Antibodies against VWF inhibit PMN extravasation in the inflamed cremaster. The cremaster muscle of mice (4 mice per group) was prepared for intravital microscopy. Inflammation was induced by superfusion with keratinocyte-derived chemokine (KC), and the vessels (n ≥ 4 per mouse) were analyzed for rolling (A), adherent (B), and transmigrated (C) leukocytes. Error bars show SEM. ***P ≤ .001.
