The World Marrow Donor Association marks World Marrow Donor Day in 2026 on 22 September, to thank volunteer haematopoietic stem-cell donors and to encourage new registry sign-ups. The “Journey of Hope” campaign page gives 19 September a different role: a day focused on professional caregivers — nurses, transplant physicians and the wider clinical team — within the 15–23 September programme. This article follows that calendar rather than assigning a single incorrect date to the whole campaign.

For patients with certain blood cancers and other serious diseases, a stem-cell transplant can be an essential treatment option. Matching is not a matter of blood type alone. Doctors look at inherited tissue characteristics (HLA), and a suitable donor can be hard to find, especially for people from communities underrepresented in registries. Donor diversity and international data exchange therefore have practical importance, not only symbolic value.

Joining a registry does not mean automatic donation. If a match is found, the actual procedure — collection from peripheral blood or, in some cases, from bone marrow — is medically determined, with informed consent. Interested people should use their country’s official registry, which provides information on eligibility, age, health and next steps. The campaign challenges myths without treating the decision as a casual gesture.

WMDA, based in Leiden in the Netherlands, coordinates cooperation among national registries. The 2026 “Hope Hero” message asks people to register, share stories or give financially to help develop transplant programmes where infrastructure is still fragile. In Romania, registration runs through the national stem-cell donor registry, not through unofficial social-media forms.
