The characterization of exosomes from the Acute group and Chronic group. A Observation of electron micrographs of exosomes by transmission electron microscopy (TEM) (Bar = 100 nm). B Measurement of exosomes diameter using nanoflow cytometry (nFCM). C Measurement of exosomes concentration using nFCM. D Detection of surface markers CD9 and CD81 expression on exosomes using nFCM, with blank IgG used as a negative control.
