Isolation and identification of exosomes derived from bone marrow mesenchymal stromal cells (BMSCs, BMSCs-EXO), as well as synthesis and characterization of DSPE-PEG-CMP-EXO and DSPE-PEG-CMP-miR302-EXO. A Morphological characteristics of BMSCs-derived exosomes (BMSCs-EXO) was observed under transmission electron microscope (TEM). Scale bar = 100 nm. B The size distribution of BMSCs-EXO was measured via the Nanoparticle tracking analysis (NTA). C Flow cytometric technique was used to analyze the specific surface markers (CD44, CD45, CD29 and CD73) of BMSCs of BMSCs-EXO. Scale bar = 100 nm. D TEM morphology of DSPE-PEG-CMP-EXO. E NTA measured size distribution of DSPE-PEG-CMP-EXO. F TEM morphology of DSPE-PEG-CMP-miR302-EXO. Scale bar = 200 nm. G The size distribution of DSPE-PEG-CMP-miR302-EXO was measured with the NTA
