  • Title: The endocrine pancreas of Triturus cristatus: an immunocytochemical study.
    Author: Putti R, Varano L, Laforgia V, Cavagnuolo A.
    Journal: Basic Appl Histochem; 1990; 34(3):219-28. PubMed ID: 1980057.
    Abstract:
    The endocrine pancreas of Triturus cristatus carnifex was studied with the aid of immunocytochemical methods, showing cells immunoreactive to anti-insulin serum (B cells), a small population of cells immunoreactive to anti-glucagon serum only (A cells), rare cells positive to anti-PP serum only (PP or F cells), and a larger population of cells immunoreactive both to anti-glucagon and to anti-PP sera. B cells lied in the core of the islet, while the A/PP cells were located at the periphery, forming digitations extending into the exocrine parenchyma. D cells were present in small number in the islet while they were more numerous scattered in the exocrine parenchyma. A/PP cells as well as D cells showed one or two long cytoplasmic extensions often in contact with blood vessels.
