SummaryIn this study, we demonstrate that platelets contain a small hut significant amount of platelet-von Willebrand factor(vWf) not associated with α-granules. When platelets free of plasma proteins are exposed to micromolar concentrations ofdigitonin, plasma membrane permeabilization occurs without disruption of platelet granules. Employing this technique, wehave found that upon exposure of a total platelet population to 8 μM digitonin, 5% of total platelet-vWf is released into the supernatant; this occurs without release of (β-TG from α-granules. When platelets of discrete buoyant density profiles are tested, this extragranular platelet-vWf increased with decreasing platelet density. These findings suggest that a redistribution of platelet-vWf from α-granule to non-granule sites occurs coincident with a decrease inplatelet buoyant density.
