  • Patent number: 10125360
    Abstract: The present invention relates to a method for promoting the generation and secretion of extracellular vesicles from cells by using extracorporeal shockwave. More precisely, the inventors confirmed that the generation and secretion of extracellular vesicles from vascular endothelial cells were promoted by extracorporeal shockwave and further confirmed that siRNA can be transferred into cells without any help of a carrier. The inventors continued to find out that angiogenesis could be inhibited by introducing siRNA to an animal tumor model and succeeded to measure the size and amount of extracellular vesicles secreted by extracorporeal shockwave. Therefore, the present invention can be used in various fields since it can safely promote the generation and secretion of extracellular vesicles from cells.
