Physically relevant parameter values for simulation of keratocyte movement in two-dimensions.

parameter	value	physical interpretation
r0	1	initial radius of cell sets a length scale of
	1	coefficient of protrusive forcing term implies a timescale of approximately 45 s
D12	0.5	implies the diffusivity of actin filaments of
D2	50	implies the diffusivity of actin filaments of
k2	0.6–1.8	implies an actin filament growth rate of
	2	assuming a surface tension of 1pN, sets the kinetic scale
	2	implies a bending rigidity of approximately
