Beta cells (Î²-cells). Beta cells are a type of cell in the pancreas located in the so-called islets of Langerhans. They make up 65-80% of the cells in the islets. The Islets diameter is about 50 to 300 micrometers. They are composed of several types of cells. At least 70 percent are beta cells, which are localized in the core of the islet.
The endocrine portion of the pancreas, or islets of Langerhans, is composed of several cells that secrete hormones directly into the bloodstream. Insulin is a hormone secreted by pancreatic beta cells in response to a rise in blood sugar. The pancreas is located in the abdomen and is a gland organ. 2  It is an important part of the digestive system, producing enzymes and hormones that help break down foods.
