Delta cell
From Wikipedia, the free encyclopedia
(Redirected from Delta cells)
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.
A tumor of the delta cells is called a "somatostatinoma".
