[Ultrastructural study of the early stages of skeletal muscle regeneration in sexually mature animals].
It has been found that during the crush of musculus gastrocnemius in adult rats, there occur two sources of myoblast formation: satellite cells and nucleo-sarcoplasmatic areas that split off injured muscle fibers. The latter process is preceded by changes in the ultrastructure of the perinuclear cytoplasmic zone where microtubules, ribosomes and polyribosomes, fissural cavities, vesicles, myofilaments, and cisterns of the rough endoplasmic reticulum are formed.
