Study unravels new mechanism for muscle repair after physiological damage

Muscle is known to regenerate through a complex process that involves several steps and relies on stem cells. Now, a new study led by researchers at Pompeu Fabra University (UPF, Spain)/Centro Nacional de Investigationes Cardiovasculares (CNIC, Spain)/CIBERNED (Spain) and Instituto de Medicina Molecular João Lobo Antunes (iMM, Portugal), published on 15 October in the journal Science, describes a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fiber nuclei, and independently of muscle stem cells.
