Effect of hUCMSC or IFN-β-hUCMSC conditioned medium with or without IFN-β neutralizing antibody on the growth of H358 and SW1573 human lung cancer cell lines. H358 or SW1573 cells (3 × 105 cells/well) were seeded in 6-well plates. The conditioned medium was applied 24 hrs after initial cell seeding. In some cases, neutralizing antibody against IFN-β was added to the conditioned medium at 5.0 μg/ml. The cells were cultured for 72 hrs in the conditioned medium and the number of cancer cells was counted using a hemocytometer. Bar graphs indicate the average of two independent triplicate determinations. ***, p < 0.001 as compared to the level of untreated control. †, p < 0.01 as compared to the level of IFN-β-hUCMSC conditioned medium treated cells.
