The hematopoietic disregulation in adult mice induced by the malignant histiocytosis sarcoma virus (MHSV) and the Harvey murine sarcoma virus (Ha-MuSV), which both possess c-Ha-ras-related oncogenic sequences, was investigated. Spleen focus formation induced by MHSV and Ha-MuSV was not restricted by the Fv-2 resistance locus in congenic DDD and C57BL/6 mice, unlike leukemogenesis induced by Friend virus, Rauscher virus, and the myeloproliferative sarcoma virus (MPSV). C57BL/6 mice were much more resistant to MHSV and Ha-MuSV-induced spleen focus formation than DDD mice regardless of their Fv-2 state. Infection of DDD mice with MHSV caused a systemic histiocytic neoplasia, best described as murine malignant histiocytosis. Transformed histiocytic cells proliferated excessively in the bone marrow, spleen, and lymph nodes and, in the final stages of the disease, in all major parenchymal organs. The Ha-MuSV caused a strikingly different benign histiocytic tumor in DDD mice and, unlike MHSV, did not induce a rapid, progressive splenomegaly in C57BL/6 mice. Infection of DDD mice with MHSV induced a rapid and synchronized depletion of early and late erythroid precursor cell pools. In MHSV-infected C57BL/6 mice comparable changes were observed with dissimilar kinetics. Macrophage colony-forming cells of MHSV-infected mice were increased in number and proliferated independently of stimulating growth factors. The disease induced by MHSV in mice can thus serve as a model for malignant histiocytosis in humans.
