Types of Stem Cell Transplants

There are two main types of stem cell transplants: autologous stem cell transplants and allogeneic stem cell transplants. In an autologous transplant, stem cells are collected from the patient’s blood and then given back after treatment. In an allogeneic transplant, the stem cells come from another person. This can be someone within your family or an unrelated donor from the National Marrow Donor Program.

Successful autologous and allogeneic transplants give people new, healthy bone marrow. Allogeneic transplants also give patients a new immune system. Because it comes from a donor’s stem cells, this new immune system may help protect against the underlying cancer.
