Fetal stem cells aim to mend broken bones in infants

NCT ID NCT03706482

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This early-phase trial tests whether fetal stem cells given before or after birth can safely help infants with severe osteogenesis imperfecta, a genetic condition causing fragile bones and frequent fractures. Up to 18 children will receive multiple doses of the cells. The main goal is to check safety, but researchers will also track fracture rates and bone density.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

fetal liver-derived mesenchymal stem cells (BOOST cells)

What this could lead to

If it works, this could point toward a treatment that reduces fractures and improves bone strength in children with severe brittle bone disease.

What could go wrong

This is a very early, small trial (18 participants) focused mainly on safety. The cells may cause immune reactions or fail to improve bone health, and long-term effects are unknown.
