A preview of a science news article describing preclinical research on a stem-cell secretome therapy to counteract UV-driven skin aging by restoring damaged-mitochondria clearance.
Key Takeaways
- Topical hUC-MSC secretome prevented UV-induced epidermal thickening and preserved skin collagen in mice.
- Secretome treatment restored mitophagy markers PINK1, Parkin, and LC3B-II to levels like unexposed controls.
- Secretome reduced cGAS-STING activation and downstream cytokines, and its benefits required functional mitophagy.
