Experimental details: FIGURE 5 Evaluation of intestinal epithelial glycocalyx and microvilli. (A) Confocal immunefluorescence views of the sugar chain portion (FITC-WGA, green) of the glycocalyx layer secreted by the Caco2 cells cultured in the static Transwell system, or in the peristaltic microfluidic chip in the absence (Peris) or presence (Peris + EC) of endothelial cell for 5 days (bar, 50 mum). Computerized quantification of the coverage (B) and height (C) of the sugar chain portion marked by FITC-labeled WGA measured under the conditions described in (A) ( n = 3; * P < 0.05, ** p < 0.01, *** P < 0.001, **** P < 0.0001). (D) Confocal immunofluorescence views of the villin (red) of the microvilli secreted by the Caco2 cells cultured in the static Transwell system, or in the peristaltic microfluidic chip in the absence (Peris) or presence (Peris + EC) of endothelial cell for 5 days (bar, 50 mum). Quantification of the coverage (E) and height (F) of villin done under the conditions as described in (D) ( n = 3; ** p < 0.01, **** P < 0.0001).

(B) The confocal fluorescence views showing the distribution of the tight junction protein - occludin (green) in the epithelial monolayers cultured in the peristaltic human gut-vessel microsystem under control conditions (EC) versus presence of E. coli with (EC + E. coli ) or without ( E. coli ) endothelial cells for 24 h (bar, 50 mum). (C) Quantification of Papp measured by quantitating fluorescent dextran transport across intestinal epithelial layer under the conditions as described in (B) ( n = 3; * P < 0.05, ** p < 0.01, *** P < 0.001). (D) Confocal immunofluorescence views of the sugar chain portion (FITC-WGA, green) of the glycocalyx layer secreted by the Caco2 cells cultured under the conditions described in (B) (nuclei in blue, E. coli in red) (bar, 50 mum). (E) Confocal immunofluorescence views of the villin of the microvilli secreted by the Caco2 cells cultured under the conditions described in (B) (nuclei in blue, villin in red) (bar, 50 mum). Computerized quantification of the coverage (F) and height (G) of the sugar chain portion and villin measured under the conditions described in (B) ( n = 3; ** p < 0.01, *** P < 0.001, **** P < 0.0001).
