Vaccine-induced antitumor immunity in vivo. a The hydrogel vaccines accelerated DC maturation (CD11c+CD80+CD86+) in the tumor examined 3 days post treatment. Data represent mean ± s.d. (n = 3). b Flow cytometric examination of the intratumoral infiltration of CD4+ and CD8+ T cells (gated on CD3+ T cells). Data represent mean ± s.d. (n = 3). c Tumor mass-normalized intratumoral infiltration of CD8+ T cells in the recurrent tumors examined 10 days post treatment. The comparison of two groups was followed by Unpaired student’s t-test (two-tailed). ***p < 0.01. Data represent mean ± s.d. (n = 3). d The frequency of Tregs in the recurrent tumors after different treatments examined 10 days post treatment. Data represent mean ± s.d. (n = 3). e The proliferation activity of CD8+ T cells in the recurrent tumor examined 10 days post treatment. f The frequency of TNF-α+/IFN-γ+ CD8+ T cells in the recurrent tumors after different treatments examined 3 days post treatment. g Ratios of tumor-infiltrating CD8+ T cells vs. Tregs in the recurrent tumor examined 10 day post the first treatment. eg The significance of the deferences was evaluated by one-way ANOVA. ***p < 0.01. Data represent mean ± s.d. (n = 3)
