A METHOD FOR PRODUCTION OF NATURAL KILLER CELL

摘要

A method for preparing a natural killer cell is provided to treat cancer by obtaining the adult natural killer cell from an adult stem cell. A method for preparing a natural killer cell comprises the steps of: (a) treating an adult stem cell derived from cord blood of human with IL-7, SCF and Flt3L to be differentiated into a natural killer precursor cell; and (b) treating the natural killer precursor cell with Gas6. A transfectant comprises a recombinant vector pcDNA3.1(+)-GAS6.
