Proteomic analysis of exosomes. a Mass spectrometry analysis of exosomal proteins. Central star points to the two most abundant proteins, albumin (ALB) and alpha-2-macroglobulin (α2M). Blue boxes identify proteins involved in wound healing. b Western blot analysis confirming the expression of α2M in exosomes compared with fibroblast (Fibro) cells. c Western blot analysis confirming the presence of exosomes by detecting CD81 protein, a marker of exosomes.
