How to join Canada’s stem cell registry, and why Black donors matter
A cheek swab today could be someone’s cure. One Cellular sign-up has already become a match.

For many people with sickle cell disease, a stem cell transplant is the established cure. Finding a donor depends on tissue type, which is inherited, so patients are most likely to match donors who share their ancestry. Black patients are underrepresented on registries, which makes every new Black donor count.
Who can join
Canadian Blood Services’ Stem Cell Registry looks for healthy donors aged 17 to 35, the age range transplant doctors prefer. In Quebec, the registry is run by Héma-Québec. You do not need to know anyone who needs a transplant to join.
How it works
- Register online, or at an event like Cellular
- Swab your cheek. It takes about a minute
- Stay on the registry and keep your contact details current
- If you match a patient, you will be contacted, and you decide what happens next
Most donations today are collected from the blood, in a process similar to giving plasma. Some are collected from the bone marrow, under anesthetic. The registry team explains every step before you agree to anything.
The Cellular model works
Cellular is our travelling stem cell drive and networking night. At Cellular Calgary in March 2025, 28 people joined the registry in one evening, and we learned that someone who signed up at a Cellular event had been matched with a patient who needed a transplant. In 2026, Cellular came to Vancouver.
When a community is united in support of individuals with sickle cell disease, we take one step closer to the eradication of the shame and stigma associated with the disease.
Not 17 to 35? You can still help
Give blood. Many people with sickle cell need regular transfusions, and closely matched blood lowers the risk of complications. Read why Black blood donors matter, then donate with our Partners for Life team at Canadian Blood Services. Our donation page has the details.
Questions people ask
No. Joining is a cheek swab. If you are ever asked to donate, the team will explain both collection methods and support you through the process.
Joining is a commitment to be contacted, not a contract. You can update your status or leave the registry, but tell the registry early so a patient is not left waiting.
Canadian Blood Services recruits new stem cell donors aged 17 to 35. You can still help by giving blood or by encouraging younger people in your circle to join.

Why Black blood donors matter to people living with sickle cell
Many warriors rely on regular transfusions, and the closest matches often come from donors of similar ancestry. Yet just under 1 per cent of Canada’s whole blood donors identify as Black.
