GAMMA DELTA T CELLS DERIVED FROM INDUCED PLURIPOTENT STEM CELLS, AND PRODUCTION METHOD THEREFOR

Provided is a γδT cell for securing the purity and number of cells sufficient for treatment. Also provided is a method of generating the γδT cell. More specifically, provided are homogeneous γδT cells excellent in that the γδT cells are not affected by exhaustion of the cells. The foregoing is achieved by γδT cells obtained by subjecting induced pluripotent stem cells (iPS cells) to differentiation induction treatment. Specifically, the foregoing is achieved by γδT cells generated by subjecting iPS cells having a rearranged γδTCR gene (γδTCR-type iPS cells) to differentiation induction treatment. According to the method of generating the γδT cell of the present invention, there can be provided γδT cells and a cell population of γδT cells that have an excellent function of having antigen-specific cytotoxic activity in a MHC-unrestricted manner, and that are more homogeneous and have a higher effect than γδT cells separated from peripheral blood.
