Hello, I am the founder of Mixed Marrow and thought you would find our information helpful to answer your question. This thread came up in one of our news alerts so I joined the site so I can answer.
Here is a great TIME article that we were interviewed for on the topic:
Besides bone marrow, we are finding that research shows umbilical cord blood offers hope to hard-to-match patients as well. We are learning more and more about what cord blood can do and it is a painless, risk free procedure many do not know enough about. 95% of umbilical cords are discarded each year!
