Hemopoietic reconstitution of supralethally irradiated adult dogs of the Cooperstown colony with their own stored bone marrow can produce long-term unresponsiveness to DLA-identical kidney allografts with no need for any additional immunosuppression. Eleven of 18 kidneys transplanted 12 h after replacement of autologous marrow into irradiated recipients currently survive with normal function for as long as 1417 d; 8 of 13 organs transplanted 28 h after marrow replacement, and 8 of 13 organs transplanted 36 h after marrow injection, currently survive up to 502 d, with no further treatment. Alterations in the timing and sequence of each procedure decrease the incidence of unresponsiveness. Survival and function of the kidney allografts were not affected by the rejection of successive skin grafts from the kidney donor. Skin grafts from other DLA-identical donors and DLA-incompatible skin grafts were rejected by the same recipients in uniform fashion.
