Topics | Endocrine System | What is the function of islets in the pancreas? Islets are groups of cells located in the pancreas that make hormones that help the body break down and use food. For example, alpha cells make glucagon and beta cells make insulin. They are also called islets of Langerhans.
Back to Top Causes. In the normal pancreas, cells called islet cells produce hormones that regulate a variety of bodily functions, such as blood sugar level and the production of stomach acid. Tumors that arise from islet cells of the pancreas can also produce a variety of hormones, though some do not. Although islet cells produce many different hormones, most tumors release only one hormone that leads to specific symptoms. Pancreatic islet cell tumors can be noncancerous (benign) or cancerous (malignant). Islet cell tumors include: 1  Gastrinomas (Zollinger-Ellison syndrome). 2  Glucagonomas. 3  Insulinomas.
