GENERAL HISTOLOGY

Detailed explanation-1: -Islets of Langerhans are islands of endocrine cells scattered throughout the pancreas. A number of new studies have pointed to the potential for conversion of non- islet cells in to insulin-producing -cells to replenish -cell mass as a means to treat diabetes.

Detailed explanation-2: -The islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. 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 distributed throughout the organ.

Detailed explanation-3: -The endocrine portion consists of the pancreatic islets, which secrete glucagons and insulin. Alpha cells in the pancreatic islets secrete the hormone glucagons in response to a low concentration of glucose in the blood.

Detailed explanation-4: -The islets of Langerhans are a cluster of cells within the pancreas that are responsible for the production and release of hormones that regulate glucose levels.
