Fig. 4: Single-Cell transcriptional analysis unravels heterogeneity of fibroblasts during FHP.A t-SNE visualization of PLA2G2Ahigh fibroblasts, COL1A1high fibroblasts, TCF21high fibroblasts, and ACTA2high fibroblasts. B The heatmap showing the expression levels of top five marker genes in fibroblast subpopulations. C Relative percentage of fibroblast subpopulations in lung from the patient with FHP. D Violin plots displaying the expression levels of the representative genes in each fibroblast subpopulation. E Relative gene set enrichment scores of subpopulations calculated by AUCell analysis. F Multiplex immunofluorescence images of TCF21, ACTA2, and COL1A1 in lung tissues from FHP. Scale bar = 10 μm. G Trajectory analysis of PLA2G2Ahigh fibroblasts, COL1A1high fibroblasts, TCF21high fibroblasts, and ACTA2high fibroblasts using Monocle 2 (upper) and Velocyto R package (lower). H CEBPD_extended motif showed greater enrichment of regulon activity for PLA2G2Ahigh fibroblasts using SCENIC analysis (left panel). MEF2C_extended motif showed greater enrichment of regulon activity for ACTA2high fibroblasts (left panel). t-SNE visualization of AUC values of CEBPD_extended and MEF2C_extended motifs in fibroblasts (right panel). I Schematic developmental trajectories of fibroblast subpopulations in FHP lungs. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
