Influence of vWF surface density on LβIXV cell rolling. Mean velocity (A) and the total number (B) of rolling cells were determined on surfaces prepared using solutions with vWF concentrations ranging from 30% to 750% of normal plasma concentration. Values are the mean ± SEM, n = 4 to 8. *Statistically significant from 30% surface, P < .05.
