APPLICATION OF NON-INVASIVE ULTRASONIC CELL IN PREPARING EXOSOME, EXOSOME, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

摘要

Provided is a preparation method for an exosome. A cell is stimulated by means of non-invasive ultrasound to regulate the microRNA expression abundance in the cell exosome. The method has good universality, is simple in operation, and has a large yield of exosome. A target exosome can be obtained from the method in short time. The obtained exosome can be used for improving the expression of a brain-derived neurotrophic factor, promoting, clearing a harmful protein from the brain, or reducing the oxidative damage of a harmful substance to the brain tissue.
