T cells generated by DC transfected with GPC-3 mRNA are functional in vitro. PBMC were depleted of HLA class II positive cells and co-cultured with autologous, γ-irradiated, LPS matured DC in serum-free X-Vivo medium supplemented on days 1, 3 and 7 of culture with IL-2 (20 U/ml) and IL-7 (10 ng/ml). After 7 days, T cells were re-stimulated with the same DC for a further 5 days. a. T cell proliferation (1 × 105/well) was measured by 3H-thymidine incorporation, T cells were cultured alone, with DC (1 × 104/well) transfected with 20 μg GPC-3 mRNA, or mock transfected DC. b. ELISPOT assay for interferon-γ production was performed on T cells (1 × 105/well) stimulated by DC transfected with 20 μg GPC-3 mRNA or mock transfected DC.
