Despite no difference in the presence of the Lin-EpCAM-CD73+CD90+ mesenchymal subset between tumor and matched normal, there was a significant difference in the expression level of PD-L1 (MFI 724 ± 767 versus 384 ± 409, respectively, n = 13, p < 0.0266, Fig. 2H). This evidence concerns the gene THY1 and neoplasm.
