- Enteroendocrine cells
Enteroendocrine cells are specialized
endocrinecells of the gastrointestinal tract. They produce hormones such as serotonin[UIUCHistologySubject|321] , somatostatin, motilin, cholecystokinin, gastric inhibitory peptide, neurotensin, vasoactive intestinal peptide, and enteroglucagon.
Most enteroendocrine cells are found in the
islets of Langerhans, but they are also found in other locations. For example, the G cells (which secrete gastrin) are located primarily in the stomach. [Medcyclopaedia|iv_1/g/G_cell] Enteroendocrine cells are also found in the duodenum. [BUHistology|11604loa - "Endocrine System: duodenum, enteroendocrine cells"] Enterochromaffin-like celland enterochromaffin cellsare also considered enteroendocrine cells.

Rare and slow growing
carcinoidtumors develop from these cells. When a tumor arises it has the capacity to secrete large volumes of hormones.
