Exosomes as promising frontier approaches in future cancer therapy

Figure 1 Schematic diagram of approaches for cargoes loading to exosomes. The scheme illustrates the approaches including biological, chemical, and physical methods, which are used to load cargoes, such as drugs, RNA interference, nucleotides, and proteins, into or onto the exosomes. RNAi: RNA interference; DEAE: Diethylaminoethyl; PEI: Polyethylenimine.
