STEM CELLS CREATE MIGHty mice 

Stem cell injections boosted the leg muscles of mice and warded off the typical loss of muscle mass that comes with aging. The discovery could be useful in treating humans with degenerative diseases such as muscular dystrophy, as well as help everyday people prevent at least some of the ravages of time, the researchers said. Scientists removed stem cells from the legs of three-month-old healthy mice and injected them into the legs of mice that had temporary leg muscle injuries, induced by barium chloride injections. The technique repaired the injuries within days and made the treated muscle double in size.
