Abstract: Provided herein are methods for preparing T cells for T cell therapy comprising contacting a cell population at a predetermined cell density, with a concentration of an anti-CD3/CD28 nanomatrix and culturing the cells thereby producing a T cell population comprising an increased percentage of at least one T cell subtype. In some embodiments, the method increases the percentage of stem memory T cells.

Abstract: Provided herein are improved methods for transducing immune cells, such as T cells, with retroviral vectors to express exogenous gene products, such as chimeric antigen receptors (CARs). Provided herein are methods that increase transduction efficiency thereby increasing the percentage of immune cells in a population expressing the exogenous gene product. Associated cells, cell populations, compositions and methods of use are also provided.

Abstract: Provided herein are improved methods for robust TCR+ cell depletion and production of populations of TCR− cells, which can be beneficial to minimize the GvHD risk in patients receiving allogeneic CAR T cell therapy. Provided herein are methods that increase the efficiency of depleting TCR+ cells from a population of cells in order to significantly reduce any residual levels of TCR+ cells present in cell populations in which expression of endogenous TCR has been reduced or eliminated. Associated kits and cell populations are also provided.
