YOU can give a chance to live!

The Stem Cell Donor Recruitment Week is an annual event, preceding the World Marrow Donor Day. This event is an initiative from GenDx, in cooperation with Matchis, the Dutch center for stem cell donors.

This year, we organized various online activities throughout the week (13-17 September 2021). All activities were focused on sharing knowledge and spreading awareness regarding the importance of becoming a potential stem cell donor, and stem cell donation in general.
To support Matchis financially, GenDx has agreed to cover the registration costs for all new donors who registered during Stem Cell Donor Recruitment week 2021, using our event code at registration. This resulted in a donation of €1.575,-
