Insulin, glucagon, pancreatic polypeptide hormone and somatostatin in the goat pancreas: demonstration by immunocytochemistry

Insulin, glucagon, pancreatic polypeptide hormone (PP) and somatostatin immunoreactive cells were demonstrated in the islet of the goat pancreas by the immunofluorescence procedure. Islet cells showing immunostaining for the hormones appeared to have a characteristic distribution. The demonstration of PP and somatostatin within the pancreas of the goat suggests they may be significant in modulating intra- and extra-islet function in this ruminant species.
