A Representative transmission electron microscopy (TEM) images. TEM demonstrates that isolated samples consisted of vesicles with typical membrane morphology. B Representative nanoparticle tracking analysis (NTA) of isolated exosomes. NTA indicates that most vesicles had a size of 30–150 nm in diameterBack to article page
