Satellite cells are mitotically potentially active population , adjacent to the striated muscle fibers . The descendants of activated satellite cells ? myoblasts after a number of divisions undergo mergers of muscle fibers , contributing to their growth or regeneration . Skeletal muscle regeneration can also be assisted in extreme cases, no muscle cells , taking myogenesis , such as bone marrow cells . On the other hand , due to its relatively primitive nature of satellite cells reserve used by the body in the process of hematopoiesis .
