The majority of immune cells acquire tumor material within the TME. (A) Experimental design, and representative flow cytometry analysis of ZsG fluorescence in CD45+ TILs isolated from B16 and B16ZsG tumors. (B–D) Total CD45+ TIL scRNA-seq data analyses. (B) UMAP visualization of scRNA-seq data from total (left), ZsG- (middle) and ZsG+ (right) TILs from B16ZsG tumors. The number of analyzed single cells are indicated in parenthesis. (C) UMAP plots of re-clustered monocytes/macrophages. (D) UMAP plots of monocyte (left) and macrophage (middle) signatures in re-clustered monocytes/macrophages with key marker genes in each cluster (right).
