There are many different donor options available
If you are seeking an allogeneic transplant, but you cannot find a donor that is suitable, there may be other options. Umbilical cord blood transplants are used in centers around the world and have shown to be very effective. There is also the option of parent-child transplant and haplotype mismatched transplant. This is when the match is around half instead of complete - such as a parent, child, or sibling.
