Abstract: A method for producing natural killer cells is disclosed. The method comprises isolating peripheral blood mononuclear cells (PBMCs) from a blood sample; isolating at least one of CD56+ cells and/or CD3?/CD56+ cells from the PBMCs; and co-culturing the at least one of CD56+ cells and/or CD3?/CD56+ cells with a combination of feeder cells in the presence of a cytokine. A composition for treating cancer is also disclosed. The composition comprises the CD56+ natural killer cells produced by the disclosed method and a cytokine.

Abstract: The present invention relates to a method for inducing and expanding natural killer cells derived from peripheral blood mononuclear cells, which comprises co-culturing, as feeder cells, irradiated Jurkat cells and irradiated Epstein-Barr virus transformed lymphocyte continuous line (EBV-LCL) cells in the presence of cytokines, along with peripheral blood mononuclear cells. According to the present invention, a large quantity of natural killer cells can be induced and proliferated from a small quantity of peripheral blood mononuclear cells even without the use of high-cost equipment or various kinds of expensive cytokines, thereby making it possible to significantly improve the efficiency and efficacy of the prevention and treatment of cancer using the natural killer cells.
