Stem cells are essential for blood cell production and are found in the bone marrow and in umbilical cord blood. During stem cell transplantation, your unhealthy blood cells or stem cells are destroyed using chemotherapy or radiation. They are replaced by healthy stem cells collected from your body or a healthy donor and transfused into your body, like a blood transfusion. Stem transplantation is not a surgical procedure. The infusion takes less than two hours, but the recovery takes several months.
The decision to use stem cells from your body or from a healthy donor depends in part on the disease being treated. If a healthy adult donor is not available, stem cells from umbilical cord blood can be used. Duke was one of the first transplant centers in the world to perform umbilical cord blood transplantation.
- Autologous stem cell transplantation uses your own stem cells.
- Allogeneic stem cell transplantation uses cells from a healthy related or unrelated donor.
- Syngeneic transplantation uses stem cells from an identical twin.
