Abstract: The present invention pertains to a method for culturing cord blood-derived natural killer cells using transformed T-cells. The method for culturing natural killer cells using transformed T-cells according to the present invention can effectively propagate and produce natural killer cells from a small amount of raw cells. In addition, the method can also improve the cell-killing ability of natural killer cells. Thus, the method for culturing natural killer cells using transformed T-cells according to the present invention can be usefully used to commercialize cell therapeutic agents. Moreover, natural killer cells produced by the culturing method of the present invention can be usefully used as a cell therapeutic agent.

Abstract: The present invention relates to a method for producing natural killer cells using T cells, and more particularly, to a method for producing natural killer cells, which comprises culturing seed cells using CD4 (+) T cells as feeder cells. The method for producing natural killer cells using T cells according to the present invention is a method capable of producing natural killer cells by selectively proliferating only natural killer cells from a small amount of seed cells while maintaining the high killing activity of the natural killer cells. The method of the present invention can produce a large amount of natural killer cells that can be frozen, and thus is useful for commercialization of cell therapeutic agents.

Abstract: The present disclosure relates to a method for producing natural killer (NK) cells. More specifically, the present disclosure relates to a method for producing NK cells, characterized in that peripheral blood mononuclear cells from which CD3-positive cells are removed are proliferated together with feeder cells, and the peripheral blood mononuclear cells are re-stimulated with feeder cells at the time of reaching a specific accumulated population doubling level. The present disclosure also relates to a method for producing NK cells, characterized in that NK cells are cultured under appropriate culture conditions by using a bioreactor. The production method according to the present disclosure has an advantage that NK cells having a high cell-killing ability and cell survival rate can be produced with high purity and at high efficiency in a short period of time by a clinically friendly method as compared with existing methods, thereby increasing the productivity of an NK cell therapy agent.

Abstract: A method for culturing natural killer cells uses genetically modified T cells. The method for culturing natural killer cells, using genetically modified T cells enables the effective proliferation and production of natural killer cells from a smaller amount of source cells. In addition, the method enhances the cytolytic activity of natural killer cells. Therefore, the method for culturing natural killer cells, using genetically modified T cells may be suitable for various applications in commercializing cell therapy products. Further, the natural killer cells produced by the culturing method can be useful as a cell therapy product.
