Dependence of cell migration behavior, morphology, and arrowhead shapes with varying arm lengths. Directional migration trajectories of MC3T3-E1 cells on (a) PDMS gratings with 10 nm height and 5 μm width; and on 10 nm thick patterned TiOx in grating shape with widths of (b) 5, (c) 30, and (d) 50 μm, and arrowhead shape with arm lengths of (e) 10, (f) 20, (g) 35, and (h) 60 μm are shown. Morphology of MC3T3-E1 cells with different shapes on (i) PDMS gratings with 10 nm height and 5 μm width; and on patterned TiOx in grating shape with widths of (j) 5, (k) 30, and (l) 50 μm, and arrowhead shape with arm lengths of (m) 10, (n) 20, (o) 35, and (p) 60 μm are also presented. The scale bar represents 10 μm
