Figure Lengend Snippet: IL-4 and Arg remodel macrophages and promote their migration (A) Schematic illustration of the regulatory role of IL-4 on macrophage phenotype. (B) Volcano plot displaying differentially expressed genes (DEGs) between the control and IL-4-treated macrophages. (C) Heatmap demonstrating the expression of key macrophage polarization markers. (D) Multi-pathway Gene Set Enrichment Analysis (GSEA) demonstrating the integrated enrichment of indicated pathways regulating macrophage functions. (E) Schematic illustration of macrophage priming for efferocytosis mediated by IL-4 and Arg. (F) Relative cell viability of macrophages treated with different concentrations of Arg at 24, 48, and 72 h. (G and H) Macrophage proliferation evaluated by 5-ethynyl-2′-deoxyuridine (EdU) assay, showing representative fluorescence images of EdU and 4',6-diamidino-2-phenylindole (DAPI) staining at 24, 48, and 72 h (G) and quantification of EdU-positive cells treated with 2 mM Arg (H). (I) Schematic illustration of the Transwell migration assay. (J and K) Macrophage recruitment evaluated by Transwell assay, showing representative crystal violet staining images of migrated macrophages after 48 h (J) and quantification of the number of migrated macrophages (K). Error bars represent SD. Data were analyzed by two-way ANOVA followed by Sidak’s multiple comparisons test (F and H) or one-way ANOVA followed by Tukey’s post hoc test (K). Sample sizes: n = 3 biological replicates (B–D and F); n = 5 biological replicates, each performed with 3 technical replicates (G, H, J, and K). Scale bars, 25 μm (G), 500 μm (J, top), and 100 μm (J, bottom).

Article Snippet: Nuclei were counterstained with DAPI (Beyotime) for 10 min. All staining was performed at room temperature in the dark.
