Histologically, the islets consist of three major and at least two minor cell types.
Beta cells, which synthesize and secrete insulin, make up about 60% of a typical islet.
Alpha cells are the source of glucagon, 30% of islet tissue.
Delta cell, which are less abundant, produce somatostatin.
F cells, which secrete pancreatic polypeptide.
Fifth cell type that secretes ghrelin.
Fifty cell typ
