The endocrine cells of the pancreas; the beta cells within the islets of Langerhans are the source of the critically important hormone insulin.

Groups of cells in the pancreas; the islets contain beta cells, alpha cells, and delta cells.

The Islets of Langerhans are the ribbon- shaped structures within the pancreas which house the insulin-producing beta cells. Isolation The process by which islets are separated from the other cell types within the pancreas. In the Edmonton protocol, special enzymes were used to digest the unusable pancreas tissue. A further stage of purification is also required.

The islets of Langerhans comprise a cluster of highly specialized cells in the pancreas. These cells produce and secrete hormones that help the body break down and use food. Discovered in 1869 by Paul Langerhans, the islets contain four types of cells: alpha cells, which produce glucagon; beta cell, which produce insuline; delta cells, which produce somatostatin; and PP, which produce pancreatic polypeptide.

Known as the insulin-producing tissue, the islets of Langerhans do more than that. They are groups of specialized cells in the pancreas that make and secrete hormones. Named after the German pathologist Paul Langerhans (1847-1888), who discovered them in 1869, these cells sit in groups that Langerhans likened to little islands in the pancreas. There are five types of cells in an islet: alpha cells that make glucagon, which raises the level of glucose (sugar) in the blood; beta cells that make insulin; delta cells that make somatostatin which inhibits the release of numerous other hormones in the body; and PP cells and D1 cells, about which little is known. Degeneration of the insulin-producing beta cells is the main cause of type I (insulin-dependent) diabetes mellitus.

The endocrine (i.e., hormone-producing) cells of the pancreas are grouped in the islets of Langerhans. Discovered in 1869 by the German pathological anatomist Paul Langerhans, the islets of Langerhans constitute approximately 1 to 2% of the mass of the pancreas. There are about one million islets in a healthy adult human pancreas, which are interspersed evenly throughout the organ, and their combined weight is 1 to 1.5 grams.
