Michelle y Jeff se llenaron de felicidad cuando se enteraron de que iban a tener un bebé.
Luego, un examen de ultrasonido a las 20 semanas del embarazo reveló que el feto tenía espina bífida, una malformación congénita que ocurre cuando la columna vertebral y la médula espinal no se forman de manera adecuada. La espina bífida puede causar parálisis y otras complicaciones serias.
Se derivó a la pareja a un ensayo clínico en la Universidad de California, Davis, que lleva a cabo la Dra. Diana Farmer, cirujana fetal y neonatal reconocida a nivel internacional, y su colega, el Dr. Aijun Wang.
En este ensayo clínico, que se basó en una previa investigación financiada por el CIRM, se repara el defecto espinal aplicando células madre de una placenta donada, las cuales se insertan en una estructura sintética y se aplican al defecto de la médula espinal mientras el bebé se encuentra todavía en el útero.
El hijo de Michelle y Jeff, Tobi, fue el segundo paciente que recibió este tratamiento. Michelle dijo que la cirugía fue difícil, pero el nacimiento de su bebé valió la pena.
“Cuando lo abrazamos por primera vez dijimos, ‘No puedo creer que hayamos hecho esto. Lo logramos. Lo hicimos sin saber si funcionaría’.”
A los tres meses, el progreso de Tobi parece promisorio. Jeff y Michelle saben que pueden surgir problemas más adelante, pero por ahora se sienten agradecidos de haber formado parte de este ensayo.
Spina bifida is a birth defect that occurs when the spine and spinal cord don’t form properly and can result in life-long walking and mobility problems for the child, even paralysis.
Now, UC Davis has released more details about the clinical trial and the babies born after receiving the world’s first spina bifida treatment combining surgery with stem cells. The story was featured in BBC News and The Sacramento Bee.
The first phase of the trial is funded by a $9 million grant from the California Institute for Regenerative Medicine.
The one-of-a-kind treatment, delivered while a fetus is still developing in the mother’s womb, could improve outcomes for children with this birth defect.
A Decade’s Work
“I’ve been working toward this day for almost 25 years now,” said Dr. Diana Farmer, the world’s first woman fetal surgeon, professor and chair of surgery at UC Davis Health and principal investigator on the study.
In previous clinical trial, Farmer had helped to prove that fetal surgery reduced neurological deficits from spina bifida. Many children in that study showed improvement but still required wheelchairs or leg braces.
Farmer recruited bioengineer Dr. Aijun Wang to help take that work to the next level. Together, they researched and tested ways to use stem cells and bioengineering to advance the effectiveness and outcomes of the surgery.
Farmer, Wang and their research team have been working on their novel approach using stem cells in fetal surgery for more than 10 years. Over that time, animal modeling has shown it is capable of preventing the paralysis associated with spina bifida.
Preliminary work by Farmer and Wang proved that prenatal surgery combined with human placenta-derived mesenchymal stromal cells, held in place with a biomaterial scaffold to form a “patch,” helped lambs with spina bifida walk without noticeable disability. When the team refined their surgery and stem cells technique for canines, the treatment also improved the mobility of dogs with naturally occurring spina bifida.
The CuRe Trial
When Emily and her husband Harry learned that they would be first-time parents, they never expected any pregnancy complications. But the day that Emily learned that her developing child had spina bifida was also the day she first heard about the CuRe trial, as the clinical trial is known.
Participating in the trial would mean that she would need to temporarily move to Sacramento for the fetal surgery and then for weekly follow-up visits during her pregnancy.
After screenings, MRI scans and interviews, Emily received the news that she was accepted into the trial. Her fetal surgery was scheduled for July 12, 2021, at 25 weeks and five days gestation.
Farmer and Wang’s team manufactured clinical grade stem cells—mesenchymal stem cells—from placental tissue in the UC Davis Health’s CIRM-funded Institute for Regenerative Cures. The lab is a Good Manufacturing Practice (GMP) Laboratory for safe use in humans. It is here that they made the stem cell patch for Emily’s fetal surgery.
During Emily’s historic procedure, a small opening was made in her uterus and they floated the fetus up to that incision point so they could expose its spine and the spina bifida defect.
Then, the stem cell patch was placed directly over the exposed spinal cord of the fetus. The fetal surgeons then closed the incision to allow the tissue to regenerate. The team declared the first-of-its-kind surgery a success.
On Sept. 20, 2021, at 35 weeks and five days gestation, Robbie was born at 5 pounds, 10 ounces, 19 inches long via C-section.
For Farmer, this day is what she had long hoped for, and it came with surprises. If Robbie had remained untreated, she was expected to be born with leg paralysis.
“It was very clear the minute she was born that she was kicking her legs and I remember very clearly saying, ‘Oh my God, I think she’s wiggling her toes!’” said Farmer. “It was amazing. We kept saying, ‘Am I seeing that? Is that real?’”
Both mom and baby are at home and in good health. Robbie just celebrated her first birthday.
The CuRe team is cautious about drawing conclusions and says a lot is still to be learned during this safety phase of the trial. The team will continue to monitor Robbie and the other babies in the trial until they are 6 years old, with a key checkup happening at 30 months to see if they are walking and potty training.
“This experience has been larger than life and has exceeded every expectation. I hope this trial will enhance the quality of life for so many patients to come,” Emily said. “We are honored to be part of history in the making.”

It’s hard to think of something as being rare when it affects up to 30 million Americans and 300 million people worldwide. But the truth is there are more than 6,000 conditions – those affecting 200,000 people or fewer – that are considered rare.
Today, February 28th, is Rare Disease Day. It’s a day to remind ourselves of the millions of people, and their families, struggling with these diseases. These conditions are also called or orphan diseases because, in many cases, drug companies were not interested in adopting them to develop treatments.
At the California Institute for Regenerative Medicine (CIRM), we have no such reservations. In fact last Friday our governing Board voted to invest almost $12 million to support a clinical trial for IPEX syndrome. IPEX syndrome is a condition where the body can’t control or restrain an immune response, so the person’s immune cells attack their own healthy tissue. This leads to the development of Type 1 diabetes, severe eczema, damage to the small intestines and kidneys and failure to thrive. It’s diagnosed in infancy, most of those affected are boys, and it is often fatal.
IPEX is one of two dozen rare diseases that CIRM is funding a clinical trial for. In fact, more than one third of all the projects we fund target a rare disease or condition. Those include:
Some might question the wisdom of investing hundreds of millions of dollars in conditions that affect a relatively small number of patients. But if you see the faces of these patients and get to know their families, as we do, you know that often agencies like CIRM are their only hope.
Dr. Maria Millan, CIRM’s President and CEO, says the benefits of one successful approach can often extend far beyond one rare disease.
“Children with IPEX syndrome clearly represent a group of patients with an unmet medical need, and this therapy could make a huge difference in their lives. Success of this treatment in this rare disease presents far-reaching potential to develop treatments for a larger number of patients with a broad array of immune disorders.”
CIRM is proud to fund and spread awareness of rare diseases and invites you to watch this video about how they affect families around the world.
It’s appropriate that at the start of Women’s History Month, UC Davis’ Dr. Diana Farmer is making a little history of her own. She launched the world’s first clinical trial using stem cells to treat spina bifida before the child is born.
Spina bifida is a birth defect caused when a baby’s spinal cord fails to develop properly in the womb. In myelomeningocele, the most severe form of spina bifida, a portion of the spinal cord or nerves is exposed in a sac through an opening in the spine. Most people with myelomeningocele have changes in their brain structure, leg weakness, and bladder and bowel dysfunction.
While surgery can help, Dr. Farmer says it is far from perfect: “Currently, the standard of care for our patients is fetal surgery, which, while promising, still leaves more than half of children with spina bifida unable to walk independently. There is an extraordinary need for a treatment that prevents or lessens the severity of this devastating condition. Our team has spent more than a decade working up to this point of being able to test such a promising therapy.”
The team at UC Davis – in a CIRM-funded study – will use a stem cell “patch” that is placed over the exposed spinal cord, then surgically close the opening, hopefully allowing the stem cells to regenerate and protect the spinal cord.
In a news release Dr. Aijun Wang, a stem cell bioengineer, says the team has been preparing for this trial for years, helping show in animals that it is safe and effective. He is hopeful it will prove equally safe and effective in people: “Our cellular therapy approach, in combination with surgery, should encourage tissue regeneration and help patients avoid devastating impairments throughout their lives.”
Dr. Farmer says the condition, while rare, disproportionately affects Latinx babies and if the procedure works could have an enormous impact on their lives and the lives of their families: “A successful treatment for MMC would relieve the tremendous emotional and economic cost burden on families. We know it initially costs approximately $532,000 per child with spina bifida. But the costs are likely several million dollars more due to ongoing treatments, not to mention all the pain and suffering, specialized childcare, and lost time for unpaid caregivers such as parents.”
Here is video of two English bulldogs who had their spinal injuries repaired at UC Davis using stem cells. This was part of the research that led to the clinical trial led by Dr. Farmer and Dr. Wang.
All this month we are using our blog and social media to highlight a new chapter in CIRM’s life, thanks to the voters approving Proposition 14. We are looking back at what we have done since we were created in 2004, and also looking forward to the future.Today we feature a blog written by two of our fabulous Discovery and Translation team Science Officers, Dr. Kent Fitzgerald and Dr. Ross Okamura.
If you believe that you can know a person by their deeds, the partnership opportunities offered by CIRM illustrate what we, as an agency, believe is the most effective way to deliver on our mission statement, accelerating regenerative medicine treatments to patients with unmet medical needs.
In our past, we have offered awards covering basic biology projects which in turn provided the foundation to produce promising therapies to ease human suffering. But those are only the first steps in an elaborate process.
In order to bring these potential therapies to the clinic, selected drug candidates must next go through a set of activities designed to prepare them for review by the Food and Drug Administration (FDA). For cell therapies, the first formal review is often the Pre- Investigational New Drug Application Consultation or pre-IND. This stage of drug development is commonly referred to as Translational, bridging the gap between our Discovery or early stage research and Clinical Trial programs.
One of our goals at CIRM is to prepare Translational projects we fund for that pre-IND meeting with the FDA, to help them gather data that support the hope this approach will be both safe and effective in patients. Holding this meeting with the FDA is the first step in the often lengthy process of conducting FDA regulated clinical trials and hopefully bringing an approved therapy to patients.
What type of work is required for a promising candidate to move from the Discovery stage into FDA regulated development? To address the needs of Translational science, CIRM offers the Translational Research Project funding opportunity. Activities that CIRM supports at the Translational stage include:
Process Development to allow manufacturing of the candidate therapy under Good Manufacturing Practices (GMP). This is to show that they can manufacture at a large enough scale to treat patients.
Assay development and qualification of measurements to determine whether the drug is being manufactured safely while retaining its curative properties.
Studies to determine the optimal dose and the best way to deliver that dose.
Pilot safety studies looking how the patient might respond after treatment with the drug.
The development of a clinical plan indicating under what rules and conditions the drug might be prescribed to a patient.
These, and other activities supported under our Translational funding program, all help to inform the FDA when they consider what pivotal studies they will require prior to approving an Investigational New Drug (IND) application, the next step in the regulatory approval process.
Since CIRM first offered programs specifically aimed at addressing the Translational stage of therapeutic candidates we have made 41 awards totaling approximately $150 million in funding. To date, 13 have successfully completed and achieved their program goals, while 19 others are still actively working towards meeting their objective. Additionally, three (treating Spina Bifida, Osteonecrosis, and Sickle Cell Disease) of the 13 programs have gone on to receive further CIRM support through our Clinical Stage programs.
During our time administering these awards, CIRM has actively partnered with our grantees to navigate what is required to bring a therapy from the bench to the bedside. CIRM operationalizes this by setting milestones that provide clear definitions of success, specific goals the researchers have to meet to advance the project and also by providing resources for a dedicated project manager to help ensure the project can keep the big picture in mind while executing on their scientific progress.
Throughout all this we partner with the researchers to support them in every possible way. For example, CIRM provides the project teams with Translational Advisory Panels (TAPs, modeled after the CIRM’s Clinical Advisory Panels) which bring in outside subject matter experts as well as patient advocates to help provide additional scientific, regulatory and clinical expertise to guide the development of the program at no additional cost to the grantees. One of the enduring benefits that we hope to provide to researchers and organizations is a practical mastery of translational drug development so that they may continue to advance new and exciting therapies to all patients.
Through CIRM’s strong and continued support of this difficult stage of development, CIRM has developed an internal practical expertise in advancing projects through Translation. We employ our experience to guide our awardees so they can avoid common pitfalls in the development of cell and gene therapies. The end goal is simple, helping to accelerate their path to the clinic and fulfilling the mission of CIRM that has been twice given to us by the voters of California, bringing treatments to patients suffering from unmet medical needs.
This past Thursday the governing Board of the California Institute for Regenerative Medicine (CIRM) approved four new clinical trials in addition to ten new discovery research awards.
These new awards bring the total number of CIRM-funded clinical trials to 68. Additionally, these new additions have allowed the state agency to exceed the goal of commencing 50 new trials outlined in its five year strategic plan.
$8,970,732 was awarded to Dr. Steven Deeks at the University of California San Francisco (UCSF) to conduct a clinical trial that modifies a patient’s own immune cells in order to treat and potentially cure HIV.
Current treatment of HIV involves the use of long-term antiretroviral therapy (ART). However, many people are not able to access and adhere to long-term ART.
Dr. Deeks and his team will take a patient’s blood and extract T cells, a type of immune cell. The T cells are then genetically modified to express two different chimeric antigen receptors (CAR), which enable the newly created duoCAR-T cells to recognize and destroy HIV infected cells. The modified T cells are then reintroduced back into the patient.
The goal of this one time therapy is to act as a long-term control of HIV with patients no longer needing to take ART, in effect a form of HIV cure. This approach would also address the needs of those who are not able to respond to current approaches, which is estimated to be 50% of those affected by HIV globally.
$3,728,485 was awarded to Dr. Gayatri Rao from Rocket Pharmaceuticals to conduct a clinical trial using a gene therapy for infantile malignant osteopetrosis (IMO), a rare and life-threatening disorder that develops in infancy. IMO is caused by defective bone cell function, which results in blindness, deafness, bone marrow failure, and death very early in life.
The trial will use a gene therapy that targets IMO caused by mutations in the TCIRG1 gene. The team will take a young child’s own blood stem cells and inserting a functional version of the TCIRG1 gene. The newly corrected blood stem cells are then introduced back into the child, with the hope of halting or preventing the progression of IMO in young children before much damage can occur.
Rocket Pharmaceuticals has used the same gene therapy approach for modifying blood stem cells in a separate CIRM funded trial for a rare pediatric disease, which has shown promising results.
$8,996,474 was awarded to Dr. Diana Farmer at UC Davis to conduct a clinical trial of in utero repair of myelomeningocele (MMC), the most severe form of spina bifida. MMC is a birth defect that occurs due to incomplete closure of the developing spinal cord, resulting in neurological damage to the exposed cord. This damage leads to lifelong lower body paralysis, and bladder and bowel dysfunction.
Dr. Farmer and her team will use placenta tissue to generate mesenchymal stem cells (MSCs). The newly generated MSCs will be seeded onto an FDA approved dural graft and the product will be applied to the spinal cord while the infant is still developing in the womb. The goal of this therapy is to help promote proper spinal cord formation and improve motor function, bladder function, and bowel function.
$8,333,581 was awarded to Dr. David Williams at Boston Children’s Hospital to conduct a gene therapy clinical trial for sickle cell disease (SCD). This is the second project that is part of an agreement between CIRM and the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, to co-fund cell and gene therapy programs under the NHLBI’s “Cure Sickle Cell” Initiative. The goal of this agreement is to markedly accelerate clinical development of cell and gene therapies to cure SCD.
SCD is an inherited disease caused by a single gene mutation resulting in abnormal hemoglobin, which causes red blood cells to ‘sickle’ in shape. Sickling of red blood cells clogs blood vessels and leads to progressive organ damage, pain crises, reduced quality of life, and early death.
The team will take a patient’s own blood stem cells and insert a novel engineered gene to silence abnormal hemoglobin and induce normal fetal hemoglobin expression. The modified blood stem cells will then be reintroduced back into the patient. The goal of this therapy is to aid in the production of normal shaped red blood cells, thereby reducing the severity of the disease.
“Today is a momentus occasion as CIRM reaches 51 new clinical trials, surpassing one of the goals outlined in its five year strategic plan,” says Maria T. Millan, M.D., President and CEO of CIRM. “These four new trials, which implement innovative approaches in the field of regenerative medicine, reflect CIRM’s ever expanding and diverse clinical portfolio.”
The Board also approved ten awards that are part of CIRM’s Quest Awards Prgoram (DISC2), which promote promising new technologies that could be translated to enable broad use and improve patient care.
The awards are summarized in the table below:

Every so often you hear a story and your first reaction is “oh, I have to share this with someone, anyone, everyone.” That’s what happened to me the other day.
I was talking with Kristin MacDonald, an amazing woman, a fierce patient advocate and someone who took part in a CIRM-funded clinical trial to treat retinitis pigmentosa (RP). The disease had destroyed Kristin’s vision and she was hoping the therapy, pioneered by jCyte, would help her. Kristin, being a bit of a pioneer herself, was the first person to test the therapy in the U.S.
Anyway, Kristin was doing a Zoom presentation and wanted to look her best so she asked a friend to come over and do her hair and makeup. The woman she asked, was Rosie Barrero, another patient in that RP clinical trial. Not so very long ago Rosie was legally blind. Now, here she was helping do her friend’s hair and makeup. And doing it beautifully too.
That’s when you know the treatment works. At least for Rosie.
There are many other stories to be heard – from patients and patient advocates, from researchers who develop therapies to the doctors who deliver them. – at our CIRM 2020 Grantee Meeting on next Monday September 14th Tuesday & September 15th.
It’s two full days of presentations and discussions on everything from heart disease and cancer, to COVID-19, Alzheimer’s, Parkinson’s and spina bifida. Here’s a link to the Eventbrite page where you can find out more about the event and also register to be part of it.
Like pretty much everything these days it’s a virtual event so you’ll be able to join in from the comfort of your kitchen, living room, even the backyard.
And it’s free!
You can join us for all two days or just one session on one day. The choice is yours. And feel free to tell your friends or anyone else you think might be interested.
Some of you might remember a movie in the early 2000s by the name of “Miracle in Lane 2”. The film is based on an inspirational true story and revolves around a boy named Justin Yoder entering a soapbox derby competition. In the movie, Justin achieves success as a soapbox derby driver while adapting to the challenges of being in a wheelchair.
The reason that Justin is unable to walk is due to a birth defect known as spina bifida, which causes an incomplete closing of the backbone portion of the spinal cord, exposing tissue and nerves. In addition to difficulties with walking, other problems associated with this condition are problems with bladder or bowel control and accumulation of fluid in the brain.
According to the Center for Disease Control (CDC) , each year about 1,645 babies in the US are born with spina bifida, with Hispanic women having the highest rate of children born with the condition. There is currently no cure for this condition, but researchers at UC Davis are one step closer to changing that.
Dr. Aijun Wang, Dr. Diana Farmer, and their research team have identified crucial byproducts produced by stem cells that play an important role in protecting neurons. These byproducts could assist with improving lower-limb motion in patients with spina bifida.
Prior to this discovery, Dr. Farmer and Dr. Wang demonstrated that prenatal surgery combined with connective tissue (e.g. stromal cells) derived from stem cells improved hind limb control in dogs with spina bifida. Below you can see a clip of two English bulldogs with spina bifida who are now able to walk.
By any standards Dr. Diana Farmer is a determined woman who doesn’t let setbacks and failure deter her. As a fetal and neonatal surgeon, and the chair of the Department of Surgery at UC Davis Health, Dr. Farmer has spent years trying to develop a cure for spina bifida. She’s getting closer.
Dr. Farmer and her partner in this research, Dr. Aijun Wang, have already shown they can repair the damage spina bifida causes to the spinal cord, in the womb, in sheep and bulldogs. Last year the CIRM Board voted to fund her research to get the data needed to apply to the US Food and Drug Administration for permission to start a clinical trial in people.
That work is so promising that we decided to profile Dr. Farmer in our 2018 Annual Report.
Here’s excerpts from an interview we conducted with her as part of the Annual Report.
I have been working on this since 2008. We have been thinking about how to help kids with spina bifida walk. It’s not fatal disease but it is a miserable disease.
It’s horrible for parents who think they are about to have a healthy child suddenly be faced with a baby who faces a life long struggle with their health, everything from difficulty or inability to walk to bowel and bladder problems and life-threatening infections.
As a fetal surgeon we used to only focus on fatal diseases because otherwise kids would die. But as we made progress in the field, we had the opportunity to help others who didn’t have a fatal condition, in ways we couldn’t have done in the past.
I’ve always been fascinated by the placenta, it has lots of protective properties. So, we asked the question if we were able to sample fetal cells from the placenta, could we augment those cells, and use them to tissue engineer spinal injuries, in the womb, to improve the outcome for kids with spina bifida?
Dr. Aijun Wang and I have been working on this project for the last decade. Ten years of work has taken us to this point where we are now ready to move this to the next level.
It’s amazing to me how long this process takes and that’s why we are so grateful to CIRM because this is a rare disease and finding funding for those is hard. A lot of people are scared about funding fetal surgery and CIRM has been a perfect partner in helping bring this approach, blending stem cell therapy and tissue engineering, together.
If this therapy is successful it will have a huge economic impact on California, and on the rest of the world. Because spina bifida is a lifelong condition involving many operations, many stays in the hospital, in some cases lifelong use of a wheelchair. This has a huge financial burden on the family. And because this doesn’t just affect the child but the whole family, it has a huge psychological burden on families. It affects them in so many ways; parents having to miss work or take time off work to care for their child, other children in the family feeling neglected because their brother or sister needs so much attention.
In the MOMS Trial (a study that looked at prenatal – before birth – and postnatal – after birth – surgery to repair a defect in the spinal cord and showed that prenatal surgery had strong, long-term benefits and some risks) we showed that we could operate on the fetus before birth and help them. The fact that there was any improvement – doubling the number of kids who could walk from 20 to 40% showed this spinal cord injury is not a permanent situation and also showed there was some plasticity in the spinal cord, some potential for improvement. And so, the next question was can we do more. And that’s why we are trying this.
It’s pretty amazing. We are pretty excited.
The thing that makes surgeon-scientists feel so passionate is that we don’t just ask the fundamental questions, we ask questions in order to cure a problem in patients. I grew up in an environment where people were always asking “how can we do it better, how can we improve?”
There were many times of frustration, many times when cell types we explored and worked with didn’t work. But it’s the patients, seeing them, that keeps me motivated to do the science, to keep persevering. That’s the beauty of being a clinician-scientist. We can ask questions in a different way and look at data in a different way because we are driven by patient outcomes. So, whenever we get stuck in the rabbit hole of theoretical problems, we look to the patients for inspiration to keep going.
I am very cognizant of stirring up false hope, knowing that what occurs in animal models doesn’t always translate into humans. But we are optimistic, and I am anxious to get going.
Every day in the U.S. four children are born with spina bifida. It is the most common cause of lifelong paralysis and also frequently leads to other serious health problems affecting the bowel and bladder. The impact on families is enormous. A new approach to repairing the defect that causes spina bifida was today awarded $5.66 million by the Board of the California Institute for Regenerative Medicine (CIRM).
In spina bifida the spinal cord doesn’t form properly, in many cases leaving a section of it open, exposing tissues and nerves. The current standard of care is surgery, but even this leaves almost 60% of children unable to walk independently. Diana Farmer MD, and Aijun Wang PhD at U.C. Davis will use mesenchymal stem cells, taken from a donor placenta, and place them on a form of synthetic scaffold over the injury site in the womb. Tests in animals show this approach was able to repair the defect and prevent paralysis.
“Spina bifida is a devastating condition for babies born with this disorder and the families who care for them,” says Maria T. Millan, MD, President & CEO of CIRM. “CIRM has funded this important work from its earliest stages and we are committed to working with Dr. Farmer’s team to moving this work to the stage where it can be tested in patients.”
The CLIN1 award will provide funding to enable the UC Davis team to do the final testing and preparations needed to apply to the FDA for permission to start a clinical trial.
Dr. Farmer says she and Dr. Wang, have been working on this approach for more than ten years and are excited about being able to take the next step.
“There were many times of frustration, many times when cell types we explored and worked with didn’t work,” says Dr. Farmer. “But it’s the patients, seeing them, talking to them and working with them, that keeps me motivated to do the science, to keep persevering.”
If this therapy is successful it will have a huge economic impact on California, and on the rest of the world. Because spina bifida is a lifelong condition involving many operations, many stays in the hospital and, in some cases, lifelong use of a wheelchair this has a huge financial, and psychological, burden on the family.
“It affects them in so many ways; parents having to miss work or take time off work to care for their child, other children in the family feeling neglected because their brother or sister needs so much attention,” says Dr. Farmer. “That’s why we are so grateful to CIRM. Because this is a rare disease and finding funding for those is hard. CIRM has been a perfect partner in helping bring this approach, blending stem cell therapy and tissue engineering, together to help these families.”
