Figure 3From: 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 virusPercentage of cells (a-b) and collagen (a-c) in nasal and nasopharyngeal mucosae (Van Gieson-staining). By giving different colors to collagen and nuclei (setting a threshold), relative amounts of collagen and nuclei were measured during cultivation (72 h) by means of light microscopy. No significant differences in the percentage of cells and collagen were found at any time point. Data represent means ± S.D. of triplicate independent experiments.Back to article page
