Making healthy stem cells from normal adult cells
Scientists may have found a safer way of giving a flake of skin the biologically alchemical powers of embryonic stem cells. They turned adult cells into versatile, embryonic-like cells without causing permanent damage -- potentially solving the central problem of a promising but uncertain field of stem cell science."This is certainly a major stem cell milestone," said Advanced Cell Technologies chief scientific officer Bob Lanza, who was not involved in the research. "It's the first ray of light that iPS cells could soon be used to treat patients." These iPS cells -- short for induced pluripotent stem cell -- debuted less than a year ago: By using viruses to insert key developmental genes, researchers coaxed human skin cells into an embryonic state, capable of growing into almost any other type of tissue.
