“…CAR construct design and strategies by which CAR-T cells can be engineered to promote fitness, persistence, and antitumor efficacy have been reviewed in detail in several recent articles ( Gao and Chen, 2022 ; Hamieh et al, 2023 ; Hou et al, 2021 ; Labanieh and Mackall, 2023 ). Here, we focus our attention on autologous CAR-T cell manufacturing, which plays a critical role in the clinical impact of CAR-T cell therapy by influencing the phenotype and function of the CAR-T cell products ( Ceppi et al, 2022 ; Wang and Rivière, 2022 ). Although many of the aspects discussed in this review also apply to the manufacturing of allogeneic CAR-T cells, additional considerations exist for the engineering of donor T cells or the differentiation of stem cells into T-cell products, and discussions on these topics can be found in several excellent articles ( Depil et al, 2020 ; Jing et al, 2022 ; Seet et al, 2017 ; Themeli et al, 2013 ; Ueda et al, 2023 ; van der Stegen et al, 2022 ).…”
