Shear-dependent tether formation during platelet translocation on von Willebrand factor.

Abstract

The adhesion and aggregation of platelets at sites of vascular injury is dependent on the initial binding of the GP Ib/V/IX receptor complex to immobilized von Willebrand factor (VWF). Under flow conditions, this interaction supports platelet translocation that is characteristically stop-start in nature. High resolution imaging of platelets during surface… (More)
