research Decorin-mediated dermal papilla cell-derived exosomes regulate hair follicle growth and development through miR-129-2-3p/SMAD3/TGF-β axis
This study found that decorin treatment significantly enhances dermal papilla cell proliferation, promoting hair follicle growth by influencing the SMAD3/TGF-β signaling pathway through exosomal miR-129–2-3p, which may aid in novel strategies for treating hair disorders and enhancing wool production.
