Part II The experiment study on anti-tumour effect of dendritic cells derived from peripheral blood monocyte of patients with oral cancer after pulsed by tumour antigen in different ways. Collected 50ml peripheral blood from each patients and volunteers to induced DC in vitro. We parted the test group and control group into three subgroups respectively, untreated group A, freezed and thawn group B, RNA transfected group C. To group A, after induced DCs for five days , we added 200U/mlTNF-α in each hole and cultured on. To group B, we added protein antigen (DC/ tumor cells = 1 : 1 ,each hole) for 4h at 5d, and then added 200U/mlTNF-α in each hole and cultured on. To group C, transfected immature DC with tumor cell RNA(DC:RNA=1×105/ml: 5ug)at 5d, operated completely with the specification of invitrogen DMRIE-C reagents. After transfection we replaced transfection agent with complete medium, and then added 200U/mlTNF-α in each hole and cultured on.
