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.
The hormones made by the cells in the islets of Langerhans within the pancreas include: 1  Insulin - which helps to regulate sugar levels in the blood. 2  Glucagon - which works with insulin to keep blood sugar levels balanced. 3  Somatostatin - which helps to control the release of other hormones. 4  Gastrin - which aids digestion in the stomach.
