The new type of stem cells could be useful for growing personalized replacement tissues, according to a study in Thursday's issue of the journal Nature. But because of their source, their highest promise would apply to only half the world's population: men.
Embryonic stem cells can give rise to virtually any tissue in the body, and scientists think they may offer treatments for diseases like Parkinson's and diabetes and for spinal-cord injuries.
