Isolation of Extracellular Vesicles Derived from Mesenchymal Stromal Cells by Ultracentrifugation
Extracellular vesicles (EVs) are a heterogeneous group of membranous vesicles that differ on their biogenesis and release pathways, such as exosomes, microvesicles and apoptotic bodies. They are involved in cell-to-cell communication delivering signal molecules (proteins, nucleic acids, lipids, etc....

| Summary: | Extracellular vesicles (EVs) are a heterogeneous group of membranous vesicles that differ on their biogenesis and release pathways, such as exosomes, microvesicles and apoptotic bodies. They are involved in cell-to-cell communication delivering signal molecules (proteins, nucleic acids, lipids, etc.) that can regulate different physiological processes, as well as the development and progression of several diseases. There are different methods and commercial kits to isolate EVs and depending on the methodology one could obtain EVs with different degrees of efficiency, purity and it can be more or less time-consuming. Then, the choice has to be according to the different advantages and disadvantages, and their use for downstream applications. Here, we describe the EVs isolation method from mesenchymal stromal cells by ultracentrifugation. This EVs isolation can be performed using common media and buffers, and only with the requirement of an analytical ultracentrifuge. Moreover, this method can be used to obtain large quantity of EVs with a good reproducibility for developing in vitro and in vivo experiments and studying their biological actions. |
