Ultrastructural localization of pancreatic polypeptide in the F cell of the dog pancreas.
The F cell of the dog pancreas has been identified as the specific cell type containing pancreatic polypeptide. This localization of pnacreatic polypeptide was accomplished by immunocytochemical staining of ultrathin sections and direct electron microscopic identification. Verification of the specificity of the reaction was obtained by blocking experiments on serial sections of the same cell. It is proposed that the name F cell be used for defining in all species the islet cell that contains pancreatic polypeptide.
