Why is pancreatic islets important?
A Pancreas. Pancreatic islet cells are the main source of insulin and glucagon, which are produced by β cells and α cells, respectively. The secretion of hormones from pancreatic islets is mainly regulated by the glucose concentration.
What diseases affect the pancreas?
