Satellite cells, or myosatellite cells - are mononuclear progenitor cells found in skeletal muscle tissue. As progenitor cells those cells are able to divide, or transform into syncytium skeletal mucsle cells. This mechanism helps to repair damaged segmental fibre and to grow syncytium cells during long muscle work.
The satellite cells have almost no cytoplasm, very few organelles and a small nucleus. The cells have pleanty nuclear heterochromatin and a high nuclear-to-cytoplamic volume ratio.
The satellite cells are attached to syncytium skeletal muscle cells between sarcolemma and basal lamina.[1]
