A The t-SNE map depicting the cytotoxic cells (red) in the (a), tumor tissues (b), adjacent tissues, and (c) tissues from eight HCC patients. B Bar plot depicting the ratio of cytotoxic cells in the tumor tissues and adjacent tissues for each HCC patient. C–D Expression t-SNE maps for the T cell exhaustion markers LAYN and CTLA4 in the tumor tissues and adjacent tissues.
