part_of part of myotube cell development myotube cell development involved in skeletal muscle regeneration biological_process The process aimed at the progression of a myotube cell over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell. This occurs as part of the process of skeletal muscle regeneration. Myotubes are multinucleated cells that are formed when proliferating myoblasts exit the cell cycle, differentiate and fuse.
