From: Characteristics of the nasal mucosa of commercial pigs during normal development
The expression of ZO-1 in the nasal epithelium of pigs at different ages. A Immunohistochemical staining of the tight junction protein ZO-1 in the nasal epithelium. CSII represented the anterior part of the respiratory region, CSIII represented the rear part of the respiratory region, and CSIV represented the olfactory region. Scale bars: 100 μm B Bar chart summarizing the statistical analysis of ZO-1 staining results in each group, counted in five random fields (×40) from four cross-sections. All data shown are the mean ± SD from three independent experiments. Statistical significance was obtained using one-way ANOVA. NS no significance, *P < 0.05, **P < 0.01.
