PD-L1 expression in KTs. (a) Representative samples of HE and IHC staining of PD-L1 were shown, including tumor cells, stromal cells, and PD-L1-negative tumors. (b) Multiplex IHC of PD-L1 and CD8 on tumor cells and stromal cells. Nuclei were stained with DAPI. (c) The percentage of the tissue displaying positive and negative tumor and immune stromal PD-L1 staining in KTs from the GCs and CRCs. MT: metastasis.
