Effect of hUCMSC and IFN-β-hUCMSC co-culture 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. After allowing the cancer cells to attach to culture dishes, either hUCMSCs or IFN-β-hUCMSCs (3 × 105 cells) were seeded in the cell culture inserts (3.0 μm pore size). The cells were cultured with hUCMSC growth medium for 72 hrs., and the number of cancer cells was counted using a hemocytometer. Bar graphs indicate the average of two independent triplicate determinations. *, p < 0.05, ***, p < 0.001 as compared to the level of untreated control.
