From: Harnessing exosomes for targeted drug delivery systems to combat brain cancer
The endocytic process, the endosome process, and exocytosis are the three phases of the exosome process. When endocytosis occurs, the endosome gets tapped and matures into an older endosome that has numerous intraluminal vesicles (ILVs), or multi-vesicle bodies (MVBs). Exosomes represent the tiny vesicles that MVBs discharge into the external membranes
