[Changes in myosatellitocytes in response to injuries of the muscles of the esophagus].

Processes occurring in the striated muscle tissue in the rat oesophagus have been studied light- and electron-microscopically under various lesions of the oesophageal muscles. Stages of the regenerative process are described. The muscle tissue in the oesophagus is revealed to possess the ability of myosatellitogenesis. Ultrastructural peculiarities of various types of myosatellitocytes are reported. Segregation of nucleo-sarcoplasmic segments from some injured muscle fibers is demonstrated. Owing to these data, it is possible to consider the striated muscle tissue in the oesophagus as one of the varieties of the somatic muscle tissue.
