MSC exosome isolation and characterization. a Exosomes were analysed by transmission electron microscopy by negative staining of phosphotungstic acid. b The size distribution of exosomes was analysed by NTA with Flow NanoAnalyzer. c Exosome markers CD9, CD63, CD81, HSP70, and Flotillin 1 were identified by the WB method. d Exosome markers CD9, CD63, and CD81 and e MSC markers CD73, CD90, and CD105 were analysed by flow cytometry.
