Help people with blood cancers or disorders get a life-saving transplant
Every minute counts
Every 3-4 minutes, someone in the U.S. is diagnosed with a blood cancer. Many of those people may need a blood stem cell transplant (sometimes called a bone marrow transplant). A transplant can cure or treat 75-plus diseases, including blood cancers such as leukemia and other blood disorders, like sickle cell.
With 75% unable to find a suitable donor in their family, the NMDP RegistrySM is their vital link to the world's most diverse pool of potential matches, including people like you.
At NMDPSM, we do more than match patients with donors. We also support them through transplant—physically, emotionally and financially—and conduct research to improve patient outcomes.
Patients like Max need you
Fifteen-year-old Max is a dedicated student and pianist who has big dreams. He also has a serious blood disorder and needs a blood stem cell transplant to survive. But for Hispanic patients like Max, finding a donor can be harder due to underrepresentation on the registry. Help change that by signing up to be a potential donor.

Finding a match against the odds
“I realize I can never repay [my donor, Tiana] for what she’s done,” said transplant recipient Donna (above right), “but I can sure say thank you. I can say you are awesome a lot. I can say you are fabulous a lot.”
Be the reason someone lives
Noah was called as a match three times and donated twice. “Getting the call, being in this chair right now and actually donating, it’s just a really beautiful thing and I’m so grateful to be a part of it.”
Your cells could be the G.O.A.T.
After her leukemia diagnosis, Nicole underwent three blood stem cell transplants, including one from an unrelated donor. ”My donor is forever a part of me. She's basically like our fourth sibling now.”
