research Mesenchymal stem cell-derived exosomes promote scalp rejuvenation through type XVII collagen regulation via the miR-21-5p/DKK2/Wnt pathway
This study found that exosomes from human umbilical cord mesenchymal stem cells reduced hair follicle aging and promoted hair regeneration in models by upregulating COL17A1 through the miR-21-5p/DKK2/Wnt/β-catenin axis, outperforming existing treatments like minoxidil.
