'Milestone' stem cell advance reported

Avoids ethical, political, practical obstacles of cloning embryos to make stem cells
Expert: "Tremendous scientific milestone"; likened to Wright Brothers' first plane
Technique creates cancer risk; scientists say it can be avoided in the future
NEW YORK (AP) -- Scientists have made ordinary human skin cells take on the chameleon-like powers of embryonic stem cells, a startling breakthrough that might someday deliver the medical payoffs of embryo cloning without the controversy......
The new work is being published online by two journals, Cell and Science. The Cell paper is from a team led by Dr. Shinya Yamanaka of Kyoto University; the Science paper is from a team led by Junying Yu, working in the lab of in stem-cell pioneer James Thomson of the University of Wisconsin-Madison.
Both reported creating cells that behaved like stem cells in a series of lab tests.
Thomson, 48, made headlines in 1998 when he announced that his team had isolated human embryonic stem cells.
Yamanaka gained scientific notice in 2006 by reporting that direct reprogramming in mice had produced cells resembling embryonic stem cells, although with significant differences. In June, his group and two others announced they'd created mouse cells that were virtually indistinguishable from stem cells..........
"People didn't know it would be this easy," Thomson said. "Thousands of labs in the United States can do this, basically tomorrow."
