A pancreatic polypeptide (PP)-like immunoreactant is present in the glicentin-containing cell of the cat intestine

BPP-like immunoreactivity was identified in the intestinal mucosa of the cat. In light microscopy BPP immunoreactive cells were found identical to glicentin-containing cells or L-cells. By immunoelectronmicroscopy, BPP-like material was localized within the glicentin-containing secretory granules.
