Scientists say groundbreaking method could lead to human gestation outside the womb; new insight into organ formation could spur other advances; fetuses have fully formed organs.
Israeli scientists have grown 250-cell embryos into mouse fetuses with fully formed organs using artificial wombs, in a development they say could pave the way for gestating humans outside the womb.
“We have grown hundreds of mice in this way, in a method that has taken seven years to develop, and I’m still captivated every time I see it,” stem cell biologist Prof. Jacob Hanna of the Weizmann Institute of Science told The Times of Israel.
