Figure 4. Comparison of CIK lysis potential against tumour cells.

Figure 4

Lysis rates of control CIKs compared with those of cCIKs against fibrosarcoma cells (Wehi 164 S) on day 14 for different effector-cell/target-cell ratios. Error indicator represents standard error of the mean. Initially, lysis rates increased with increasing effector-cell/target-cell ratio up to a lysis rate of 27% at a ratio of approximately 30∶1. Further increases in the ratios did not increase lysis rates further. No significant differences were observed between control CIKs and cCIKs (p>0.1).
