Abstract
In the last decade, notable developments have occurred regarding the application of membrane vesicles-encompassing extracellular vesicles (EVs, including exosomes, microvesicles, apoptotic bodies, and others), self-organized cellular-membrane-derived vesicles, and isolated cell-bound membrane vesicles, among others-as bioinspired drug delivery systems (DDSs). A collection of 10 papers on such advances was published in the Special Issue of Pharmaceutics entitled "Advances of membrane vesicles in drug delivery systems, 2nd Edition". These papers investigate the Minimum Information for Studies of Extracellular Vesicles (MISEV), in vivo fluorescence imaging and tracking, in vivo specific tissue targeting, and the therapeutic application of membrane vesicles as DDSs in cancers, osteoarthritis, ocular disorders, intestinal disease, and kidney diseases. The present article briefly summarizes these related topics and provides novel insights into the research on membrane vesicles as DDSs.
