In teleost fishes, unlike many other vertebrates, the spinal cord originates as a solid structure, the neural keel, which subsequently hollows out. Unlike vertebrates in which the neural tube is formed from neural folds, and where the neural crest arises from wedge-shaped masses of tissue connecting the neural tube to the general ectoderm, teleosts do not possess a clear morphological neural crest. Initially, the dorsal surface of the keel is broadly attached to the ectoderm as described by Shepard (1961). As the neural primordia become larger and more discrete, the region of attachment narrows, and cells become loose (the ‘loose crest stage’). These cells represent the neural crest. Subsequently they begin to migrate and to differentiate into the various derivatives of neural crest. Both sensory and sympathetic neurons arise from neural crest. At the time of their migration the cells are not morphologically distinguishable.

Stage 16+ axial isolates from embryos of the zebrafish, Brachydanio rerio (Hamilton-Buchanan), were separated from their yolk spheres and epidermis. Rhombencephalic level explants, with intact bilateral cardiac rudiments, were maintained in nutrient medium for 20 days at 24 ± 2 °C. All embryo cultures became attached to the culture substrate and underwent subsequent differentiation. Ten out of 25 explants showed bilateral migrations of determined but initially undifferentiated cardiac mesoderm. The progressive structural and functional differentiation of zebrafish cardiac monolayers and intact rudiments are described for the first time.
