(a) Cell migration speed in the groove direction (\({\overline{v} }_{y}\)) and perpendicular to the groove direction (\({\overline{v} }_{x}\)). (b) Directional displacement ratio (i.e., y direction moving length (\({{d}}_{{y}}(0,\Delta)\)) divided by the total travel length (\(D(0, \Delta )\)) from start (t (time) = 0) to finish (\({t}=\Delta\)), see graphical definition in inset) as a function of the time interval (\(\Delta\)) for different groove depths. All error bars are mean \(\pm\) standard error of mean (SEM).
