Allogeneic refers to something that is genetically different from an individual or group. In a medical context, it means a transplant or graft that comes from a donor other than the recipient, such as bone marrow or organ transplants.
Graft - versus - host disease (GVHD) is a long - term side effect that occurs in about half of allogeneic stem cell transplant patients. (cityofhope.org)
The only documented long - term complete remissions reported in multiple myeloma patients have occurred with allogeneic bone marrow transplantation, where a donor's blood stem cells (graft) are transplanted into the patient (host) with multiple myeloma. (cancerresearch.org)
Peripheral blood stem cells are generally used in autologous transplantations, while either marrow or peripheral blood stem cells are used in allogeneic transplantations. (cityofhope.org)
