Virgin Births Lead to Transplantable Stem Cells

From Scientific American:

Egg Stem cells created from unfertilized mice eggs are successfully transplanted without immune rejection. In the future individual egg cells may serve as the source for stem cells that doctors can transplant back into people if necessary to treat nerve damage and debilitating diseases, if researchers can extend a new procedure used on mice for making transplantable stem cells.

“This is just a small step along the way, but it’s an important one,” says stem cell researcher Paul Lerou of Children’s Hospital Boston and Boston’s Brigham and Women’s Hospital. Lerou and his colleagues extracted stem cells from embryolike clusters of cells grown from the unfertilized eggs of female mice that the researchers coaxed into dividing. They injected the stem cells back into related mice, where they grew without being rejected by immune cells.
