Microdevices do not affect passive permeability of Caco-2 cells. A) Caco-2 cells were grown on transwells for 21 days prior to measurement of apical to basal flux of 4 kDa FITC Dextran transport. The values shown are means ±SD of 3 biological replications. There was no effect of the microdevices on FITC dextran flux indicating no effect on tight junctions. B) Caco-2 cells were grown on 96 well plates for 14 days prior to measurement of intracellular calcein concentrations at 4°C. The values shown are means ±SD of 3 biological replications. There was no effect of the microdevices on calcein accumulation at 4°C.
