Ovarian Stem Cells Produce Eggs in Method That May Aid Fertility
Stem cells taken from human ovaries can produce normal, healthy eggs, scientists demonstrated for the first time in an experiment that may lead to new methods to help infertile women. The finding challenges a belief that women have a fixed number of eggs, or oocytes, from birth that are depleted by the time of menopause, and that their ovaries can't make make more. The research, led by Jonathan Tilly, director of Harvard University-affiliated Massachusetts General Hospital’s Vincent Center for Reproductive Biology, is published today in the journal Nature Medicine.
