The Secretome Derived From Human Umbilical Cord Mesenchymal Stem Cells Improves Skin Photoaging by Enhancing Mitophagy to Inhibit the cGAS‐STING Pathway
Ultraviolet (UV)‐induced skin photoaging is driven by cellular senescence and chronic inflammation. Although the secretome (SCT) derived from human umbilical cord mesenchymal stem cells (hUC‐MSC SCT) exhibits regenerative potential, its role in combating photoaging remains to be elucidated. In this study, we show that...
