Objective To explore the effect of livin-targeted siRNA on the cell proliferation and the production of tumor necrosis factor-α(TNF-α)in the isolated CD133-positive cancer stem cells from TJ905 cells.Methods CD133 positive cells were isolated from TJ905 cells by immunomagnetic beads technique.Livin-targeted siRNA was constructed and transfected into cancer stem cells by the mediation of lentivirus.Lentivirus alone was transfected into cancer stem cells to serve as blank control.After transfection,the cells ...
