Scientists Guide Human Skin Cells To Embryonic State

ScienceDaily (2007-11-21) -- Scientists have genetic reprogrammed human skin cells to create cells indistinguishable from embryonic stem cells. The finding is not only a critical scientific accomplishment, but potentially remakes the tumultuous political and ethical landscape of stem cell biology as human embryos may no longer be needed to obtain the blank slate stem cells capable of becoming any of the 220 types of cells in the human body. Perfected, the new technique would bring stem cells within easy reach of many more scientists as they could be easily made in labs of moderate sophistication, and without the ethical and legal constraints that now hamper their use by scientists.
