obsolete myoblast maturation involved in muscle regeneration (obsolete GO:0014914)
OBSOLETE. A developmental process, independent of morphogenetic (shape) change, that is required for a myoblast cell to attain its fully functional state involved in 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.
