using autoradiography combined with immunofluorescent localization of muscle-specific light meromyosin and the muscle-specific intermediate filament protein desmin , we have found that embryonic chick myogenic cells cultured in the presence of pma ( 50 nm ) initiate the synthesis of both desmin and muscle-specific light meromyosin and , by these criteria , partially differentiate .
