Muscle regeneration primarily occurs through the activation and differentiation of satellite cells, which are muscle stem cells located between the basal lamina and the sarcolemma of muscle fibers. These cells proliferate and differentiate into myoblasts, which then fuse to repair or form new muscle fibers.
