Effect of cortical tension on neutrophil rolling velocity. (a) Variation of the rolling velocity with shear stress for different values of the cortical tension. Lines that terminate in a sphere indicate transition to the cell spreading regime (r > 0.9R). (b) Modulation of the contact radius with shear stress for different values of the cortical tension. Termination of the line for Tc = 500 pN/μm corresponds to transition to the tethering regime. Ligand density NL = 50 μm−2.
