Fig. 2: Identification and characterization of high-stemness malignant GC cells.

A Heatmap of CNV signals across epithelial clusters. B Violin plot shows CNV score differences among epithelial clusters. C CytoTRACE plot displaying stemness score distribution in malignant epithelial cells. D Histogram of CytoTRACE score-based subgroup classification: LowStem, DTStem, and HighStem. E UMAP visualization of malignant cells colored by stemness subgroups. F Box plot comparing CytoTRACE scores among subgroups. G UMAP showing scPagwas-derived tumor relevance scores (TRS). J UMAP plots of stemness score, TRS score, and their combined distribution. H Box plot of TRS scores among stemness subgroups. I Correlation between CytoTRACE stemness scores and TRS values.
