Fig. 1From: The effect of the WKYMVm peptide on promoting mBMSC secretion of exosomes to induce M2 macrophage polarization through the FPR2 pathwayThe cytotoxicity of WKYMVm peptide on mBMSC at 24, 48, and 72 h. a Morphology of mBMSCs under optical microscope. b The proliferation of mBMSCs, treated with WKYMVm peptide (1 μmol/L), was detected by CCK-8. Data represent means ± SD. N.S relative to controls in which the concentration of WKYMVm peptide was 0 μmol/LBack to article page
