Stem Cell Therapy During Pregnancy May Prevent Serious Birth Defect, Study Finds

Summary:

A new medical study suggests that stem cell therapy performed on unborn babies during pregnancy may help treat spina bifida, a serious birth defect affecting the spine and brain. Researchers say the experimental procedure showed promising results in early clinical trials.

Key Points

• Researchers tested stem cell therapy on unborn babies with spina bifida.
• The therapy was applied during fetal surgery to repair the spinal cord.
• The study involved six pregnant women between 24 and 25 weeks of pregnancy.
• MRI scans after birth showed significant improvement in brain structure.
• Scientists believe the therapy could reduce lifelong neurological complications.

Detailed Article:

A new medical study has suggested that stem cell therapy performed during pregnancy may help treat spina bifida, a serious birth defect that affects the development of a baby’s spine and nervous system.

Spina bifida occurs when the spinal cord does not form properly in the womb. The condition is usually detected during pregnancy or shortly after birth and can lead to severe complications, including paralysis, difficulty walking, loss of sensation in the legs, and problems controlling bladder or bowel functions.

In the study, surgeons performed fetal surgery to repair the spinal cord and applied stem cells directly to the affected area. The researchers believe that this additional step could significantly improve long-term health outcomes for affected children.

The clinical trial was conducted in California and involved six pregnant women who were between 24 and 25 weeks into their pregnancies. All of the babies had been diagnosed with myelomeningocele, a severe form of open spina bifida, along with a related brain condition known as hindbrain herniation.

During the surgery, doctors repaired the spinal defect and also applied stem cells derived from donated placental tissue directly onto the spinal cord.

The six babies were born between July 2021 and December 2022, and doctors reported that all of them had properly repaired spinal cords without signs of infection or abnormal tissue growth.

MRI scans performed after birth confirmed that the hindbrain herniation had completely resolved and the brain had returned to a normal position.

Researchers say the results are promising and could lead to new treatment options for preventing lifelong neurological complications caused by spina bifida.
