Prevention of Prostate Tumor Development by Stimulation of Antitumor Immunity Using a Standardized Herbal Extract (Deep Immune®) in TRAMP Mice

Figure 6

The tumor-killing activity of splenocytes from mice after treatment with the DI. The splenocytes from TRAMP mice (pretreated/onset, untreated control, or extract-treated) as indicated in Table 2 were cocultured with mouse prostate tumor cells (TRAMP-C2) at different ratios for 24 h, and the tumor-killing activity was determined by the percentage of Calcein-AM release in Calcein-AM release assay. The data were presented as mean of the standard error of mean (SEM) of each group (control versus onset, ; extract versus onset, ; extract versus control, , two-way ANOVA, –12).
