The macrophage-specific CSF (CSF-1), purified from murine L cell-conditioned medium, supports the in vitro proliferation and survival of various murine mononuclear phagocyte colony-forming cells. In this report we describe the production and functional characterization of two monoclonal antibodies (mAb) to CSF-1 obtained from rat X rat hybridomas. These two mAb are functionally distinct and recognize different epitopes on CSF-1. The mAb 5A1 binds to and inhibits the biologic function of CSF-1, and the second mAb (D24) binds CSF-1 but does not neutralize its biologic activity. The mAb 5A1 inhibits colony formation of tissue mononuclear phagocyte colony-forming cells as well as the committed bone marrow stem cells for both granulocytes and monocytes. The extent of colony inhibition by mAb 5A1 is dependent on the tissue origin of colony-forming cells. CSF-1 complexed with mAb 5A1 does not bind to its cell surface receptor of peritoneal exudate macrophages, and mAb 5A1 does not complex with cell-bound CSF-1. Although both bone marrow cell-derived macrophages and J774.1 macrophages bind CSF-1, mAb 5A1 inhibits the proliferation of only bone marrow cell-derived macrophages. The non-neutralizing mAb D24 does not block binding of CSF-1 to its cellular receptor, and it recognizes cell-bound CSF-1.
