| graft rejection |
Rarely, when a patient has an allogeneic stem cell transplant, the donor stem cells will fail to sustain blood cells production because the recipient's lymphocytes attack the donor stem cells. The conditioning of patients with cytotoxic therapy before transplantation is intended to suppress the recipient immune system sufficiently to avoid rejection of the graft. In occasional recipients, a graft may not be successful because too few donor cells are infused.
