Fig. 4. Images of SV40-HCECs on the patterned and planar surfaces prior to and after exposure to uniform fluid shear. Before Shear: (A) 400 nm pitch, (C) 4000 nm pitch (E) planar surface. Insets in A, C and E show typical cell morphology on these surfaces. AfterFlow (maximum wall shear stress of 80 Pa): (B) 400 nm pitch, (D) 4000 nm pitch, (F) planar surface. Scale bar: 100 µm.
