Figure 2From: Development and use of a polarized equine upper respiratory tract mucosal explant system to study the early phase of pathogenesis of a European strain of equine arteritis virusEvaluation of the continuity (a) and the thickness (b) of nasal and nasopharyngeal basement membrane (reticulin-staining). The collagen type III reticular fiber layer of the basement membrane (lamina reticularis) (indicated by arrows) remained continuous during the entire experiment (72 h). No significant differences in the thickness of the basement membrane were found at any time point. Data represent means ± S.D. of triplicate independent experiments.Back to article page
