Characterization of Vasoactive Intestinal Peptide Receptors in the Pancreatic AR 4‐2J Cell Line

The AR 4-2J cell line derives from azaserine-induced hyperplastic nodules of the rat exocrine pancreas. Treatment of this cell line by dexamethasone induces in vitro a more highly differentiated phenotype and increases the number of pancreozymin (CCK) receptors with little change in receptor aflinity.’ In this study, we characterized the vasoactive intestinal peptide (VIP) receptors of this cell line. AR 4-2J cells (kindly provided by Dr. Vaysse, INSERM, U 15 1, Toulouse, France) were grown in Dulbecco’s modified Eagle’s medium enriched with 10% fetal bovine serum. Cells were harvested by very mild trypsinization.
