D-cells, or Delta cells, can be found in the stomach, intestine, or Islets of Langerhans (the hormone producing regions of the pancreas which also produce glucagon and insulin). Delta cells produce somatostatin, a regulatory hormone. When somatostatin is released it interacts with specialized receptor cells, these cells control the production of other hormones. Somatostatin coming in contact with a somatostatin receptor will inhibit the production of hormones that receptor controls.
