Canada’s stem cell registry isn’t diverse enough to help those who need it

The search for a matching stem cell donor becomes exponentially more difficult if you are a member of an ethnic minority — and especially if you’re mixed race. For the Canadians in need of a stem cell donor, it can be a matter of life and death. Only 31 per cent of the roughly 440,000 donors Canada’s stem cell registry are ethnically diverse, and that figure falls to just three per cent if you look at those who are mixed race. The wait, says those who need donations most, can threaten lives.
