Nude mice injected with IL-18 gene engineered Bcap37 cell had no tumor growth.These findings indicated that human breast cancer cells were successfully modified by the gene of IL-18 cytokine;the IL-18 gene engineered Bcap37 cells secreted hIL-18 and lost their tumorigenicity.The Bcap37 cells transduced with IL-18 gene may be used as breast cancer vaccine.展开更多
