  • Patent number: 6943021
    Abstract: Disclosed is a cervico-vaginal tissue equivalent comprised of vaginal epithelial cells and immune cells, cultured at the air-liquid interface. The tissue equivalent is capable of being infected with a sexually transmitted pathogen such as a virus (e.g., HIV), a bacteria, a helminthic parasite, or a fungus. The tissue equivalent is also capable of undergoing an allergic-type reaction or an irritant-type reaction. The tissue equivalent is characterized as having nucleated basal layer cells and nucleated suprabasal layer cells, and further as having cell layers external to the suprabasal layer progressively increasing in glycogen content and progressively decreasing in nuclei content. Immune cells of the tissue equivalent are primarily located in the basal and suprabasal layers. Also disclosed are methods for producing the tissue equivalent.
