Characterization of NP exosomes. (a, b) Representative electron microscopy image of NP-exo and Ctrl-exo. (c) Western blot analysis of exosomal markers, GM130 was used as a nonexosomal marker; flotillin-1 was used as a loading control. (d–f) Nanoparticle tracking analysis displayed the size distribution of exosomes isolated from NLF.
