Bone marrow transplantation after lethal chemotherapy in "nude" mice.

Isogenic bone marrow transplantation was performed in "nude" and normal C3H mice after lethal doses of dimethylmyleran (DMM), meso-DMM, and (+/-) DMM were given. Nude mice were not more sensitive to DMM or its isomers than normal mice. With adequate cell doses in the range of 3 X 10(6) to 30 X 10(6) bone marrow cells or 10 X 10(6) to 30 X 10(6) spleen cels, the survival rate after lethal chemotherapy was not significantly different between nude mice reconstituted with a graft from nude donors and normal mice reconstituted with a graft from normal donors. Only with suboptimal cell dose (1 X 10(6) bone marrow cells) was survival superior in normal mice. Thinsic factor. Nude mice accepted also bone marrow grafts from allogeneic nude donors.
