Previous reports on skeletal muscle myogenesis have shown that postmitotic spindle-shaped myoblasts express muscle-specific proteins, some of which are organized into nascent myofibrils. However, we show that, in skeletal muscle cultures derived from 12-day chick embryos, by 6 h after plating the predominant mononucleated cell type that expresses muscle-specific proteins is a round cell. These round myoblasts appear to precede spindle-shaped myoblasts in development, since the latter are more… CONTINUE READING
