Delta cell
From Wikipedia, the free encyclopedia
Delta cells (δ-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".
