von Willebrand factor in plasma, platelets, and selected tissues of ferrets.
By standard laboratory methods the presence and activity of von Willebrand factor (vWF) was detected and characterized in the ferret (Mustela putorius furo); vWF in plasma, platelets, and selected tissues (thoracic aorta, cranial vena cava, thoracic portion of caudal vena cava, and lung) was documented. Activity, antigenic concentration, plasma multimeric distribution, and localization within tissues were similar to those features in other species. Two differences were apparent: multimeric distribution of platelet vWF was skewed toward the smaller molecular weight multimers, and mucous goblet, but not ciliated, cells of the bronchial epithelium stained positive for vWF. Larger molecular weight multimers were not released subsequent to administration of 1-deamino-8-D-arginine-vasopressin. The ferret may be a useful animal model in studying the role of vWF in hemostasis, thrombosis, and atherosclerosis. In particular, the role of small molecular weight multimers found in ferret platelets may provide further insight into the roles of platelet vWF multimeric distribution, platelet adhesion, and thrombosis.
