Derivation of primary fetal epithelial organoids from cryopreserved human amniotic fluid cells.

Key takeaways

Researchers grew tiny lab models of human tissue, called organoids, from cells floating in amniotic fluid around a fetus. The fluid had been frozen and thawed first, and the cells still grew into kidney, lung and gut tissue. This offers a way to study fetal kidney tissue without needing tissue from ended pregnancies. It was done in the lab only, not in people, and it is an early report that other scientists have not yet reviewed.
