Extended Data Fig. 7: TGFβ1 exposure drives transcriptional similarity to exhausted CD8+ T cells in human cancer.

(a) UMAP visualization of CD8+ T cell meta-clusters identified in single-cell RNA-seq analysis of human CD8+ T cell subsets including tumor-infiltrating lymphocytes (TILs) from 21 types of human cancer (GSE156728)45 (b, c) UMAP visualization showing RNA expression levels of some selected signature genes in human TILs and memory CD8+ T cell clusters that overlap with transcriptional features of in vitro-differentiated Dysfunctional and Treated human CD8+ T cells.
