Observations of satellite cells in rat skeletal muscle incubated in vitro.
Satellite cells were studied in the peripheral fibres from isolated rat muscles, which had been incubated for various periods of time. The cells were in an activated state with prominent organelles and increased cytoplasm visible. Mitosis of some satellite cells was occasionally observed. It is suggested that when incubated muscle preparations are used as models for physiological systems in vivo, the state of the satellite cell population should be taken into consideration.
