Researchers announce the development of a mouse embryo model, complete with beating hearts and the foundations for a brain and other organs, out of mouse embryonic stem cells. Just two weeks after ...

The tiny mouse embryo has a heart that beats. Its muscles, blood vessels, gut and nervous system are beginning to develop. But this embryo is unusual: It was made in a lab, out of mouse embryonic stem ...

Researchers from the University of Cambridge and Caltech have created model mouse embryos from stem cells—the body's master cells, which can develop into almost any cell type in the body—that have ...

Scientists in Israel are now one step closer to growing human organs in a laboratory thanks to mouse embryos. They successfully grew synthetic mouse embryos without using sperm, eggs, or a womb.

A video showing a synthetic mouse embryo model on day 8 of its development; it has a beating heart, a yolk sac, a placenta and an emerging blood circulation. “The embryo is the best organ-making ...
