Israeli researchers create synthetic embryos from stem cells

(JNS) - Scientists at Israel's Weizmann Institute of Science have successfully created complete synthetic models of human embryos using laboratory-grown stem cells, according to an official release from the Institute.

The synthetic embryos were nurtured outside the womb and survived up to 14 days of development with all the features characteristic of their stage, even though no sperm or eggs were used.

The findings, published in the peer-reviewed journal Nature, hold significant promise for diverse fields such as infertility research, drug testing and tissue transplantation, and offer a deeper...
