doi: 10.1038/s41536-024-00362-2

Figure Lengend Snippet: a Male EPC CM containing high levels of inflammatory cytokines promoted greater migration of monocytes at 18 h of inducing them in a scratch assay in vitro. b , c Inhibition of CCL3 using CCL3-neutralizing polyclonal antibody (CCL3-N-pAb) in M-EPC CM significantly inhibited the migration of monocytes. c Lower migration of monocytes was promoted by F-EPC and OVX-EPC. Inhibition of CCL3 in F-EPC and OVX EPC had low or no effect on monocyte migration. F-EPC and OVX-EPC CM promoted polarization of monocytes into a macrophage M2-like phenotype, resulting in upregulated expression of Arginase 1 ( d ), IL-10 ( e ), and VEGF ( f ). Male EPC did not promote alternative switching of monocytes to the M2 phenotype. d – f TNFα was used on activated monocytes to induce the M1 phenotype switch as a positive control. IL-4 and IL-10 stimulated monocytes were used as a positive control for the M2 phenotype. g , h significantly high numbers of CD206 high M2 cells were found in heart tissue sections of mice injected with F-EPC and OVX-EPC compared with the M-EPC injected group. Vehicle and sham hearts were also stained with CD206 as controls. * P < 0.01; ** P < 0.001; *** P < 0.0005; **** P < 0.0001; scale bar = 20 μm. Data are shown as mean ± s.e.m. n = 3–7.
