  • Title: LH-producing cells in the ovine pituitary. An electron microscopic immunocytochemical study.
    Author: Dacheux F, Dubois MP.
    Journal: Cell Tissue Res; 1978 Apr 28; 188(3):449-63. PubMed ID: 348327.
    Abstract:
    An immunocytochemical technique using the peroxidase-antiperoxidase complex (PAP) was applied to identify and characterize the LH-secreting cells in the ovine pituitary at the ultrastructural level. These cells, round or oval in shape, possessing flattened cisternae of the rough endoplasmic reticulum, contain one class of secretory granules (mean diameter 250 nm) and large dense bodies (600 to 800 nm in diameter). LH molecules and the two subunits LHalpha and LHbeta were localized on the secretory granules and on the small granules near the Golgi complex. The large dense bodies, the cisternae of the endoplasmic reticulum and the saccules of the Golgi complex showed no reaction product.
