Induction of CTL response in tumor-bearing mice via immunization with unpulsed DCs, Pro-DCs or RNA-DCs. (A) CTL-stimulated lysis of CCSCs by pulsed or unpulsed DCs at E/T ratios of 10:1, 20:1 and 40:1. (B) Levels of IFN-γ secreted by CTLs derived from pulsed or unpulsed DCs against CCSCs at an E/T ratio of 20:1. The results represent three independent experiments. Data are presented as the mean ± standard deviation. *P<0.05 vs. PBS; #P<0.05 vs. unpulsed DCs; P<0.05 vs. RNA-DCs. CTL, cytotoxic T lymphocyte; DC, dendritic cell; Pro-DC, tumor lysate protein-pulsed dendritic cell; RNA-DC, tumor total RNA-pulsed dendritic cell; CCSCs, colon cancer stem cells; E/T, effector-to-target; IFN-γ, interferon-γ.
