Quantification graphs of permeability and block/leakage ratio in the microfluidic device. a Permeability graph comparing two types of endothelial cells, hCMEC/D3 and hMVEC, they were treated with 3 kda FITC-dextran for 15 min. b Block/leakage ratio graph and c fluorescence images of hCMEC/D3 and hMVEC monolayer after treatment of dextran. d Permeability graph of angiopep-2 with 3 kda dextran. Data represent mean S.E.M. **p < 0.01, ***p < 0.001 by Student’s t test
