The fetal surgeons then closed the incision to allow the tissue to regenerate. The team declared the first-of-its-kind surgery a success. Then, the stem cell patch was placed directly over the exposed spinal cord of the fetus. The Procedureĭuring 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. It is here that they made the stem cell patch for Emily’s fetal surgery. The lab is a Good Manufacturing Practice (GMP) Laboratory for safe use in humans. Her fetal surgery was scheduled for July 12, 2021, at 25 weeks and five days gestation.įarmer 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. 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.Īfter screenings, MRI scans and interviews, Emily received the news that she was accepted into the trial. 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. When Emily and her husband Harry learned that they would be first-time parents, they never expected any pregnancy complications. 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. Over that time, animal modeling has shown it is capable of preventing the paralysis associated with spina bifida. Together, they researched and tested ways to use stem cells and bioengineering to advance the effectiveness and outcomes of the surgery.įarmer, Wang and their research team have been working on their novel approach using stem cells in fetal surgery for more than 10 years.

Many children in that study showed improvement but still required wheelchairs or leg braces. In previous clinical trial, Farmer had helped to prove that fetal surgery reduced neurological deficits from spina bifida. Diana Farmer, the world’s first woman fetal surgeon, professor and chair of surgery at UC Davis Health and principal investigator on the study. “I’ve been working toward this day for almost 25 years now,” said Dr. 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. The first phase of the trial is funded by a $9 million grant from the California Institute for Regenerative Medicine. The story was featured in BBC News and The Sacramento Bee. 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. 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. The California Institute for Regenerative Medicine (CIRM) recently shared some encouraging news on The Stem Cellar about a CIRM-funded stem cell clinical trial for spina bifida at UC Davis Health. Diana Farmer (right) meets with Emily Lofton and her baby Robbie who had stem cell treatment for spina bifida in the womb.
