The Interaction of the Platelet and von Willebrand Factor

A culture of pig aortic endothelial cells was used for experiments to investigate the interaction between the platelet and von Willebrand factor. An antibody was raised in rabbits to purified porcine von Willebrand factor. A semi-confluent culture of pig endothelial cells was stained immunofluorescently by the sandwich technique using anti-Willebrand factor IgG. An extensive extracellular meshwork of microfilaments was revealed. In endothelial cell cultures from von Willebrand pigs, no immunoreactive microfilaments were found. Immunoelectronmicro-scopy with peroxidase linked antibody has been used to identify similar filaments in normal pig endothelial cells. Washed platelets were shown to adhere to semiconfluent or damaged normal endothelial cell cultures. If the cultures had been previously incubated with anti-Willebrand factor IgG, the washed platelets did not adhere. There was no adherence of platelets when they were added to semiconfluent or damaged von Willebrand endothelial cells.
