Fig. 3. Addressing selected cells within an epithelial monolayer. MDCK cells stably expressing ML-GFP (green) were grown as polarised monolayer on the biochip. By using a confocal microscope the image plane on which the cells are attached to the chip surface was observed during introduction of medium containing 10 μM BambL-Cy5 (red) through the basolateral channel starting at t = 5 min. A yellow circle indicates the perimeter of the pore.
