Enteroendocrine cells

From Wikipedia, the free encyclopedia

Enteroendocrine cells are specialized endocrine cells of the gastrointestinal tract. They produce hormones such as serotonin[1], somatostatin 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.[2]. Enteroendocrine cells are also found in the duodenum.[3]

Enterochromaffin-like cell and enterochromaffin cells are also considered enteroendocrine cells.[4]
