DISCOVERIES REPRODUCTION
In a groundbreaking development, scientists have grown synthetic human embryos for 14 days, without eggs, sperm or a womb.
A research team from the Weizmann Institute of Science in Israel generated the synthetic embryos using pluripotent stem cells, which havedevelop into many different cell types. The resulting embryos, described in a new study published in , mimic the 3D structure and key characteristics of a human embryo.
