The ontogeny and distribution of nerve cell bodies and fibres which contain vasoactive intestinal polypeptide-, substance P-, enkephalin- and neurotensin-like immunoreactivity have been studied in the chicken gastrointestinal tract, using immunocytochemistry. All four peptides were found in nerve fibres, with characteristic distribution patterns, which, in the cases of vasoactive intestinal polypeptide, substance P and methionine enkephalin were similar to those described for the mammalian gut. In addition, many of these fibres were shown to arise from intrinsic neurons, since immunoreactive nerve cell bodies for each of the peptides studied were observed. Neurotensin-immunoreactive nerves were confined to the upper part of the tract and neurotensin immunoreactive cell bodies were only observed in embryonic and newly hatched chicken gut. All four peptides were first observed at 11 days of incubation, or Hamburger-Hamilton stage 37, 20 in the upper part of the tract, particularly in the gizzard. Substance P and methionine enkephalin were subsequently seen in more caudal regions, while vasoactive intestinal polypeptide developed from each end of the tract. Adult patterns of immunoreactivity in nerve fibres were achieved during the first week after hatching. A striking observation was that immunoreactive neuronal cell bodies were much more abundant in the gut of young chickens and chicken embryos than in that of adult birds.
