Two teams reprogram skin cells for pluripotency

Two studies published today report that human somatic cells can be reprogrammed into a pluripotent state that resembles human embryonic stem cells.

Using the same factors in humans, the cells could be subsequently differentiated into human cardiac cells and neural cells. The paper embargo was lifted early today because of an embargo break. In the second paper, appearing in linkurl:Science;http://sciencenow.sciencemag.org/cgi/content/full/2007/1120/1 , James Thomson's group at the University of Wisconsin, Madison, used a lentivirus and the four linkurl:transcription factors;http://www.the-scientist.com/article/display/53404/ OCT4, SOX2, NANOG, and LIN28 to reprogram human skin...
