Schematic representation of therapeutic effects mediated by MSC-EVs. MSC-EVs can support the recovery of injured organs, and this supportive effect is dependent on EV content molecules. In this article, content molecule-dependent therapeutic effects are classified into three categories: protein-mediated effects, RNA-mediated effects, and undefined molecule-mediated effects (summarized in Tables 1, 2 and 3, respectively).
