| Outline of Final Research Achievements |
Extracellular Vesicles (EVs) such as exosome are nanovesicles secreated by various types of cells. EVs are known to include proteins (cytosolic and membrane proteins) and RNAs. EVs are considered as proteins and RNAs (mRNA and miRNA) cargo for cell-cell communication, and there is an exponentially growing interest in medical application of exosomes. We propose new strategy for application of exosomes to DDS by modifying the surface of EVs with functional polymers. We developed the modification of EVs surfaces by amphiphilic polysaccharide nanogels and cationic nanogels. Moreover, interactions of EVs and cationic nanogels modified EVs to cells were investigated. The cell did not uptake well the exosomes alone. The cationic nanogels modified EVs, however, were significantly interacted with cells. Functionalization of EVs with nanogels is promising for wide application of exosomes.
