From: M1 macrophage-derived exosomes inhibit cardiomyocyte proliferation through delivering miR-155

Induction and identification of M1-Exos A) The particle size and concentration of isolated exosomes were detected using nanoparticle tracking analysis. B) The size and shape of macrophage-derived exosomes were observed by transmission electron microscopy. Scale bar: 200Â nm. C) Immunoblotting was performed with macrophage marker proteins calnexin and CD68, and exosome marker proteins CD81 and CD63. GAPDH served as a loading control. Each experiment in this figure was replicated more than three times
