What are the benefits of using preserved stem cells from a family member versus non-related sources?

If you’re related to the donor, your chances of survival are much greater. If it's your own baby stem cell or if it's your own stem cells, then you don't have to be on immunosuppressants whatsoever. Also, other family members can be partial matches as well, which can also contribute to general survival rates. It also limits the chances of rejection and being on immunosuppressants. So there's definitely a huge difference.
