The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. Discovered in 1869 by German pathological anatomist Paul Langerhans, the pancreatic islets constitute approximately 1-2% of the pancreas's mass and receive 10-15% of its blood flow.here are about one million islets distributed throughout the pancreas of a healthy adult human, :914 each of which measures about 0.2 mm in diameter.
1 Tumors that form in islet cells are called islet cell tumors, pancreatic endocrine tumors, or pancreatic neuroendocrine tumors (pancreatic NETs). 2  Exocrine pancreas cells make enzymes that are released into the small intestine to help the body digest food. They cluster together in many small groups (islets) throughout the pancreas. 2  Endocrine pancreas cells are also called islet cells or islets of Langerhans. 3  Tumors that form in islet cells are called islet cell tumors, pancreatic endocrine tumors, or pancreatic neuroendocrine tumors (pancreatic NETs).
