OCPMB‐derived DC‐CIK cells significantly killed CD44+/CD133+ OCSCs. A, The cytotoxicity experiment results showed that the OCSC killing rates of CIK and the OCSC killing rate of DC‐CIK cells were both significantly higher than those in the simple OCSC group and the DC‐OCSC group at the 10:1 and 50:1 ratios; B, DC‐CIK cells and OCSCs were mixed at a ratio of 10:1 and cultured in vitro for 24 h. FACS results of Annexin V/PI staining showed that the total apoptosis rate in the DC‐CIK‐OCSC group was significantly higher than in the simple OCSC group and the DC‐OSCS group; C, The transwell invasion experiment results suggested that the number of migrated cells in the DC‐CIK‐OCSC group was significantly lower than those in the simple OCSC group and the DC‐OCSC group.
