Indocyanine green (ICG) intake capacity in sodium taurocholate cotransporting polypeptide (NTCP)-expressing and organic-anion-transporting polypeptide 1B3 (OATP1B3)-expressing HT-29 cells. (a) The cells were measured by using flow cytometry at the APC-Cy7 wavelength (785 nm) to observe ICG intensity. (b) The diluted series cells were detected using an in vivo imaging system (IVIS). (c) One hour after ICG was added to the control and the NTCP- and OATP1B3-expressing HT-29 cells, the cells were monitored under a confocal microscope. C: control HT-29. U: untreated. N: NTCP-expressing HT-29 cells. O: OATP1B3-expressing HT-29 cells.
