Stem cells can become anything – but not without this protein

How do stem cells preserve their ability to become any type of cell in the body? And how do they “decide” to give up that magical state and start specializing?

If researchers could answer these questions, our ability to harness stem cells to treat disease could explode. Now, a University of Michigan Medical School team has published a key discovery that could help that goal become reality.

In the current issue of the prestigious journal Cell Stem Cell, researcher Yali Dou, Ph.D., and her team show 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.

Their results show that Mof plays a key role in the “epigenetics” of stem cells — that is, helping stem cells read and use their DNA. One of the key questions in stem cell research is what keeps stem cells in a kind of eternal youth, and then allows them to start “growing up” to be a specific type of tissue.
