Disclosed is a method for producing a large amount of natural killer cells and the use of the natural killer cells as an anticancer agent. The method produces fresh NK cells with high purity within a short time, and can also produce cold-preserved NK cells and thawed cryopreserved NK cells having efficacy comparable to the fresh NK cells. NK cells having efficacy comparable to the fresh NK cells can also be produced from cryopreserved CD3-negative cells. The fresh NK cells, cold-preserved NK cells and cryopreserved NK cells exhibit therapeutic effects against various cancers, including colorectal cancer, lung cancer, liver cancer, pancreatic cancer and leukemia, indicating these NK cells are effective as cellular therapeutic agents. Also disclosed are doses and methods of administration that show excellent effects when the fresh NK cells, cold-preserved NK cells and cryopreserved NK cells are used as pharmaceutical compositions for cellular therapy.

Disclosed are a natural killer (NK) cell expressing an anti-cotinine chimeric antigen receptor (CAR) specifically binding to cotinine, and a cell therapeutic agent containing the NK cell. The CAR-expressing NK cell which specifically binds cotinine, can effectively move to tumor tissue, regardless of the kind of cancer, depending on the binding substance bound to cotinine. Therefore, the natural killer cell can be usefully employed as a gene therapy exhibiting a highly efficient anticancer effect.
