[Behavior characteristics of nerve and muscle cells in mixed cultures of chick embryo skeletal muscle and spinal cord].

A study of features of behaviour of nerve and muscle cells of the chick embryo spinal cord and skeletal muscles, with their simultaneous cultivation, has shown the growth of nerve fibers from explants of the spinal cord towards the muscle tissue. It was also found that muscle fibers were growing intensively to be represented as symplasts. On the basis of these data, a conclusion can be drawn that despite the complete differentiation of the nerve-muscle synapse of the 13 day old chick embryos, the cultured nerve cells maintain the capacity of the oriented growth and formation of the efferent junctions between the explants of the spinal cord and somatic muscles.
