Histopathological sections performed with HE dyes. (A) Histopathological score represented by arbitrary units. The sections were blindly evaluated and considered alterations were highlighted. Tissue edema (square brackets), inflammatory infiltrates (black arrow head) and ulcerations (red arrow). Naïve section presenting normal histoarchitecture. Mice colon sections submitted to IHC. (B) Representative sections and percentage (%) of marked area for Claudin-1 marker. Black square represents the apical region. (C) Representative sections and, number of positive cells per field for MUC-2 marker. Black square represents the apical region. (D) Representative sections and, number of positive cells per slide for PCNA marker. Black arrow heads indicating positive cells. (E) Representative sections and number of positive cells per field for CD163 marker. Black arrow heads indicating positive cells. n = 10 mice/group. Scale bar: 50 μm. Sections: 4 μm. *p < 0.05, **p < 0.01, ***p< 0.001, ****p < 0.0001 vs DSS. &p < 0.05, &&&&p < 0.0001 vs DSS + Eudragit-SBA-15.
