From the Washington Post: scientists have discovered the master gene in stem cells that gives them the ability to form all other types of human cells. This means we are closer to being able to create stem cells from any human cell, which means we are closer to the grail of true regenerative medicine. If we can understand the mechanisms that make stem cells work, therapies for many diseases and conditions of aging will soon follow. All in all, even though it is early, basic research, this is very good news. More on stem cell basics can be found at InfoAging.org.
