  • Title: Immunocytochemical identification of growth hormone cells in the adenohypophysis of the golden hamster.
    Author: Lue CM, Wang SM, Lu KS, Lin HS.
    Journal: Proc Natl Sci Counc Repub China B; 1987 Jul; 11(3):253-9. PubMed ID: 3321114.
    Abstract:
    Somatotrophs or growth hormone (GH) cells in the adenohypophysis of golden hamsters were identified by immunocytochemical staining with polyclonal rabbit anti-human GH. They were oval or columnar in shape, and had secretory granules of two size ranges, 90-150 nm and 280-320 nm, which were present in the same cells; no subtypes of GH cells were observed. Secretory granules were located in the peripheral portion of the cytoplasm or concentrated at the vascular pole of the cell. Flattened cisternae of the rough endoplasmic reticulum in parallel array and a moderately developed Golgi apparatus were often found in the cytoplasm. No sex difference was noticed in the population ratio of GH cells. Immunocytochemical staining with anti-GH or anti-prolactin (PRL) antibodies on separate adjacent sections revealed that the GH and PRL were stored in two different cell types.
