Three exciting Harvard and Hubrecht studies find we naturally make stem cells from old cells

We are like salamanders, which regrow lost limbs, after all. Three exciting papers from Harvard and the Hubrecht Insitute find ordinary mammal cells can “go stem cell” when injury occurs. Older cells dedifferentiate to a younger, more potent state to replace lost cells. This could have major ramifications for regenerative medicine. http://www.biosciencetechnology.com/blogs/2014/04/stress-may-naturally-make-stem-cells-mature-cells
