Title: Enteroendocrine cells in small intestine (human, rat)
Description: Stain: (A) Hematoxylin-eosin, jejunum, human. (B) Duodenum, human. Anti-serotonin-antibody immunoperoxidase staining with DAB and hematoxylin counterstaining (Kindly provided by late Dr. A. Verhofstad). (C) Electron microscopy scheme of an enteroendocrine cell of the argyrophilic type II, human. (D) Electron micrograph of an enteroendocrine cell in the jejunum, rat.
In all four figures it is clearly depicted that these endocrine cell types all deposit their secretory granules below the nucleus near the basal lamina and in the vicinity of capillaries. In the electron micrographs (C, D) the granules are small and very electron dense. As these cells can be stained with chromium silver salts they are called also enterochromaffin cells. At least 20 different cell types have been identified with different hormone productions such as serotonin, somatostatin, cholecystokinin, gastrin, neurotensin, vasoactive intestinal peptide, gamma-endorphin etc.
Keywords/Mesh: enteroendocrine cells, small intestine, jejunum, duodenum, enterochromaffin cells, serotonin, electron microscopy, histology, POJA collection
