'Here, we developed a multi-tumor mouse model system to track hundreds of expanding and contracting CD8+ T cell clones over multiple timepoints in tumors of the same individual. Through coupling of clonal expansion dynamics and single-cell RNA/TCR-seq data, we identified a transcriptomic signature in PD-1+Ly108+ precursor exhausted cells that strongly predicts rates of intratumoral clone expansion in mice and humans.'
