Stem cells can become anything, but not without this protein

Stem cells can become anything, but not without this protein: In a finding that could be important to the use of all kinds of stem cells in treating disease, scientists have discovered the crucial role of a protein called Mof in preserving the 'stem-ness' of stem cells, and priming them to become specialized cells in mice. It plays a key role in the "epigenetics" of stem cells -- that is, helping stem cells read and use their DNA.
