Abstract

CAR-T cell therapy has been increasingly conducted for cancer patients in clinical settings. Progress in this therapeutic approach is hampered by the lack of a solid manufacturing process, T lymphocytes, and tumor-specific antigens. T-cell source used in CAR-T cell therapy is predominantly derived from the patient’s own T lymphocytes, which makes this approach impracticable to patients with progressive diseases and T leukemia. Autologous CAR-T cell generation is time-consuming due to lack of readily available T lymphocytes and is not applicable for third-party patients. Pluripotent stem cells, such as human induced pluripotent stem cells (hiPSCs), could provide an unlimited T-cell source for CAR-T cell development. iPSC-derived T cells would be a promising infinite T-cell source and are phenotypically defined, expandable and functional as physiological T cells. iPSC-derived T cells provide a feasible T-cell source for the development of off-the-shelf T cells and CAR-T cells. The combination of iPSC and CAR-Technologies provides an extraordinary opportunity to oncology and greatly facilitates cell-based therapy for cancer patients. T-iPSCs in combination with CAR is in early stage of development and the pre-clinical and clinical studies concerning the combination of these novel technologies are not sufficient. This article critically reviews the progress in iPSC-derived T cell development and provides a roadmap for development of CAR iPSC-derived T cells and off-the-shelf T-iPSCs.
