Aspects of normal and dystrophic chicken muscle grown in vitro.
Pectoral muscle from normal and dystrophic New Hampshire chicken embryos was dissociated and grown in vitro. Marked differences between the two types of cell cultures were observed with the light and electron microscopes during early myogenic stages. The diseased myoblasts assumed a polarized affect and fused into smaller and fewer myotubes. Pseudostraps rather than true muscle straps were often seen in diseased cultures. There was also a delay in the appearance of myosin containing thick myofilaments in differentiating dystrophic muscle cells.
