Representative images of PD-L1 IHC assays in TMA. Four PD-L1 IHC assays (28 − 8, 22C3, SP142, and SP263) were performed on TMAs consisting of 3 cores from each case. The images of the entire cores of TMA were generated by compositing sectioned images using All-in-one fluorescence microscope (BZ-X710, KEYENCE, Osaka, Japan). One representative example of a PD-L1-positive and PD-L1-negative case is shown. This positive case showed PD-L1 expression in both TCs and ICs. The bottom images are the high-powered field of PD-L1 staining in TCs and ICs, respectively. TC, tumor cells; IC, immune cell.
