Summary:
Stem cells might be thought of as trunks in the tree of life. All multi-cellular organisms have them, and they can turn into a dazzling variety other cells—kidney, brain, heart or skin, for example. One class, pluripotent stem cells, has the capacity to turn into virtually any cell type in the body, making them a focal point in the development of cell therapies, the conquering of age-old diseases or even regrowing defective body parts.
Now, a research team at the University of Georgia has shown for the first time that a gene called Myc (pronounced "mick") may be far more important in the development and persistence of stem cells than was known before. Myc is traditionally thought of as a cancer-causing gene, or oncogene, but recent studies from the UGA team have established critical roles for it in stem cell biology. The discovery has important implications for the basic understanding of developmental processes and how stem cells can be used for therapeutic purposes. The research was published today in the journal Cell Stem Cell..
