Establishment and characterization of a transplantable erythroblastic leukemia in C3H mice.
A disease with the characteristics of an erythroblastic leukemia was induced by X-ray irradiation of 300 Rads in C3H mice. The leukemia is transplantable in syngeneic mice by i.v. injection of the spleen cells. The mice show almost pure erythroid cells of various differentiation stages in peripheral blood. The number of total nucleated cells in the peripheral blood increased, but hematocrit and platelet number decreased. Reverse transcriptase activities were measured in spleen and liver of the mice and the data suggested that the leukemia was not induced by retrovirus infection. This leukemia is distinguishable, in this respect, from diseases reported by Friend or Rauscher. The leukemia will offer a good animal model for the studies on non-viral leukemogenesis and disorders of erythropoiesis.
