therapy research at UC Davis
UC Davis’ commitment to stem cell and gene therapy research dates back more than a decade.
In 2010, with major support from the California Institute for Regenerative Medicine (CIRM), UC Davis launched the UC Davis Institute for Regenerative Cures, which includes research facilities as well as a Good Manufacturing Practice (GMP) facility.
Led by Jan Nolta, a professor of cell biology and human anatomy and the director of the UC Davis Institute for Regenerative Cures, the new center leverages UC Davis’ network of expert researchers, facilities and equipment to establish a center of excellence aimed at developing lifelong cures for diseases.
Nolta began her career at the University of Southern California working with Donald B. Kohn on a cure for bubble baby disease, a condition in which babies are born without an immune system. The blood stem cell gene therapy has cured more than 50 babies to date.
Work at the UC Davis Gene Therapy Center targets disorders that potentially can be treated through gene replacement, editing or augmentation.
“The sectors that make up the core of our center stretch out across campus,” said Nolta. “We work with the MIND Institute a lot. We work with the bioengineering and genetics departments, and with the Cancer Center and the Center for Precision Medicine and Data Sciences.”
A recent UC Davis stem cell study shows a potential breakthrough for healing diabetic foot ulcers with a bioengineered scaffold made up of human mesenchymal stem cells (MSCs). Another recent study revealed that blocking an enzyme linked with inflammation enables stem cells to repair damaged heart tissue. A cell gene therapy study demonstrated restored enzyme activity in Tay-Sachs disease affected cells in humanized mouse models.
“Some promising and exciting research right now at the Gene Therapy Center comes from work with hematopoietic stem cells and with viral vector delivery,” said Nolta.
Hematopoietic stem cells give rise to other blood cells. A multi-institutional Phase I clinical trial using hematopoietic stem cells to treat HIV-lymphoma patients is currently underway at UC Davis.
“We are genetically engineering a patient’s own blood stem cells with genes that block HIV infection,” said Joseph Anderson, an associate professor in the UC Davis Department of Internal Medicine. The clinical trial is a collaboration with Mehrdad Abedi, the lead principal investigator.
“When the patients receive the modified stem cells, any new immune system cell, like T-cell or macrophage, that is derived from one of these stem cells, will contain the HIV-resistant genes and block further infection,” said Anderson.
He explained that an added benefit with the unique therapy is that it contains an additional gene that “tags” the stem cells. “We are able to purify the HIV-resistant cells prior to transplantation, thus enriching for a more protective cell population.
Kyle David Fink
Kyle David Fink, an assistant professor of neurology at UC Davis, is affiliated with the Stem Cell Program and Institute for Regenerative Cures. His lab is focused on leveraging institutional expertise to bring curative therapies to rare, genetically linked neurological disorders.
“We are developing novel therapeutics targeted to the underlying genetic condition for diseases such as CDKL5 deficiency disorder, Angelman, Jordan and Rett syndromes, and Juvenile Huntington’s disease,” said Fink.
The lab is developing therapies to target the underlying genetic condition using DNA-binding domains to modify gene expression in therapeutically relevant ways. They are also creating novel delivery platforms to allow these therapeutics to reach their intended target: the brain.
“The hope is that these highly innovative methods will speed up the progress of bringing therapies to these rare neurodegenerative disease communities,” said Fink.

Developing potential lifetime cures
Among Nolta’s concerns is how expensive gene therapy treatments can be.
“Some of the therapies cost half a million dollars and that’s simply not available to everyone. If you are someone with no insurance or someone on Medicare, which reimburses about 65 percent, it’s harder for you to get these life-saving therapies,” said Nolta.
To help address that for cancer patients at UC Davis, Nolta has set up a team known as the “CAR T Team.”
Chimeric antigen receptor (CAR) T-cell therapy is a type of immunotherapy in which a patient’s own immune cells are reprogrammed to attack a specific protein found in cancer cells.
“We can develop our own homegrown CAR T-cells,” said Nolta. “We can use our own good manufacturing facility to genetically engineer treatments specifically for our UC Davis patients.”
Although safely developing stem cell treatments can be painfully slow for patients and their families hoping for cures, Nolta sees progress every day. She envisions a time when gene therapy treatments are no longer considered experimental and doctors will simply be able to prescribe them to their patients.
“And the beauty of the therapy is that it can work for the lifetime of a patient,” said Nolta.
Whenever you are designing something new you always have to keep in mind who the end user is. You can make something that works perfectly fine for you, but if it doesn’t work for the end user, the people who are going to work with it day in and day out, you have been wasting your time. And their time too.
At CIRM our end users are the patients. Everything we do is about them. Starting with our mission statement: to accelerate stem cell treatments to patients with unmet medical needs. Everything we do, every decision we make, has to keep the needs of the patient in mind.
So, when we were planning our recent 2020 Grantee Meeting (with our great friends and co-hosts UC Irvine and UC San Diego) one of the things we wanted to make sure didn’t get lost in the mix was the face and the voice of the patients. Often big conferences like this are heavy on science with presentations from some of the leading researchers in the field. And we obviously wanted to make sure we had that element at the Grantee meeting. But we also wanted to make sure that the patient experience was front and center.
And we did just that. But more on that in a minute. First, let’s talk about why the voice of the patient is important.
Some years ago, Dr. David Higgins, a CIRM Board member and patient advocate for Parkinson’s Disease (PD), said that when researchers are talking about finding treatments for PD they often focus on the dyskinesia, the trembling and shaking and muscle problems. However, he said if you actually asked people with PD you’d find they were more concerned with other aspects of the disease, the insomnia, anxiety and depression among other things. The key is you have to ask.
So, we asked some of our patient advocates if they would be willing to be part of the Grantee Meeting. All of them, without hesitation, said yes. They included Frances Saldana, a mother who lost three of her children to Huntington’s disease; Kristin MacDonald, who lost her sight to a rare disorder but regained some vision thanks to a stem cell therapy and is hoping the same therapy will help restore some more; Pawash Priyank, whose son Ronnie was born with a fatal immune disorder but who, thanks to a stem cell/gene therapy treatment, is now healthy and leading a normal life.
Because of the pandemic everything was virtual, but it was no less compelling for that. We interviewed each of the patients or patient advocates beforehand and those videos kicked off each session. Hearing, and seeing, the patients and patient advocates tell their stories set the scene for what followed. It meant that the research the scientists talked about took on added significance. We now had faces and names to highlight the importance of the work the scientists were doing. We had human stories. And that gave a sense of urgency to the work the researchers were doing.
But that wasn’t all. After all the video presentations each session ended with a “live” panel discussion. And again, the patients and patient advocates were a key part of that. Because when scientists talk about taking their work into a clinical trial they need to know if the way they are setting up the trial is going to work for the patients they’re hoping to recruit. You can have the best scientists, the most promising therapy, but if you don’t design a clinical trial in a way that makes it easy for patients to be part of it you won’t be able to recruit or retain the people you need to test the therapy.
Patient voices count. Patient stories count.
But more than anything, hearing and seeing the people we are trying to help reminds us why we do this work. It’s so easy to get caught up in the day to day business of our jobs, struggling to get an experiment to work, racing to get a grant application in before the deadline. Sometimes we get so caught up in the minutiae of work we lose sight of why we are doing it. Or who we are doing it for.
At CIRM we have a saying; come to work every day as if lives depend on you, because lives depend on you. Listening to the voices of patients, seeing their faces, hearing their stories, reminds us not to waste a moment. Because lives depend on all of us.
Here’s one of the interviews that was featured at the event. I do apologize in advance for the interviewer, he’s rubbish at his job.
Over 650,000 Americans suffer from end-stage kidney disease – a life-threatening condition caused by the loss of kidney function. The best available treatment for these patients is a kidney transplant from a genetically matched living donor. However, patients who receive a transplant must take life-long immunosuppressive drugs to prevent their immune system from rejecting the transplanted organ. Over time, these drugs are toxic and can increase a patient’s risk of infection, heart disease, cancer and diabetes. Despite these drugs, many patients still lose transplanted organs due to rejection.
To tackle this problem Medeor is developing a stem cell-based therapy called MDR-101. This is being tested in a Phase 3 clinical trial and it’s hoped it will eliminate the need for immunosuppressive drugs in genetically matched kidney transplant patients.
The company takes blood-forming stem cells and immune cells from the organ donor and infuses them into the patient receiving the donor’s kidney. Introducing the donor’s immune cells into the patient creates a condition called “mixed chimerism” where immune cells from the patient and the donor are able to co-exist. In this way, the patient’s immune system is able to adapt to and tolerate the donor’s kidney, potentially eliminating the need for the immunosuppressive drugs that are normally necessary to prevent transplant rejection.
So how does getting RMAT designation help that? Well, the FDA created the RMAT program to help speed up the development and review of regenerative medicine therapies that can treat, modify, reverse, or cure a serious condition. If MDR-101shows it is both safe and effective RMAT could help it get faster approval for wider use.
In a news release Giovanni Ferrara, President and CEO of Medeor, welcomed the news.
“This important designation underscores the tremendous unmet medical need for alternatives to today’s immunosuppressive therapies for transplantation. We have the potential to help people live longer, healthier lives without the need for high dose and chronic immunosuppression and we thank the FDA for this designation that will assist us progressing as efficiently as possible toward a commercially available product.”
