Ultrastructural changes in satellite cells after denervation and reinnervation of skeletal muscles

Changes taking place in the satellite cells after denervation and reinnervation of skeletal muscles are studied. A certain degree of similarity and synchrony of the changes occurring in these cells and in the muscle fibers is established during the degenerative and regenerative processes. Formation of new satellite cells and fusion of the same with muscle cells is not observed. These findings are explained by the fact that postdenervation changes in the skeletal muscles are not so heavy as in their direct lesion when, according to literature data, the satellite cells participate directly in the reparative process.
