As shown in Fig. 2 (from patient1), purified hybrids, the adherent cell fraction, the non-adherent cell fraction, total fusion products, and purified hybrid cells supplemented with the non-adherent cell fraction significantly induced T cell proliferation (P<0.05) compared to adherent tumor cells, DCs mixed with tumor cells, DCs, or IL-2 alone. Here, IL2 is linked to neoplasm.
