  • Title: Ultrastructural characteristics of capillaries entering and leaving the stria vascularis.
    Author: Watanabe K.
    Journal: Ann Otol Rhinol Laryngol; 1986; 95(3 Pt 1):309-12. PubMed ID: 3717857.
    Abstract:
    Capillaries entering and leaving the stria vascularis were surrounded by layers of basal cells and fibrocytes. The entering capillaries were surrounded by one or two thin basal cells, while the leaving capillaries were surrounded by four or five thicker and interdigitated basal cell layers. Moreover, the layers surrounding the leaving capillaries persisted further into the spiral ligament. Two kinds of filaments were observed in the basal cells, one thin and the other thick. Capillaries were observed to leak horseradish peroxidase before they entered and after they left the stria vascularis. Although the reaction product of horseradish peroxidase was observed in all perivascular spaces of leaving capillaries, very little or no reaction product was observed around some entering capillaries. It is speculated that the layers of basal cells and fibrocytes around entering and leaving capillaries control the vascularis, although the layers around leaving capillaries may be more contractile than those around entering capillaries.
