Abstract

Catecholamine accumulation in chick embryos of stages 16 to 24 was investigated using formaldehyde‐induced fluorescence. Fluorescence first appeared at stage 21 in the anterior sympathetic chain. After L‐DOPA treatment, this fluorescence appeared at stage 18. Noradrenaline could not advance the onset of fluorescence or reconstitute fluorescence after its depletion by reserpine at stages 22 to 24. Under no conditions could fluorescence be identified in neural crest cells prior to their aggregation to form the primary sympathetic chain. Noradrenaline induced fluorescence in the neural tube, notochord, myotome, sclerotome, gut mesenchyme and suprarenal cortical cells. In addition to these structures, the dorsal pancreas and some blood cells were fluorescent after 1‐DOPA treatment.

The implication of the results for the neural crest origin of APUD (Amine Precursor Uptake Decaboxylase) cells is considered.

Background: In vertebrate embryos, migration of trunk neural crest cells (NCC) proceeds mainly in two streams: a dorsoventral path between the neural tube and somites, and a dorsolateral one between somites and ectoderm. This last pathway is taken by melanocyte precursor cells (MPC) homing the skin,

Migratory cells in the embryo, such as neural crest cells, are generally thought to move via their own exertions and to be guided by passive cues in their environment. However, inert latex beads have been found to mimic neural crest migration in the chick embryo, indicating the existence of an exter

Background: Osteopontin previously has been shown to be expressed in the early notochord and rostral hindbrain during formation of the rat neuraxis. Both of these sites are known to have important organizing capacities associated with the expression of a number of transcription factors and secreted
