Quality control and preprocessing of scATAC-seq data from burnt rat skin. (a) Violin plot showing the distribution of log10(nFragments) and TSS enrichment scores for each library, with libraries grouped by burn injury status and time points. (b) H&E-stained sections of rat skin under normal conditions and at various time points post-burn (0–19 days) (×20). Immune cell infiltration is observed in the early burn stage (≤3D), followed by extensive proliferation of fibroblasts and parenchymal cells (7D–11D) and extracellular matrix remodelling (15D–19D). (c) Heatmap showing the correlations between different libraries. (d) Scatter plot comparing log10(nFragments) and TSS enrichment scores, revealing the quality of the data. (e) UMAP plot visualizing the distribution of cells across different time points post-burn injury, with each dot representing a single cell and the colour indicating the time point. (f) Transcription start site (TSS) enrichment profiles for each library. (g) Bar chart showing the number of cells captured at each time point.
