World Marrow Donor Association (WMDA)

The World Marrow Donor Association (WMDA) connects patients in need of life-saving stem cell transplants with volunteer donors worldwide. WMDA was informally initiated in 1988 by three pioneers in the field of transplantation: John Goldman (United Kingdom), E. Donnall Thomas (United States) and Jon J. van Rood (the Netherlands). Since 1994, WMDA has united experts from over 57 countries to ensure safe, ethical, and efficient donor matching.

WMDA provides a global platform to streamline searches and promote equal access to treatment. As a key player in blood stem cell donation, WMDA collaborates with international partners, including the WBMT (Worldwide Network for Blood and Marrow Transplantation)

Our work is guided by a dedicated members, with daily operations managed from our office in Leiden, the Netherlands.
