Stem-cell finding alters ethical controversy

When University of Wisconsin-Madison researchers succeeded in reprogramming skin cells to behave like embryonic stem cells, they also began to redefine the political and ethical dynamics of the stem-cell debate, a leading bioethicist says. R. Alta Charo, a UW-Madison professor of law and bioethics, says the scientific finding could have far-reaching effects on the social dimensions of the ongoing controversy over embryonic stem cell research.
