Aging remodels the human muscle secretome, impairing stem cell via sphingolipid metabolism

Aging reduces skeletal muscle regenerative capacity, but how the aged environment impairs muscle stem cells (MuSCs) remains unclear. Skeletal muscle acts as a secretory organ, yet age-related changes in its secretome and impact on stem cells are poorly understood. We performed proteomic and lipidomic analyses of condit...
