  • Title: The cellular origin of the zona pellucida antigen in the human and hamster.
    Author: Bousquet D, Léveillé MC, Roberts KD, Chapdelaine A, Bleau G.
    Journal: J Exp Zool; 1981 Feb; 215(2):215-8. PubMed ID: 6792320.
    Abstract:
    The origin of the zona pellucida in follicles at different stages of maturation was studied in the hamster and human by indirect immunofluorescence microscopy using a specific anti-hamster zona pellucida serum. The earliest detection of the zona pellucida material occurred in the ooplasm of oocytes in primordial follicles. In primary follicles, the fluorescence was localized at the periphery of the oocyte. In secondary and in mature follicles a deposition of fluorescent material was visualized on the inner and outer regions of the zona pellucida. Follicular cells, other than the oocyte, failed to exhibit a fluorescent reaction with the antizona pellucida serum. It is concluded that the oocyte is an important source of the antigenic material of the zona pellucida of hamster and human ova.
