Figure 5: The killing activity of mIFN-DCs is stronger than that of IFN-DCs and, particularly, mIL-4-DCs.

(a) CFSE-labelled K562 cells were incubated with indicated DCs at a ratio of 50:1 for 18 h. Incubated cells were subsequently subjected to flow cytometry and gated on a FSC and SSC dot plot to identify single cells. Subsequently, the gated cells were subgated according to CFSE and PI staining. DC killing activities are shown as percentages in the dot plot panels (representative of N = 11). (b) DC killing activity against K562 cells is indicated in the box plot (N = 11). *p < 0.05, **p < 0.01.
