Figure Lengend Snippet: Verification of gp70 expression in CT26 cells and tumors. (A-D) Immunofluorescence staining. CT26 cells showed positive staining with rabbit-anti-mouse AH1 antibody (green cytoplasm). (A) The nuclei were stained using 7-AAD (red). (B) Murine 4T1 cell line served as the negative cell control. (C) CT26 cells were stained with peptide-adsorbed Ab. (D) CT26 cells were stained with rabbit IgG as the negative reagent control (A-D, ×40). (E) Western blot analysis of gp70 expression. 1, CT26 cell lysate; 2 and 5, CT26-derived tumor lysate; 3, murine 4T1 cell lysate (as the negative cell control); 4, normal murine muscle tissue lysate (as the negative tissue control); 6, CT26 cell lysate treated with rabbit IgG (as the negative reagent control); 7, CT26 cell-derived tumor lysate treated with rabbit IgG (as the negative reagent control). The 90 kDa band corresponds to gp90, the precursor of gp70.

Figure Lengend Snippet: Effect of various DC-based vaccination protocols on tumor size. Mice were inoculated subcutaneously with CT26 tumor cells (day 0). On days 3 and 10, mice were injected with DCs loaded with different Ag mixtures, shown in the figure. The tumor volume in all vaccination groups was measured from day 0 at 3-day intervals for 42 days. DC, dendritic cell; Ag, antigen; OVA, ovalbumin. a) As of day 18, the average tumor volume in tumor-bearing mice vaccinated with either DC-Pep or DC-Pep-OVA was significantly smaller than in those treated with DCP15-OVA, with naïve DC (DC-alone), or not treated at all (tumor), b) From day 36 and beyond, a significant difference in terms of tumor size was observed between the DC-Pep and DC-Pep-OVA groups. Data are shown as the average tumor volume of five mice per group on each day.

Figure Lengend Snippet: The therapeutic impact of DC-based vaccination on the survival rate of tumor-bearing mice. Groups of 10 mice were inoculated subcutaneously with CT26 tumor cells (day 0). On days 3 and 10, mice were injected with DCs loaded with different Ag mixtures, shown in the figure. The survival rate of all groups was determined weekly for 10 weeks and expressed as the percentage of live mice per treatment group. Significantly higher survival rate was observed in DC-Pep-OVA-treated mice compared to those vaccinated with DC-Pep. DC, dendritic cell; Ag, antigen; OVA, ovalbumin.
