CAR-T cell therapy has shown great efficacy in the treatment of hematological malignancies and even solid tumors and chronic viral infections, thus considering to be one of the most promising cancer immunotherapies. While some limitations need to be improved for making common CAR-T cells. For conventional CAR-T cell therapy, it’s very expensive since it’s specific for the patients. T cell is derived from the patients and then engineered to become CAR-T cell which will be injected back into the patient (see Fig.1). Hence, exploring novel strategies to generate conventional naïve T cells is meaningful to facilitate universal, off-the-shelf CAR-T cell products.

Based on the reported method to generate conventional T cells from human pluripotent stem cells (see Fig.2), our scientists are dedicated to establishing this platform which enables the potential to transform autologous T cell immunotherapy to universal, off-the-shelf cell products. We established the pluripotent stem cell (PSC)-artificial thymic organoid system to generate mature, functional T cells from human PSCs. We used this system to successfully generate naive CD3+CD8αβ+ and CD3+CD4+ conventional T cells with a diverse T cell receptor (TCR) repertoire. When an MHC class I-restricted TCR was introduced in PSCs, naïve and antigen-specific CD8αβ+ T cells can be produced. For this kind of CD8 T cells, there is no endogenous TCR expression, and they showed anti-tumor activity both in vitro and in vivo. This characterization ensures the generated T cells are functional and can be used for universal, off-the-shelf CAR-T cell products.

This method is an efficient and standardized organoid system which can induce hematopoietic specification and conventional naïve T cell generation. Also, it enables the generation of naïve, antigen-specific T cells which hold anti-tumor activity.
