Schematical illustration of the exosome biogenesis. (A) the cell membrane forms early endosomes in the form of endocytosis. (B) the early endosomes mature into MVB containing exosomes after further acidification. (C) the MVB fuses with the cell membrane and releases exosomes into the extracellular space in the form of exocytosis.
