“I had no reason not to”
At just 24, Alfred Mureithi from Islington, London, has shown how one simple decision can make a life-changing difference. After joining the stem cell donor register, Alfred was matched with a patient sooner than he expected and went on to donate his stem cells earlier this year.
Alfred’s story highlights the importance of becoming a stem cell donor and the urgent need for more people to come forward, particularly from Black, Asian and mixed-heritage communities.
From registration to saving a life
Alfred joined the stem cell donor register last year after donating blood. Initially, he believed stem cell donation involved a procedure on the bone marrow. After learning more about the process, including that stem cells are usually collected from the bloodstream, he decided to register.
Before his donation, Alfred received injections to increase the number of stem cells circulating in his blood. The collection itself took several hours, but he described the experience as easier than he had anticipated.
His journey is a powerful reminder that becoming a potential donor is a straightforward step that could give someone with a blood cancer or other serious blood disorder another chance at life.
Why more donors are needed
For many people living with leukaemia and other blood cancers, a stem cell transplant can offer a potentially life-saving treatment. However, finding a suitable donor is not always easy.
Patients are more likely to find a compatible donor when their genetic and tissue characteristics match. Because these characteristics are often shared among people with similar ancestral backgrounds, having a diverse donor register is essential.
Black, Asian and mixed-heritage communities remain underrepresented on the UK stem cell donor register. This can make finding a suitable match particularly challenging for patients from these backgrounds.
Alfred’s story shows why representation matters – and how one person’s decision to register can make an extraordinary difference.
