What Is the Difference Between Allogeneic and Autologous?

Autologous: Auto means self. The stem cells in autologous transplants come from the same person who will get the transplant, so the patient is their own donor. Allogeneic: Allo means other. The stem cells in allogeneic transplants are from a person other than the patient, either a matched related or unrelated donor.

Is autologous or allogeneic better?

Autologous transplants have a lower risk of life-threatening complications; there is no risk of GVHD and no need for immunosuppressive therapy to prevent GVHD and graft rejection. Immune reconstitution is more rapid than after an allogeneic transplant and there is a lower risk of opportunistic infections.

What are the major differences between allogeneic and autologous modes of gene therapy?

The primary difference between allogeneic and autologous are the source of the cells for the therapy. Allogeneic therapies are manufactured in large batches from unrelated donor tissues (such as bone marrow) whereas autologous therapies are manufactured as a single lot from the patient being treated.
