Method for constructing functional exosomes capable of efficiently loading specific miRNA

Abstract

The invention discloses a method for constructing functional exosomes capable of efficiently loading specific miRNA. In order to enable the exosome to carry miRNA with specific regulation function more efficiently so as to play a role in targeted regulation more accurately and efficiently, MS2 phage capsid protein is utilized to edit and construct a capture element of a specific miRNA molecule, and placenta mesenchymal stem cells are reprogrammed to enable the secreted exosome to efficiently load a target miRNA molecule, so that the target miRNA molecule is delivered to tissue cells to play a role in effective regulation, and therefore a new strategy is provided for realizing specific precise treatment in the future.
