Fig. 5From: Contributions of the microbiome to intestinal inflammation in a gut-on-a-chipImpedance analysis in a human gut-on-a-chip. Impedance spectra showing the development of an intestinal epithelial barrier cultured with A Caco-2 cell only and B co-culture with Caco-2 cells and HUVECs. C Epithelial resistance with respect to culture days, showing that the resistance of the co-culture model was increased with culture days. D Epithelial impedance versus calculated TEER analysis in the co-cultured modelBack to article page
