Normal cells turned to stem cells without using risky viruses Normally, researchers rely on potentially harmful viruses to deliver the reprogramming factors that change normal cells into induced pluripotent stem cells (iPS). But now Austin Smith and his research team at the Center for Stem Cell Research in Cambridge have discovered a way of reprogramming cells into iPS cells using a single reprogramming factor called Klf4 ... more
