Delta cell

From Wikipedia, the free encyclopedia

Delta cells (δ-cells or D cells) are somatostatin producing cells.

They can be found in the stomach, intestine and the Islets of Langerhans in the pancreas.

In rodents delta-cells are located in the periphery of the islets; in humans the islet architecture is generally less organized and delta-cells are frequently observed inside the islets as well.

In the electron microscope, delta-cells can be identified as cells with smaller and slightly more compact granules than beta cells.

[edit] Clinical significance

A tumor of the delta cells is called a "somatostatinoma".
