Fig. 3. The CLDN2+ AT2 cells possess a stationary state.
a, b Pseudotime trajectories of malignant epithelial cells in patient P2 are colored by the pseudotime (a) and states (b). c Pseudotime trajectories splitted by epithelial cell subtypes in patient P2. d Box plot of differences in pseudotimes between AT2 and CLDN2+ AT2 cells. Wilcox test, unpaired. e Heatmap of the pseudotime-dependent expression alterations of epithelial subtype marker genes. f Pathway enrichment results based on the marker genes of each epithelial subtype. Colors represent different subtypes. P: hypergeometric distribution. g Violin plot of the expressions of CLDN2-relevant cellular senescence marker genes in different epithelial cell subtypes. h Violin plot of the differential expression of CLDN2-relevant cellular senescence marker genes between CLDN2+ AT2 cells from the tumor and normal tissues. Wilcox test, unpaired. ****P < 0.0001.
