Characterization of AMSCs derived–exosomes. (A) Immunoblotting of AMSCs-derived exosomes, Exoquick-derived supernatants (SN) and AMSCs lysate for CD9, CD63, CD81 and TSG101 exosomal protein and Calnexin, GRP94 and RISC contaminants (cropped images – uncropped originals available in Supplementary Figure 2). (B) The concentration of exosomes was quantified measuring the enzymatic activity of the exosomal AChE enzyme by Exocet kit. Particles size were quantified by qNano system (D) and a representative graph of frequency size distribution is shown (C). Columns, mean; bars, SD.
