ABSTRACT
Immunoreactive insulinwas demonstrated immunohistochemically with antibodies to human and porcine insulin by the avidin-biotin-peroxidase complex method in open-type gastrointestinal cells from sections of the antral stomach and of the upper, midle and lower intestine of the turtles Chrysemys dorbigni and Phrynops hilarii.In both species the concentration of cells positive for insulin-like material was higher in the gastric antrummthan in the gut.The localization of insulin-like material in gastrointestinal mucosal cells of turtles is an unusual finding among vertebrates, because the insulin-containing cells migrate from the mucosal epithelium of the intestine early in vertebrate evolution to the acinar pancreas.The chemical nature of the gastrointestinal insulin-like material and its physiological role remainm to be determined
