Human umbilical cord mesenchymal stem cell-derived and dermal fibroblast-derived extracellular vesicles protect dermal fibroblasts from ultraviolet radiation-induced photoaging in vitro

In the current study, we proved that MSC-EVs can effectively prevent UVB-induced cell damage via the reduction of intracellular ROS. We believe that this study can provide a new strategy for the prevention of skin photoaging.
