research Human hair follicle mesenchymal stem cell-derived exosome attenuates UVB-induced photoaging via the miR-125b-5p/TGF-β1/Smad axis
This study demonstrated that exosomes from human hair follicle mesenchymal stem cells can enhance collagen production, promote cell proliferation and migration in human dermal fibroblasts, and reverse signs of UV-induced skin aging in mice, potentially via a miR-125b-5p/TGF-β1/Smad signaling pathway.
