Pancreatic polypeptide cells are most active and secrete more pancreatic polypeptide after a meal with high protein, fasting, physical activity, and acute hypoglycemia. These same cells are inhibited by somatostatin, an inhibitory gastrointestinal hormone, and the presence of glucose. [7] Pancreatic Polypeptide From a Mouse Cell
Pancreatic polypeptide regulates pancreatic secretion activities by both endocrine and exocrine tissues. It also affects hepatic glycogen levels and gastrointestinal secretions. Its secretion in humans is increased after a protein meal, fasting , exercise, and acute hypoglycaemia , and is decreased by somatostatin and intravenous glucose .

[3] 50 Pancreatic polypeptide: Peptide: Pancreas: PP cells: pancreatic polypeptide receptor 1: Self-regulation of pancreatic secretions (endocrine and exocrine).
The endocrine cells constitute the beta cells which make insulin, alpha cells which secrete glucagon, delta cells which secrete somatostatin and the PP-cells which secrete pancreatic polypeptide. [3] Pancreatic progenitor cells have been shown to arise from cells originating from the developing foregut during mammalian development.
Delta cells comprise ca 5% of the cells in the islets [1] but may interact with many more islet cells than suggested by their low numbers. In rodents, delta-cells are located in the periphery of the islets; in humans the islet architecture is generally less organized and delta-cells are frequently observed inside the islets as well. [2]
The mesothelium is composed of an extensive monolayer of specialized cells (mesothelial cells) that line the body's serous cavities and internal organs. The main purpose of these cells is to produce a lubricating fluid that is released between layers, [ 4 ] providing a slippery, non-adhesive, and protective surface to facilitate intracoelomic ...
Ductal cells comprise about 10% of the pancreas by number and about 4% in volume. Its function is to secrete bicarbonate and mucins and to form the tubule network that transfers enzymes made by acinar cells to the duodenum. Ductal cells have a proliferation rate of about 0.5% in normal adults, but mitotic activity goes up when the pancreas is ...
This was later confirmed by the findings that in the absence of both Nkx2.2 and Pax4 genes, β-cells fail to form and are replaced by ε-cells. Overall, the findings were that there is a population of ghrelin-producing ε-cells in the mouse pancreas, and that knockout of insulin -producing β-cells leads to an enormous amount of ε-cells.
