Collecting stem cells for allogeneic transplant

If you're having a transplant using stem cells from a donor (allogeneic transplant), you will need a donor. Once a donor is found, stem cells are gathered from that person for the transplant.

Stem cells can come from your donor's blood or bone marrow. Your transplant team decides which is better for you based on your situation.

Another type of allogeneic transplant uses stem cells from the blood of umbilical cords (cord blood transplant). Mothers can choose to donate umbilical cords after their babies' births. The blood from these cords is frozen and stored in a cord blood bank until needed for a bone marrow transplant.
