Schematic Representation of exosomes. The structure and contents of exosomes are demonstrated in this plot. The lipid bilayer membrane of exosomes, sharing similar topology to the original cells, carries typical transmembrane proteins and receptors. In addition, the contents of exosomes can be transferred from the original cell to their target cell, including RNA species (mRNAs, miRNAs, and other types of short RNAs) and a vast array of different proteins.
