Pluripotent stem cells are a promising source of T cells for a variety of clinical applications. However, current in vitro methods of T cell differentiation result in the generation of cells with aberrant phenotypes. Researchers at the National Cancer Institute (NCI) have now developed methodology for generating induced pluripotent stem cell thymic emigrants (iTE). Antigen-specific CD8αβ+ iTEs exhibited functional properties in vitro that were almost indistinguishable from natural naïve CD8αβ+ T cells, including vigorous expansion and robust anti-tumor activity. iTEs recapitulated many of the transcriptional programs of naïve T cells in vivo and revealed a striking capacity for engraftment, memory formation, and efficient tumor destruction. The NCI seeks licensing and/or co-development research collaborations for this invention.
Researchers at the National Cancer Institute (NCI) seek research & co-development and/or licensees for a novel, ex vivo method by which stem cell-like memory T cells (Tscm) can be generated by stimulating naïve T cells in the presence of inhibitors of GSK-3beta, which are capable of activating the Wnt pathway. These Tscm cells, generated using GSK-3beta inhibitors, display enhanced survival and proliferation upon transfer, have multipotent capacity to generate all memory and effector T cell subsets, and show increased anti-tumor activity in a humanized mouse tumor model.
