The authors determine whether the development of satellite cells and their transformation into myoblasts under the influence of regenerating muscle tissue occurs in irradiated muscle. In the control series seven days after surgery, degenerative changes occurred over a considerable extent in the muscle fibers of the proximal stump: a loosening, fragmentation, and disappearance of myofibrils, the vesiculation of the sarcoplasmic reticulum, and mitochondrial swelling and breakdown. The stimulation of the processes of postradiational repair occurs under the influence of transplanted regenerating muscle tissue into irradiated traumatized muscle. This results in the restoration of its capacity for regeneration by both myosymplastic and myoblastic means.
