Scientists make old muscles young again in attempt to combat ageing

Researchers at King’s College London, Harvard University and Massachusetts General Hospital have identified for the first time a key factor responsible for declining muscle repair during ageing, and discovered how to halt the process in mice with a common drug.
Although an early study, the finding provides clues as to how muscles lose mass with age, which can result in weakness that affects mobility and may cause falls.
Published today in the journal Nature, and funded by the Biotechnology, and Biological Sciences Research Council, Harvard Stem Cell Institute and National Institutes of Health (US), the study looked at stem cells found inside muscle - which are responsible for repairing injury - to find out why the ability of muscles to regenerate declines with age.
