Muscle Rejuvenating Factor Uncovered in Circulating Extracellular Vesicles

Scientists at the University of Pittsburgh have identified that circulating extracellular vesicles carrying transcripts of a longevity enhancing protein called Klotho to muscle progenitor cells, are pivotal in maintaining youthfulness in muscle cells. This work offers insights into why muscles display an impaired ability to heal after injury as we get older and may pave the way toward the development of novel extracellular vesicles-based therapeutics to improve skeletal muscle healing in geriatric populations.
