PP cell
pancreatic polypeptyde

PP cells are found in the tail's periphery.

PP cells have very few organelles and few granules.

PP cells (gamma cells) producing pancreatic polypeptide (3-5%)

F cells (PP cells) are pancreatic polypeptide producing cells in the islets of Langerhans of the pancreas.

Pancreatic polypeptide (PP) is a polypeptide secreted by PP cells in the endocrine pancreas predominantly in the head of the pancreas.

In particular, while rodent islets are characterized by a predominant proportion of insulin-producing beta cells in the core of the cluster and by scarce alpha, delta and PP cells in the periphery, human islets display alpha and beta cells in close relationship with each other throughout the cluster.
