Figure Lengend Snippet: Endothelial cells (ECs) are sorted by anti-CD31 magnetic beads and used for subsequent detection. A The mRNA levels of Ccr10 in ECs treated with mouse recombinant CCL28 protein (rCCL28) at different concentrations for 24 h were determined by RT-qPCR (biological replicates, n = 4 per group, One-Way ANOVA using Tukey multiple comparisons test). B Flow cytometry-based representative dot plots and quantification of CCR10 + ECs treated with rCCL28 at different concentrations (biological replicates, n = 4 per group, One-Way ANOVA using Tukey multiple comparisons test). C Gene set enrichment analysis (GSEA) for endothelial cells isolated from hearts of the Ccl28 -KO (KO) and littermate control mice (WT) mice subjected to MI surgery at 3 days, as tested by RNA-sequencing. D Representative bands of p-ERK1/2, ERK1/2, VEGFA, SOX5, CCR10 and ACTB protein measured by Western blot assay (biological replicates, n = 3 per group). E Representative bands of SOX5, CCR10 and ACTB protein measured by Western blot assay (biological replicates, n = 3 per group). F Western blot analysis of input proteins and proteins immunoprecipitated with either IgG or SOX5 antibody. G ChIP analysis of the Ccr10 promoter site 3 (−400 to +200) in ECs by RT-qPCR (biological replicates, n = 3 per group, Unpaired two-tailed Student’s t -test). H Dual-luciferase reporter assay was performed after co-transfection with a reporter vector in NIH/3T3 (biological replicates, n = 4 per group, Two-Way ANOVA using Tukey multiple comparisons test). I , J The sprouting ability (biological replicates, n = 4 per group, Unpaired two-tailed Student’s t -test. scale bar, 100 μm) and K aging proportion (biological replicates, n = 4 per group, Unpaired two-tailed Student’s t -test. scale bar, 250 μm) of ECs were measured. L Mechanism diagram of CCL28-induced CCR10/ERK/SOX5 positive feedback signaling. Data are expressed as mean ± SD. Source data are provided as a Source Data file.
Article Snippet: After incubation with TruStain FcXTM antibody (101320, Biolegend) for 15 min to minimize non-specific binding, cells were then stained with the following antibodies for 30 min. For detection of CCL28 + cells: AF488 anti-CCL28(sc-376654, Santa Cruz), APC/FireTM 750 anti-CD45 (103154, Biolegend), PE/Cy7 anti-CD31(102524, Biolegend), APC anti-CD140a (135908, Biolegend), PE anti-Ly6C (128008, Biolegend), PerCP/Cyanine5.5 anti-Ly6G (127616, Biolegend), PE/Cy7 anti-CD11b (101216, Biolegend), APC anti-F4/80(123116, Biolegend).
