Abstract
The present disclosure relates to a method of selecting stem cells having the ability to produce extracellular vesicles with high efficiency, the method including the step of measuring the activity of protease-activated receptor (PAR)-mediated signaling pathways, stem cells selected by the method, and a method of screening an inducer for the production of extracellular vesicles. According to the present disclosure, upon treatment of stem cells with thrombin, the production of extracellular vesicles in the stem cells and the levels of proteins in the extracellular vesicles are significantly increased via PAR-mediated signaling pathways, and thus stem cells having the ability to produce extracellular vesicles with high efficiency can be efficiently selected by treating stem cells with thrombin and measuring an activation level of a PAR-mediated signaling pathway, and stem cells selected by this method can be effectively used in related research and clinical fields.
