"A large number of our patients who do search for matches do have a good chance of finding a stem cell match," said Dr. Heidi Elmoazzen, director of the stem cell program at Canadian Blood Services. Men also tend to make the best stem cell donors because they can give more cells, she said. People can also donate peripheral blood stem cells through a process that's very similar to donating blood. About 50 per cent of people who've signed up for the stem cell registry back out when they get called, she said.
