Lung  Transplantion Correct Von Willebrand Deficiency

I was close to some of the early work on attempts to identify the site of factor VIII synthesis (1-3).  Transplanted organs included the liver, spleen, and kidney.  Equivocal results were obtained which can now be understood with the identification of the endothelial cell as site of synthesis (4-6).  However, the identification of the lung as a site of synthesis for von Willebrand factor, a traveling companion for factor VIII came a surprise.   Ferés (1) and coworkers in Spain announce that lung transplantation corrected a mild case of von Willebrand Disease.
