In contrast, PD-L1 overexpression was observed in CD90+CD73+ and CD90+CD73- tumor mesenchymal subsets in both LUAD (N, 506±570 vs T, 891±1263, p < 0.0001; and N, 309±386 vs T, 580±1088, p < 0.0001, respectively) and LUSC (N, 684±632 vs T, 1054±1237, p = 0.0013; and N, 391±448 vs T, 596±979, p = 0.0027, respectively) (Fig. S4e,f). Here, THY1 is linked to neoplasm.
