Stem cells have been coaxed into creating everything from liver cells to beating heart tissue. Recently, these versatile cells were even used to make fertile mouse sperm, suggesting that stem cell technology might eventually be able to play a role in the treatment of human infertility.
Now two types of stem cells have been turned into viable mouse egg cells that were fertilized and eventually yielded healthy baby mice. Details of this achievement were published online October 4 in Science.
Katsuhiko Hayashi, of Kyoto University’s School of Medicine, were able to create the eggs with embryonic stem cells as well as with induced pluripotent stem cells (formed from adult cells).
