| Abstract |
|
The GEP endocrine cells of the African clawed toad, Xenopus laevis, were studied immunohistochemically. Five kinds of the endocrine cells were identified in this study A moderated number of 5-HT-immunoreactive cells were detected throughout the gastro intestinal tract, being almost uniform frequency. Gas/CCK -immunoreactive cells were restricted to the basal portion of the pyloric gland and among the duodenal mucosa. A rare glucagon-immunoreactive cells were weakly reacted in the fundic region of the stomach and observed in the exocrine portions of the pancreas. Somatostatine-immunoreactive cells were distributed throughout the gastrointestinal tract with except for the rectum, and not only the periphery of the islets but also the exocrine portions in the pancreas. No CGs- and insulin-immunoreactive cells were found in the gastrointestinal tract, whereas in the pancreas, the later was seen in the central region of the islets and the exocrine portions. |
