  • Title: Monoclonal antibodies as probes to the differentiated exocrine pancreas react to monoclonal islet tumor tissue.
    Author: Beck TC, Madsen OD.
    Journal: Exp Clin Endocrinol; 1989 May; 93(2-3):255-60. PubMed ID: 2550269.
    Abstract:
    Pancreatic exocrine and ductal reacting monoclonal antibodies were derived from a mouse immunized with fixed pluripotent rat islet tumor cells (MSL) and boosted in vitro with fixed and concentrated tumor cell culture supernatant. Antibodies were obtained against duct cells, intercalated ducts, acinar cells and zymogen granules as well as against parietal cells. Unexpectedly, no monoclonal antibodies were directed against the endocrine pancreas, whereas six out of seven exocrine reacting antibodies stained total or subpopulations of cells in sections of monoclonal hypoglycemic MSL-tumors. These data may support the hypothesis of a common endodermal origin of the exocrine and endocrine pancreas.
