Jon Van Rood: pioneer at the crossroad of human leukocyte antigens and transplantation.

Jon Van Rood (born in 1926) has made major contributions to the fields of transfusion medicine as well as organ and stem cell transplantation. His group was the first to start unraveling the complexity of the human leukocyte antigen (HLA) system through collaborative studies that used panels of sera and leukocyte samples. Furthermore, using HLA typing, he introduced the first HLA-matched platelet transfusions and developed routine leukocyte depletion as a means to prevent HLA alloimmunization. Van Rood has also been active in the fields of kidney transplantation (Eurotransplant) and stem cell transplantation (Europdonor). He combined scientific laboratory research with application to clinical medicine. He retired from his university position in 1991 but remains active in the field.
