A couple of weeks ago a paper was published in Nature Communications, describing how scientists at the University of Pittsburgh School of Medicine have shown that adult stem cells from the muscle of young mice can improve the health and extend the life of aged mice. While the story didn't make big news at the time, the news is surfacing again, e.g., in a video report by Dr. Marc Siegel on Fox News. The video includes interviews with two of the scientists who did the study, Dr. Laura Niedernhofer and Dr. Johnny Huard. Dr. Siegel does a good job of discussing the key points of the study, including the point that these were not embryonic stem cells, but rather adult stem cells.
