T cells proliferation responses induced by dendritic cells. Magnetic cell sorting (MACS)-enriched CD3+ T cells were stimulated with autologous DCs pulsed with a DCs treated with tumor antigen pulsed nanoparticles fabricated using three different amounts (concentrations) of PVA, b Comparison of DCs pulsed with nanoparticles containing tumor antigen with those pulsed with either tumor lysate or NPs alone, at a ratios of 5:1, 10:1 and 20:1 for five days and proliferation rates were meassured by MTT assay. The triplicate proliferation indices from three patients were averraged and expressed as mean ±S.D (n = 3) (P 0.05)
