Stem Cells Spur New Eggs in Ovaries of Adult Mice

MouseResearchers in China have demonstrated that female ovaries may be capable of producing new eggs in adulthood and subsequently producing offspring.

That runs counter to the long-held belief that female mammals, including humans, are born with a finite number of the eggs or oocytes needed to produce offspring.

"These stem cells are continuous. They were still around through life and actually transformed to make oocytes. Then they were transplanted into infertile females and produced offspring," said Paul Sanberg, a stem cell researcher and distinguished professor of neurosurgery and director of the University of South Florida Center for Aging and Brain Repair in Tampa. "The study is fascinating," said Sanberg, who was not involved in the research.
