Dendritomas formed by fusing cancer cells to dendritic cells have already been applied to clinical treatment trial of several types of cancers. Dendritic cells for the fusion in most trials and experiments were from blood monocytes in standard 7-d protocol culture, which requires 5-7 d of culture with granulocyte-macrophage-colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4), followed by 2-3 d of activation with a combination of proinflammatory mediators such as tumor necrosis factoralpha (TNFalpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and prostaglandin E(2) (PGE(2)). One study showed that mature monocyte-derived dendritic cells could be obtained within 48 h of in vitro culture with the same protocol as standard 7-d culture and referred to as FastDCs. Here we aimed to fuse human hepatocellular carcinoma cell line HCCLM3 cells with mature monocyte-derived dendritic cells within 48 h of in vitro culture (FastDC).
