Ultralarge von Willebrand factor (vWF) strings are secreted by, and anchored to, stimulated human endothelial cells. A disintegrin and metalloprotease with thrombospondin domains-type 13 cleaves the ultralarge vWF strings into large soluble vWF multimers. Normal plasma contains a nonproteolytic reducing activity that subsequently rapidly diminishes the size of the large soluble vWF multimers.
