I. Representative images showing mTFP (cyan) and Venus (yellow) fluorescence in HBVPs which have direct contact with control (upper panel) or MCT1 (lower panel) siRNA-treated BMECs. VECAD immunostaining was used for endothelial staining. J. Quantification of the mTFP/Venus fluorescence ratio of laconic in HBVPs which have direct contact with control (siCON) or MCT1 (siMCT1) siRNA-treated BMECs. (n=8 from independent experiments. Error bars indicate the standard error of the mean (SEM) from unpaired Student's t test.)
