ABSTRACT
Objective To study the anti-tumor effects of mixed cultured B16 melanoma cells supernatant.Methods The supernatant from purely cultured B16 melanoma cells or mixedly cultured B16 melanoma cells with lymphocytes and macrophages at indicated time points were collected,respectively.The chemotaxis of the two different cell supernatants was determined by Boyden room method.The activation effects towards lymphocytes of the two different supernatants were determined by CCK-8 method.Results When the cells were mixed cultured for 0.5,1,2,4,8 and 12 h,the numbers of lymphocytes to travel from the upper well to the bottom well were (1.00±0.82) × 104,(7.00±1.63) × 104,(9.50±0.58) × 104,(11.25±2.36) ×104,(17.25±1.71) × 104 and (21.50±1.29) × 104,respectively.When the cells were purely cultured for 0.5,1,2,4,8 and 12 h,the numbers of lymphocytes to travel from the upper well to the bottom well were (0.00±0.00) ×104,(0.25±0.50) × 104,(1.75±0.96) × 104,(5.25±0.96) × 104,(5.75±1.26) × 104 and (10.75±3.20) × 104,respectively.The mixed cultured group showed higher chemotaxis effects towards lymphocytes in comparison with the purely cuhured one at the same points except for 0.5 h (P < 0.05).The mixed cultured group showed higher activation effects towards lymphocytes in comparison with the purely cultured at the same points except for 0.5 and 1 h (P < 0.05).Each group showed higher chemotaxis and activation effects towards lymphocytes when they were cultured for 12 h than the other time points (P <0.05).Conclusion The supernatant from mixed cultured cells shows much higher chemotaxis and activation effects towards lymphocytes to kill tumor cells.
