Scientists discover protein which helps babies stick to the womb

                Scientists have discovered a protein which helps embryos stick to womb and improve treatments for recurrent miscarriages. The study by scientists at the University of Sheffield shows that a protein called Syncytin-1, which was the result of a viral infection of our primate ancestors 25 million years ago, is first secreted on the surface of a developing embryo even before it implants in the womb. This means the protein is likely to play a major role in helping embryos stick to the womb as well as the formation of placenta.
