Abstract

Calorie restriction is known to promote healthy aging, which includes prevention of muscle loss. We investigated the effect of rodent calorie restriction on mitochondrial respiration and clonogenic capacity of muscle satellite stem cells, since metabolic alterations are known to regulate stem cell activity. Surprisingly, short or long-term calorie restriction do not change mitochondrial or glycolytic function. Nevertheless, both short- and long-term calorie restriction enhance myogenic colony formation. Overall, our results show that not all changes in satellite stem cell function are accompanied by metabolic remodeling. (AU)
