Stem-Cell Breakthroughs May Ease Ethical Quandaries

Researchers have created embryonic stem cells without using eggs or destroying embryos, a move that may overcome key ethical quandaries of stem-cell research.

In experiments on mice, four independent teams of scientists pulled off a feat that is the biological equivalent of turning back time: They returned old, mature cells to their primordial, embryonic state. Further experiments showed that the derived cells had the same properties as true embryonic stem cells, such as the ability to turn into muscle, heart, nerve and other tissue types.
