iPS cells yield live mice

The Scientist | Researchers have created live mice from induced pluripotent stem (iPS) cell lines, demonstrating iPS cells are as pluripotent as embryonic stem (ES) cells, according to two studies published online today.

"This ability to make a mouse from the cells of a Petri dish is the most stringent standard that mouse embryonic cells are held to, and iPS cells now meet that standard, which has been a lingering doubt," said stem cell biologist George Daley of the Harvard Stem Cell Institute and Children's Hospital Boston, who was not involved in the work. "It assures us that iPS cells can do all the things that ES cells can do."
