Adoptive T-cell immunotherapy is a promising approach to cancer therapy. Stem cell memory T (T-SCM) cells have been proposed as a class of long-lived and highly proliferative memory T cells. CD8(+) TSCM cells can be generated in vitro from naive CD8(+) T cells via Wnt signalling; however, methods do not yet exist for inducing T-SCM cells from activated or memory T cells. Here, we show a strategy for generating T-SCM-like cells in vitro (iT(SCM) cells) from activated CD4(+) and CD8(+) T cells in mice and humans by coculturing with stromal cells that express a Notch ligand. iT(SCM) cells lose PD-1 and CTLA-4 expression, and produce a large number of tumour-specific effector cells after restimulation. This method could therefore be used to generate antigen-specific effector T cells for adoptive immunotherapy.
