FIG. 3.

(a) Contours of shear stress exerted over a cluster of immobilised HEK-293 cells, obtained through numerical stimulations when a flow rate of 120 μl/min is applied through the microchannel. The presented results display the shear stress experienced for a single cell, double and triple cells, patterned parallel and normal to the direction of flow. (b) The values of average shear stress exerted on cells in different configurations. F and B are used to denote the front and back positioned cells, and L, M, and R are used to denote the left, middle, and right positioned cells.
