Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle

Monday, March 30, 2009 - 17:14 in Biology & Nature

In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers -including 2007 Nobel Prize winner Mario R. Capecchi -have created a "switch" that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal.
