Representative images of co-expression of B7-H4 and IDO1 and the enrichment of Tim3-positive and VISTA-positive cells in the stroma. A and B: Co-expression of B7-H4 and IDO1 in membrane and cytoplasm of tumor cells, indicated by white arrows. Panels in B are magnifications of lined areas in A. C: Circled are clustered immune-suppressing stromal cells that were positive for Tim3 and VISTA and negative for CD8. These stromal cells were distributed close to the tumor cells positive for B7-H4 and IDO1. Bars, 50 μm.
