Stem cells repair muscle damage in mice
Muscles grow back twice as big, retain their strength
Injured mice injected with stem cells saw their muscles grow back twice as big in just days, with the mice staying big and strong the rest of their lives, U.S. researchers are reporting. This might lead to new treatments for diseases in humans that cause muscle to deteriorate, and maybe even to halt the erosion of muscle strength that comes with age. In the experiment, the team looked at young mice with leg injuries and injected them with muscle stem cells from young donor mice. The cells repaired the injury, and caused treated muscle to increase in size by 170 per cent.
