  • Publication number: 20210238550
    Abstract: The present invention provides a method for producing a regenerated T cell population via iPS cells, wherein the said regenerated T cell population maintains the repertoire diversity of a T cell population before initialization and has specificity to an antigen. The method comprises steps of (1) bringing a T cell population into contact with one or more tumor-related antigens, or a biological tissue containing one or more tumor-related antigens, or a crushed material or a lysate thereof, and enriching the T cell population having specificity to the tumor-related antigens, (2) initializing the enriched T cell population to iPS cells, and culturing while maintaining the repertoire diversity of the enriched T cell population, and (3) producing a regenerated T cell population from the cultured iPS cells.
