Single-cell landscape of the GC tumor environment. (A) UMAP of the GC single-cell landscape annotated by cell type. (B) Dot plot showing selected genes for each cell type. Dot size indicates the percentage of expressing cells, colored on the basis of average expression. (C) UMAP plots showing the expression of known marker genes. (D) Fraction of cell types originating from normal gastric tissues and the superficial and deep GC layers. (E) GSEA of the DEGs in epithelial cells between cancerous and normal gastric tissues. (F) GSEA of the DEGs in epithelial cells between the deep and superficial GC layers.
