Abstract

RNA interference (RNAi) has tremendous potential for specific silencing of disease-causing genes. Its clinical usage however critically depends on the development of carrier systems that can transport the RNAimediating small interfering RNA (siRNA) molecules to the cytosol of target cells. Recent reports have suggested that extracellular vesicles (EVs) form a natural transport system through which biomolecules, including RNA, is exchanged between cells. Therefore, EVs are increasingly being considered as potential therapeutic siRNA delivery systems. In this chapter we describe a method for preparing siRNA-loaded EVs, including a robust, scalable method to isolate them from cell culture supernatants.
