Antitumor activities of human autologous cytokine-induced killer (CIK) cells against hepatocellular carcinoma cells in vitro and in vivo

Table 2 Inhibitory effects of CIK, PBMC and LAK cells on HCC cells in tumor-bearing nude mice

Group	n	Tumor/g	Tumorgenesis (%)	Inhibitory rate (%)
Control	9	2.10 ± 0.41	100	0
PBMC	11	1.32 ± 0.27	100	37.1
LAK	11	0.99 ± 0.33	100	52.8
CIK	15	0.32 ± 0.31	66.7	84.7ab

^aP < 0.05 vs LAK group,

^bP < 0.01 vs PBMC group.
