Senescent cells accumulate with age and contribute to the functional decline of many tissues; however, their role in skeletal muscle is not well understood. Here the authors comprehensively assess cellular senescence in skeletal muscle of young and old mice and detail senescence features in subpopulations of p16+ fibroadipogenic progenitors and p21+ myofibers.
