ABOUT WMDD
WMDD is celebrated all over the world every 3rd Saturday of September to thank and celebrate voluntary stem cell donors, that have signed up selflessly to be a donor for any patient in need of a life-saving stem cell transplant.
In 2025 it falls on September 20th. The event will be celebrated in more than 60 countries on all continents reaching hundreds of thousands of people through social as well as conventional media coverage.
WHO IS BEHIND WORLD MARROW DONOR DAY?
World Marrow Donor Day (WMDD) is an initiative of the World Marrow Donor Association, the largest organisation dedicated to donor care and providing information for the facilitation of a search process. Our members are organising events all over the world to thank all blood stem cell donors worldwide. It is also a day to raise awareness among the general public and decision-makers about the importance of registering as a stem cell donor and the impact of blood stem cell transplantation on a patients’ life.
WE BELIEVE…
…that all patients deserve a chance to receive a stem cell transplant. Over 8% of the global searches result in zero matches in our global database of over 41 million donors. Our target is to reduce this number. You can help by sharing your experience as a stem cell donor or recipient or by signing up as a potential lifesaver.

JOIN THIS DAY
WMDD primarily aims to reach and engage with the general public, but also seeks to raise awareness among policymakers, public authorities, industry representatives, researchers, health professionals and anyone who has a genuine interest in blood stem cell donation and blood stem cell transplantation.
This website includes information about WMDD and international donor/recipient stories.
All forms of participation for WMDD, big or small, are encouraged. Be creative and let your heart speak.
WMDD would not be possible without the continuous efforts of individuals and organisations around the world, building awareness locally in order to secure a potential donor for every patient in need of a stem cell transplant.
