HucMSC Exosome-Delivered 14-3-3ζ Alleviates Ultraviolet Radiation-Induced Photodamage via SIRT1 Pathway Modulation

To investigate the functions of exosomes derived from human umbilical cord MSC (hucMSC-ex) in a rat model of acute skin photodamage, immunofluorescence and immunohistochemical staining, quantitative real-time-polymerase chain reaction, western blot, and gene silencing assays were performed.
