Helping spinal bone grow before birth in babies with spina bifida

Engineering the fetal environment for in utero treatment of spina bifida bone defect

NIH-funded research University of California at Davis · NIH-11307635

What this research studies

If my fetus has myelomeningocele (the most severe spina bifida), researchers plan to add placental mesenchymal stem cells to the current in utero repair and use the fetal environment to encourage vertebrae to regenerate. Prior work in fetal sheep showed the stem cells protect the spinal cord and prevent paralysis at birth, but the animals later developed spinal deformities because the vertebral bone did not regrow. This effort focuses on stimulating endogenous fetal cells and engineering the fetal environment so the bony spine can form and support the repaired cord long-term. The goal is to combine surgical repair with biological and tissue-support strategies that create durable bone support before birth.

Who could benefit from this research

Good fit: Pregnant people carrying fetuses diagnosed with myelomeningocele (severe spina bifida) who are candidates for in utero surgical repair would be the ideal participants in future clinical testing.

Not a fit: Pregnancies with milder forms of spina bifida, diagnoses made too late in gestation, or maternal/fetal conditions that make fetal surgery unsafe would likely not benefit from this approach.

Why it matters

Potential benefit: If successful, this could protect the repaired spinal cord, reduce spinal deformities like kyphosis, and preserve long-term motor function in children born with severe spina bifida.

How similar studies have performed: Related preclinical work showed placental stem cells prevented hindlimb paralysis at birth in a fetal sheep model, but durable bone regeneration is a newer, still-unproven addition.
