Human embryonic stem cells have the potential to develop into eggs and sperm in the laboratory

...ges. For some men and women this would be the only route for producing sperm and eggs. It would not be reproductive cloning as fertilisation would involve only one set of gametes produced in this way and therefore a unique embryo would form. "In addition, if we could produce eggs from HESCs they could als...

Researchers devise new technique for creating human stem cells
