Single-cell RNA-seq of gastric tumor and non-malignant samples. (A) UMAP maps of non-atrophic gastritis (NAG, n = 3) and primary tumor (PT, n = 11). (B) UMAP mapped the single-cell identification of different cell clusters in samples. (C) Dot plots of marker gene expression levels in each cell type. (D) UMAP plot showing the expression levels of canonical marker genes for nine cell types. (E) The proportion of each cell type in 14 samples.
