In vitro development of bone-marrow-derived macrophages. Influence of mouse genotype on response to colony-stimulating factors and autocrine interferon induction.
Responsiveness to granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage CSF (M-CSF) of bone marrow cells derived from different mouse strains was investigated. There were great variations in proliferation between different strains of inbred mice. Bone marrow cells from mouse strains with a high rate of proliferation in response to GM-CSF also had a high proliferating capacity to M-CSF. The response to either CSF did not correlate with a certain H-2 haplotype. GM-CSF induced consistently higher proliferation than M-CSF. Proliferation in response to M-CSF, but not to GM-CSF, could be enhanced by the addition of antibodies against interferon (IFN). IFN is the only known inducer of (2'-5') oligoadenylate (oligo (A] synthetase. This enzyme was induced in macrophages grown in the presence of M-CSF, but not in GM-CSF promoted cells. Enzyme induction was completely abrogated by simultaneous treatment with anti-IFN alpha/beta. Infection of macrophages with herpes simplex virus type 1 (HSV) and vesicular stomatitis virus (VSV) revealed that GM-CSF-promoted cells were highly susceptible to lytic infection by these viruses. In contrast, virus titres in M-CSF-cultured cells were 100-fold lower. We conclude that, contrary to M-CSF, GM-CSF does not induce autocrine IFN during haematopoiesis. As judged from data with BALB/c mice, the sensitivity to the anti-proliferative effect of the autocrine IFN may be a factor which influences M-CSF-promoted proliferation.
