part_of part of myoblast fusion myoblast fusion involved in skeletal muscle regeneration GO:0014905 A process in which non-proliferating myoblasts, after migrating to the site of injury, fuse into existing damaged fibers or fuse to myotubes to form new fibers, as part of the process of skeletal muscle regeneration. A myoblast is a mononucleate cell type that, by fusion with other myoblasts, gives rise to the myotubes that eventually develop into skeletal muscle fibers. biological_process myotube differentiation involved in skeletal muscle regeneration
