Stimulation of DC-CIK with PADI4 Protein Can Significantly Elevate the Therapeutic Efficiency in Esophageal Cancer
Figure 5
Detection of CIK cell proliferation, viability, and cytotoxicity. CIK cells were induced with DCs loaded with rPADI4. CIK cells induced with d-rPADI4-loaded DCs were used as a control. (a) The number of CIK cells was counted following coculture with DCs. (b) The viability of CIK cells was analyzed following coculture with DCs. (c) A CCK8 kit was used to determine the cytotoxic effect of DC-CIK cells on the cultured ECA-109 tumor cells. CIK cells induced with d-rPADI4-loaded DCs were used as a control. Asterisks indicate significant differences between the two groups. indicates .
