Using cells from sheep’s amniotic fluid, researchers have constructed tracheas for fetal lambs that can be used to repair congenitally malformed ones.
The Children’s Hospital Boston team reported Thursday at an American Academy of Pediatrics meeting that they collected mesenchymal stem cells, grew them in culture, then seeded them onto a tube-shaped scaffolding. Prenatal lambs receiving the tracheas were able to breathe normally at birth. Researchers hope to begin tests in humans soon.
