From: Contributions of the microbiome to intestinal inflammation in a gut-on-a-chip
Morphology of the Caco-2 epithelial cells co-cultured with HUVECs in a static and flow culture condition for 5 days. A Morphological analysis of intestinal specific proteins under a static and flow condition. Scale bars are 50 μm. B Morphological analysis of polarized columnar epithelium. Fluorescence confocal micrographs (vertical cross-sectional views at 5 days after onset) show a vertical cross-section of the epithelium highlighting cell shape and polarity. Horizontal scale bars are 50 μm and vertical scale bars are 25 μm. C The average height of Caco-2 cells grown in the gut-on-a-chip without and with fluidic flow (***p < 0.001)
