Fig. 3From: Contributions of the microbiome to intestinal inflammation in a gut-on-a-chipMorphology of the Caco-2 epithelial cells cultured in a static culture condition and in the gut-on-a-chip with microfluidic flow for 5 days. A and D are phase contrast views of Caco-2 cells monolayer. B and E show the distribution of the cytoskeleton protein, F-actin, in the Caco-2 cells monolayers. C and F show the distribution of the tight junction protein, ZO-1, in the Caco-2 cells monolayers. Scale bars are 25 μmBack to article page
