The endocrine pancreas of lacertids: an immunocytochemical study of the genera Pedioplanis and Meroles.
The endocrine pancreas from 2 genera of lacertid lizards (Pedioplanis and Meroles) was investigated immunocytochemically for the presence of immunoreactivity to mammalian antisera to insulin (I), glucagon (G), pancreatic polypeptide (PP), peptide tyrosine tyrosine (PYY), neuropeptide tyrosine (NPY), somatostatin 14 (SRIF 14) and somatostatin 28 (SRIF 28), pancreastatin (Pst), galanin (Gl), oxytocin (OT). Cells immunoreactive (IR) to all the antisera used, and nerve fibers IR only to anti-galanin were found. Moreover, three types of colocalized immunoreactivities were detected: type 1 (PP/PYY/NPY), type 2 (G/PP/PYY/NPY), and type 3 (G/PYY/NPY/Pst).
