[Formation of myoblasts after injuries to skeletal muscle tissue].
The musculus masseter and the tongue in 75 mature rats have been injured by means of a scalpel, carbonate laser ray and ethanol administration. The regeneration process has been studied light and electron microscopically. Myosatellites that are constantly revealed in the skeletal muscle tissue, are the main source of myoblast formation under all the types of the muscle injury. When laser ray and ethanol are applied, myoblasts are also formed by means of segregation of the nucleo-sarcoplasmic territories of the muscle fiber.
