Terminal Platelet Production is Regulated by Von Willebrand Factor
It is established that proplatelets are formed from mature megakaryocytes (MK) as intermediates before platelet production. Recently, the presence of proplatelets was described in blood incubated in static conditions. We have previously demonstrated that platelet and proplatelet formation is upregulated by MK exposure to high shear rates (1800 s(-1)) on immobilized von Willebrand factor (VWF). ...
متن کاملVascular Endothelial Growth Factor Production is Regulated by Gene Polymorphisms
Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
متن کاملVon Willebrand factor and platelet adhesiveness.
A modification of Salzman's method has been used in an attempt to provide an assay in vitro for the von Willebrand factor. Platelet adhesiveness was increased in von Willebrand's disease by previously coating the beads with normal or haemophilic plasma or cryoprecipitate, whereas von Willebrand plasma had no corrective effect. Antihaemophilic factor (AHF) concentrates were studied in the same w...
متن کاملRegulation of von Willebrand factor-platelet interactions.
The formation of thrombi is a multistep process involving several components, including von Willebrand factor (VWF). VWF is an adhesive multimeric protein, which acts as a molecular bridge between the subendothelial matrix and the glycoprotein Ib/IX/V receptor complex. Furthermore, VWF promotes the expansion of the platelet plug by cross-linking platelets via binding to integrin alphaIIbbeta3. ...
متن کاملFactor VIII/von Willebrand factor in subendothelium mediates platelet adhesion.
The present studies were undertaken to determine whether factor VIII/von Willebrand factor (vWF) present in the vessel wall (in addition to that in plasma) may mediate the attachment of platelets to subendothelium. Subendothelium from everted rabbit aorta was exposed to human citrated blood flowing through an annular perfusion chamber at 40 mL/min (wall shear rate of 2,600 s-1 for five minutes)...
