Figure Lengend Snippet: Identification of key cell type, pseudotime trajectories, and dynamic biomarker expression. (A) bar plot showing differential proportions of cell clusters between PAH and control samples; (B) Bubble plot illustrating the expression levels of the five candidate genes across annotated cell types; bubble size indicates the percentage of expressing cells, and colour intensity reflects expression magnitude; (C) heatmap of pathway enrichment analysis in the identified key cell population; (D–F) Pseudotime trajectory analysis of the key cell type: each point represents an individual cell coloured by pseudo time (dark blue = early state; light blue = late state). Black circles with numbers denote distinct cell‐state nodes identified during trajectory inference; (G, H) dynamic expression changes of BECN1, HIF1A, MFN1, RRAS, and TAX1BP1 along pseudotime in macrophage subtypes, stratified by cell state; (G) and macrophage polarization (M1 vs. M2) (H) ; (I) Violin plots showing state-specific expression patterns of the five hub genes.
