Credit: Juan Carlos Izpisúa Belmonte Two papers published this week appear to bring closer the day when embryonic-like stem cells can be used to treat human diseases. One study describes what scientists say is the safest method yet to produce these cells. The other reports success in using the cells to begin correcting a rare genetic disorder known as Fanconi anemia. Induced pluripotent stem (iPS) cells were first reported in 2006 by Shinya Yamanaka, a researcher at Kyoto...
