Immunofluorescence staining of endothelial proteins. (A) Expression of VE-cadherin (yellow), ZO-1 (green) and F-actin (red) at the vascular layer of the liver-on-chip model. Representative results of six independent experiments are shown. Scale bars 20 μm (VE-cadherin), 30 μm (ZO-1), 50 μm (F-actin). (B) Computational analyses of MFI of at least 20 ROI per tested condition of the respective protein using random field analysis. Results of six independent experiments are shown. VE-cadherin/ZO-1/F-Actin: Control (16302, [15550–16643]/18705, [17519–21225]/45716, [44318–48369]), CAAP48 (10562, [9561–11287]/16884, [16771–17111]/35908, [32545–39327]), CAAP47 (16458, [15837–16471]/18108, [17377–19042]/39179, [35624–47113]), Scrambled peptide (16017, [15789–16706]/17194, [17085–18375]/40668, [39056–46013]).
