Next, we characterized IFN-DC and cancer cell interactions and found that over 24–48 h single IFN-DCs exhibited a longer average interaction time with single cancer cells in RI relative to that in NT space (0–24 h: 16.1 min vs 14.9 min, 24–48 h: 11.5 min vs 8.7 min, 48–72 h: 11.6 min vs 12 min) (Fig. 5h). The gene discussed is IFNA1; the disease is cancer.
