Subpopulation and functional enrichment analysis of fibroblasts. A UMAP shows that fibroblasts can be clustered into three subpopulations. B UMAP plot showing the expression of three typical genes (MMP11/HLA-DRB1/VEGFA) in three fibroblast subpopulations. C Heatmap showing top 5 highly expressed genes in each subpopulation of fibroblasts. D–F Bar plot showing top 5 terms or pathways significantly enriched for HLA-DRB1 + CAF, MMP11 + CAF, VEGFA + CAF. G Heatmap showing the different subtypes of fibroblasts' progeny pathway scores. H Box line plots showing the scores of basement membrane, interstitial collagen, collagen, ECM glycoproteins, and proteoglycans in comparison for three subpopulations of fibroblasts. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001
