title: Presence and distribution of neuroendocrine cells in the gastroenteropancreatic endocrine system of fallow deer foetuses.
abstract: The gastroenteropancreatic endocrine system was studied in 11- and 17-week-old fallow deer foetuses using an immunocytochemical technique. In the gastrointestinal tract, gastrin-, serotonin-, somatostatin- and cholecystokinin-containing cells were found: their frequency and distribution were also determined. Anti-glucagon and anti-insulin antibodies did not stain any cells along the gut. In the pancreas, somatostatin-, pancreatic polypeptide-, insulin- and glucagon-immunoreactive cells were detected. The different distribution and number of neuroendocrine cells, in the two investigated stages of foetal life, are discussed. Data obtained in this study were compared with those published in a previous study on the gastrointestinal system of the adult fallow deer.
