Could women grow brand new eggs?

摘要

Stem cells placed in the ovaries of sterilised adult mice have apparently given rise to fresh eggs and healthy offspring, reigniting the debate over whether women are born with all the eggs they will ever have. rnIf the finding can be replicated in women, it would revolutionise reproduction, opening the door for later child-bearing and providing a source of eggs for infertile women. But despite early signs that similar egg-producing cells may exist in women, there are doubts over whether the mouse and human cells are what they seem.
