Skin Cell Research Derails Stem Cell DebateTwo groups of scientists report that they've found ways to make stem cells without starting with an unfertilized egg. One group has figured out a way to reprogram skin cells in mice to create new tissue.
The embryonic stem cell debate may be a thing of the past.
At Whitehead Institute in Boston, researchers have succeeded in modifying a skin cell so that it behaves like an embryonic stem cell. And at Harvard University, scientists have shown that it's possible to make clone mice from previously fertilized eggs.
