Multilineage hematopoietic disorders induced by transplantation of bone marrow cells expressing the v-fms oncogene

J M Heard et al. Cell. 1987.

Abstract

Mouse bone marrow cells infected with a helper-free retrovirus containing v-fms were engrafted into lethally irradiated mice. Dominant provirus-positive clones emerged in the spleens of some recipients within 1 month. When spleen cells were transplanted into lethally irradiated secondary recipients, clonal erythroleukemias or B cell lymphomas expressing the v-fms-coded glycoprotein developed. Other secondary recipients repopulated by "unmarked" progenitor cells or by cryptic provirus-positive precursors present in the spleens of the same donor mice did not develop disease; thus cells expressing v-fms did not invariably have a proliferative advantage after transplantation. Several primary engrafted recipients developed myeloproliferative disorders that were provirus-positive without evidence of clonality. Although expression of the c-fms product (CSF-1 receptor) is normally restricted to cells of the mononuclear phagocyte series, the v-fms-coded glycoprotein can contribute to proliferative abnormalities of multiple hematopoietic lineages.
