Influence of neurons on the occurrence of fibre types and myosin light chains in cultured presumptive slow and fast myoblasts.


Myoblasts from 9-day-old quail embryo slow anterior latissimus dorsi (ALD) and fast posterior and latissimus dorsi (PLD) muscles were co-cultured with neurons. The presence of neurons allowed ALD-derived muscle fibres to express characteristic features of a slow muscle (occurrence of alpha' and of beta' fibres and predominance of slow myosin light chains… (More)
