| pubmed-article:6304332 | pubmed:abstractText | The lining of the vaginal mucosa in primates is a keratinized stratified squamous epithelium. As in other structurally similar epithelia, one function of the vaginal epithelium is to provide a barrier between the external environment and the underlying tissues. The vaginal lining is aglandular and the source of true vaginal fluid has been suggested to be the intercellular channels of the epithelium. On the other hand, other structurally similar epithelia have been shown to have a barrier to the movement of water-soluble molecules through these channels. In the present study, we have examined the permeability of rhesus monkey vaginal epithelium to lanthanum and horseradish peroxidase. Both tracer molecules penetrated the intercellular channels in the lower layers of the epithelium, but were excluded from the channels at and above the granular layer. Neither tracer penetrated significantly between cells at the free surface of the epithelium and usually did not penetrate between cells in the upper layers to any degree from the cut edges of the biopsy. These results are consistent with tracer studies in other structurally similar epithelia and strongly suggest that the upper layers of vaginal epithelium present a barrier to the movement of water-soluble molecules through the intercellular channel system. Freeze-fracture analysis of the epithelium revealed gap junctions and desmosomes between cells in the lower layers, but the former disappear in the upper layers. Unlike other keratinizing epithelia that have been described, random intramembranous particles do not disappear from the plasma membranes of the fully differentiated cells. Fracture planes through the upper layers reveal particle-free lamellae in the intercellular spaces, supporting the idea that intercellular lipids may be one of the components that limits the permeability of the intercellular spaces in this epithelium. | lld:pubmed |
