Abstract
Clones of mouse myeloid leukemic cells that differ in their competence to be induced for normal cell differentiation by the protein inducer MGI produce type C virus. These viruses have been studied for their effect on the viability, multiplication, and differentiation of normal bone marrow cells either with or without the addition of MGI. Virus from leukemic clones that can differentiate normally to mature macrophages and granulocytes (MGI+D+ clones) induced some multiplication of myeloblasts in the bone marrow, but the cells did not differentiate without adding MGI. In the presence of MGI, this virus then induced an increased number of colonies whose cells differentiated to mature macrophages or granulocytes as in colonies of uninfected cells. Virus infection also resulted in a decrease in the amount of MGI and fetal calf serum that was required for colony formation. Virus from MGI+D+ clones, in the presence of MGI, was 500-fold more effective in increasing colony formation than virus from the differentiation-defective MGI-D- clones, although both types of virus replicated with equal efficiency in the normal bone marrow cells. No such increase was obtained after infection with the Friend leukemic virus complex or the Moloney murine leukemia virus. Infection with virus from a MGI+D+ clone that was differentiated by MGI mainly to macrophages induced a higher percentage of macrophage colonies than virus from MGI+D+ clones that were differentiated by MGI to granulocytes and macrophages. Studies with isolated myeloblast colony-forming cells from the bone marrow have indicated that these are the target cells for the virus. Infections of these isolated myeloblasts with virus from MGI+D+ clones induced some multiplication without differentiation in the absence of MGI, and increased the viability and multiplication of the myeloblasts without inhibiting their ability to differentiate in the presence of MGI. The results, therefore, indicate that virus from MGI+D+ cells can increase the viability and multiplication of normal myeloblasts in the bone marrow without blocking the ability of these cells to be induced to differentiate by MGI, and that this effect was directly related to the competence of the leukemic host cells to be induced for normal differentiation. It is suggested that the difference between the effect of virus from MGI+D+ and MGI-D- cells may be due to a difference in their integration sites in relation to the genes that control cell viability, multiplication, and differentiation.
