Fig. 6. Time-lapse images of cells on the 400 nm pitch, 4000 nm pitch and planar surface as they experience fluid shear stress: (A,F,K) No Flow (static conditions). (B-O) Wall shear stress of 20 Pa (B,G,L), 40 Pa (C,H,M), 60 Pa (D,I,N), 80 Pa (E,J,O). Arrowheads indicate position of detached cells. Scale bar: 50 µm.
