Babies born from skin cells may sound like science fiction, but scientists have come a step closer to making it a reality.
Researchers in the US have turned human skin cells into eggs capable of being fertilised by sperm, a breakthrough that could one day allow infertile women, or two gay men, to have children to whom they are genetically related.
The approach could allow babies to be born without biological mothers, with DNA from two fathers.
Building on a technique used in the 1990s to clone Dolly the sheep, scientists first removed the genetic material, the nucleus, from a skin cell.
