in this report we demonstrate that when the murine macrophage tumor cell line p- 388d1 is incubated for 48-72 h with either concanavalin a-stimulated rat spleen cell supernatant or cloned murine immune interferon ( ifn-gamma ) , the cultured cells release a cell-free factor activity that in turn induces the cell surface expression of ia antigen on the murine monocyte cell line wehi-3 .
