RACK1 Is Evolutionary Conserved in Satellite Stem Cell Activation and Adult Skeletal Muscle Regeneration

Researchers demonstrated for the first time that Receptor for Activated C-Kinase 1 (RACK1) was an important evolutionary conserved factor in adult satellite cell (SC) differentiation both in vivo and in vitro. Indeed, RACK1 participated in skeletal muscle homeostasis by activating SC and is required for proper myogenesis of damaged skeletal muscle.
