(a) Time-line for the growth inhibition assay used for measuring macrophage cytotoxic and cytostatic activity toward tumor cells. (B) Mitomycin C-treated bone marrow derived macrophages (BMDMs) have been stimulated for 24 h with many LPS concentrations prior to addition of five,000 MOPC315 tumor cells/well, resulting in the indicated macrophage to target cell ratios. The development with the tumor cells was quantified by measuring incorporation of radiolabeled thymidine and is shown on the y-axis as imply counts per minute (cpm) values of triplicates ?SD. The 3 columns towards the left show proliferation of BMDMs alone (tumor cells had been not added). (c) BMDMs had been stimulated with IFN- (40 ng/ml) in combination with distinct concentrations of LPS.
