Aim: The aim of the study was to identify the distribution pattern and frequency of endocrine cell types in the digestive tract of Varanus salvator. Materials and Methods: The presence of endocrine cells (glucagon, somatostatin, and serotonin) in the digestive tract (esophagus, stomach, and intestine) was detected using the avidin-biotin complex (ABC) method. Results: Three types of endocrine cells immunoreactive to antisera glucagon, serotonin, and somatostatin were found in the caudal portion of the small and large intestines but were not observed in the esophagus, stomach, and caput and medial sections of the small intestine. Endocrine cells distributed in the digestive tract of V. salvator vary in color intensity, from weak to sharp, in response to the primer antibody. Conclusion: Endocrine cells in the digestive tract that is immunoreactive to glucagon, somatostatin, and serotonin are those found in the caudal portion of the small and large intestines. They are varied in distribution pattern, frequency, and color intensity.

Gut Endocrine Cells

The aim of this experiment was to find out whether or not, at early stages of development, progenitors of the various types of gut endocrine cells are localized to one or more specific regions of the gastrointestinal tract. Transverse strips of blastoderm two to four somites in length were excised between the levels of somites 5 and 27 in chick embryos at 5- to 24-somite stages and were cultured as chorioallantoic grafts. The distribution of endocrine cells in the grafts revealed confined localization of progenitor cells only in the case of insulinimmunoreactive cells. Theprogenitors of cells with somatostatin-, pancreatic polypeptide-, glucagon-, secretin-, gastrin/CCK-, motilin-, neurotensin- and serotonin-like immunoreactivity were distributed along the length of the presumptive gut at the time of explantation; indeed, in many cases they were more widespread than are their differentiated progeny in normal gut of the same age. This finding indicates that conditions in grafts must differ from those that operate in the intact embryo. Also it may explain the occurrence of ectopic gut or pancreatic endocrine cells in tumours of the digestive tract.
