Figure Lengend Snippet: Fig. 2. The acute inflammation rather than type II immune response around ECM scaffold membrane in aged wounds. (a) Schematic diagram for generating the scRNA-seq and spatial transcriptomics data from ECM mediated wound healing at POD7 in young and aged mice. (b) The UMAP reduction results reveals 13 different cell types in wounds. The marker genes are listed on the right of the annotation. (c) The annotated clustering results for spatial transcriptomic based on the anatomic structure of the wounds. (d) The proportion of each cell type of the whole wounds and their related wound healing process. (e) The upregulated results for Gene Sets Enrichment Analysis (GSEA) in ECM scaffolds treated aged wounds. (f) The AddModule scores of acute inflammation term in spatial transcriptomics expression. (g) The IF results for INOS and LY6G in Young_ECM and Aged_ECM at POD7. (Scale bars at the same column are the same) (h–i) The semiquantitative analysis of INOS and LY6G fluorescence area in (g) respectively. **P < 0.01 and *P < 0.05 by Student’s t-test (n = 5) for data in (h) and (i).
