With innovative bioreactor as womb, mouse stem cells transform into organ-filled embryos

Published on August 3, 2022

Researchers have opened a new window in the process of embyonic development. They’ve made artificial mouse embryos from stem cells—no sperm or eggs required—and used an innovative bioreactor to nurture their creations for longer than any previous embryo models. This may allow biologists to better understand what goes wrong in birth defects.
