the results suggest that vwf is altered during rapid passage of blood through the glass-bead column so that it attaches to gp ib , exposing gp iib/iiia , which then binds the altered vwf or fibrinogen , either of which can induce platelet aggregation ( platelet-platelet adhesion ) and thus retention in the column .
