Scientists Throw Open the Floodgates with Synthetic Embryo

Researchers in the United Kingdom have created “synthetic” embryos from mouse stem cells. The embryos have formed brains and beating hearts along with the foundations of other bodily organs.
With the initial stages of success for this synthetic embryo, many see this as a possible new avenue for recreating the first stages of life using stem cells instead of eggs or sperm, the University of Cambridge reported.
The researchers published their findings Thursday in the journal Nature.
