Adult Stem Cells Carry Their Own Baggage: Epigenetics Guides Stem Cell Fate, Study in FASEB Journal
7/1/2011 7:37:55 AM
Adult stem cells and progenitor cells may not come with a clean genetic slate after all. That's because a new report in the FASEB Journal shows that adult stem or progenitor cells have their own unique "epigenetic signatures," which change once a cell differentiates. This is important because epigenetic changes do not affect the actual make up in a cell's DNA, but rather, how that DNA functions. Epigenetic changes have been shown to play a role in a wide range of diseases, including obesity, and have been shown to be heritable from mother to child.
