Exosome is a kind of extracellular vesicles. Its lipid bilayer membrane vesicles carry multiple signal factors such as nucleic acid, protein, carbohydrate, lipid, etc., and act as a medium for signal transmission between cells to regulate physiology. And pathological mechanisms, making it a research and development of disease diagnosis and treatment has attracted attention. The unique biocompatibility of exosomes and the ability to carry different types of inclusions give them the potential to develop into a new generation of drug carriers.
