Abstract: A cell genetically engineered for activating natural killer (NK) cells. The genetically engineered cell for activating NK cells synergistically induces the proliferation and activation of NK cells in a sample, thereby producing effects that can be usefully utilized in a method of proliferating NK cells, a method of measuring NK cells proliferated by the method, or an activation degree of NK cells, or a method of diagnosing an NK cell activity-related disease. A feeder cell for culturing a natural killer (NK) cell, genetically engineered to express membrane bound interleukin-18 (mbIL-18) and membrane bound interleukin-21 (mbIL-21).
