MAPK/AP-1 Signaling Pathway Is Involved in the Protection Mechanism of Bone Marrow Mesenchymal Stem Cells-Derived Exosomes against Ultraviolet-Induced Photoaging in Human Dermal Fibroblasts

Abstract

BMSCs-exo protected HDFs against UVB-induced inhibition of cell viability and the activation of cell oxidative stress and inflammation, which might be related to the inhibition of the MAPK/AP-1 signaling pathway.
