There are different types of stem cell / bone marrow transplants.
- Allogeneic Transplant - the stem cells are collected from someone other than the patient. The donor may be a family member or someone that is found to match the patient from a registry of unrelated donors.
- Syngeneic Transplant - the stem cells are collected from the identical twin of the patient and then transplanted to the patient.
- Autologous Transplant - the stem cells are collected from the patient before the high-dose chemotherapy and returned to the same patient after the transplant.
Stem cells may be taken either from the blood stream (peripheral blood stem cells) or from the bone marrow. They may be called by different names, but all of the types of transplant have the same goal, to get rid of bad cancer cells and replace them with good cells.
