Embryonic stem cells turned into eggs

Embryonic stem cells have been turned into egg cells — the first time scientists have duplicated the process of egg formation and ovulation in the test tube.

The finding opens the possibility that human eggs could be made in large numbers in a culture dish, instead of relying on donors. That could advance research on infertility, the understanding of menopause, and help perfect the process of cloning. Embryonic stem cells can also grow into virtually any cell in the body, so they could be used help revive or repair ailing organs.
