Metabolic control of muscle stem cells
Muscle stem cells, or satellite cells, are a population of adult stem cells involved in muscle growth and indispensable for adult skeletal muscle regeneration. As the quiescent state is perturbed, satellite cells undergo profound metabolic changes, named metabolic reprogramming, driving cellular activation, commitment and differentiation. Thus, modulation of cellular metabolism, by altered nutrient availability or with aging, can impact satellite cell stemness and fate, as well as differentiation ability.
