Key molecule for stem cell pluripotency discovered (May 27, 2011) -- Researchers have discovered what enables embryonic stem cells to differentiate into diverse cell types and thus to be pluripotent. This pluripotency depends on a molecule -- E-cadherin -- hitherto primarily known for its role in mediating cell-cell adhesion. If E-cadherin is absent, the stem cells lose their pluripotency. The molecule also plays a crucial role in the reprogramming of body cells into pluripotent stem cells. ... > full story
