A protein that suppresses stem cells In both humans and mice, the protein Cdc42 increases with aging.
Senescent Cells Harm Muscle Regeneration in Mice
January 4, 2023
New research published in Nature has shown that senescent cells hamper muscle regeneration through inflammation and fibrosis [1]. Cellular senescence is one of the hallmarks of aging.
