Abstract: A method for producing CAR-M1 macrophages expressing a chimeric antigen receptor in vitro and in vivo includes using a conjugate of a non-viral gene delivery system and a chimeric antigen receptor gene. The CAR-M1 macrophages are produced in vivo by delivering genes encoding a chimeric antigen receptor and IFN-?, specifically to macrophages in the body, and thus does not require culturing and preparing an in-vitro cellular therapeutic agent, thus reducing the manufacturing costs of therapeutic agents. The CAR-M1 macrophages are a safer therapy since a non-viral vector is used, as compared to the production of CAR-M1 macrophages by gene delivery using a viral vector, and are a novel therapeutic candidate having the advantage of high anticancer efficiency for solid cancers, due to CAR-M1 macrophages in which intrinsic properties of macrophages infiltrating solid cancers and cancer cell phagocytosis are improved.
