摘要：
The present invention relates to stem cell-derived microvesicles with enhanced efficacy, a use thereof, and a method for enhancing efficacy, and more particularly, to a use of stem cell-derived microvesicles with an enhanced expression level of microRNAs for the prevention or treatment of stroke, and a method for promoting the production of microRNAs of stem cell-derived microvesicles and enhancing efficacy, and a method for promoting the production of stem cell-derived microvesicles and microRNAs within the microvesicles and enhancing the efficacy of stem cells and microvesicles thereof by 3-dimensionally culturing or ischemically stimulating stem cells. Since the method according to the present invention has excellent effects capable of promoting the production of stem cell-derived microvesicles and microRNAs in the microvesicles and capable of enhancing the efficacy of stem cells or microvesicles isolated therefrom, it is possible to obtain stem cell-derived microvesicles containing high levels of materials including therapeutic microRNAs efficiently and in large quantities through this, and thus, the microvesicles are expected to be able to be usefully used in related research fields and future clinical settings.
