In a study published in Nature Medicine, researchers report finding egg-producing stem cells in human ovaries. They also report being able to make some of those ovarian stem cells grow into immature eggs that may someday be useful for reproduction.
At this point, such “seed” eggs can’t be fertilized by sperm. But if scientists are able to entice them to mature and can prove they can be fertilized and grow into embryos -- a feat that has been reported in mice -- it would overturn a long-held scientific belief that women can’t make new eggs as they get older.
“What it does is really open a door into human reproduction that 10 years ago didn’t even exist,” says researcher Jonathan L. Tilly, PhD, director of the Vincent Center for Reproductive Biology at Massachusetts General Hospital, in Boston....."
