(a) Time-line for the development inhibition assay utilised for measuring macrophage cytotoxic and cytostatic activity toward tumor cells. (B) Mitomycin C-treated bone marrow derived macrophages (BMDMs) had been stimulated for 24 h with various LPS concentrations just before addition of five,000 MOPC315 tumor cells/well, resulting inside the indicated macrophage to target cell ratios. The growth on the tumor cells was quantified by measuring incorporation of radiolabeled thymidine and is shown around the y-axis as imply counts per minute (cpm) values of triplicates ?SD. The three columns for the left show proliferation of BMDMs alone (tumor cells were not added). (c) BMDMs were stimulated with IFN- (40 ng/ml) in mixture with distinct concentrations of LPS.
