(A) Representative phase contrast image of HIO-derived epithelial cells seeded into the Chip. Cells were exposed to continuous media flow at 30 μL/h and imaged after 0, 3, 5, and 7 days. Static Chip was imaged after 7 days. Scale bar = 200 μm. (B) Stitched phase contrast image of HIO-epithelial cells that were exposed to continual media flow at 30 μL/h for 5 days. Scale bar = 1 mm. (C) Representative brightfield image of cross-section of Chip that was exposed to continual media flow at 30 μL/h for 14 days. Scale bar = 250 μm. Representative fluorescent images showing (D) E-cadherin/CDH1 (red), ZO-1 (green), DAPI (blue), and (E) E-cadherin (blue), CDX2 (red), and Villin (green), in cross-section of Chip under conditions similar to C. Both scale bars = 50 μm. (F) Representative fluorescent images showing E-cadherin/CDH1 (red), and MUC2, lysozyme, FABP2, and chromogranin A (all green), counterstained with DAPI (blue), in cross-section of Chips that were exposed to continual media flow at 30 μL/h for 7 days. Scale bar = 10 μm. (G) Representative images of in situ hybridization for LGR5+ and WDR43+ (white arrows) in conditions similar to F. Scale bar = 10 μm. (H) Representative fluorescent image showing E-cadherin/CDH1 (blue), Ki67 (green), and DAPI (blue) in conditions similar to F. Scale bar = 100 μm. Graph shows percent Ki67+ nuclei per section.
