Platelet-Rich Plasma-Derived Exosomes Stimulate Hair Follicle Growth Through Activation of the Wnt/β-Catenin Signaling Pathway

The study demonstrates that platelet-rich plasma-derived exosomes (PRP-Exos) significantly promote hair follicle growth by activating the Wnt/β-Catenin signaling pathway. PRP-Exos enhance the proliferation and migration of dermal papilla cells (DPCs) and reduce apoptosis in hair follicles, leading to notable hair regrowth in C57BL/6 mice, comparable to minoxidil but without adverse effects. The findings suggest that PRP-Exos could be a promising, non-invasive treatment for androgenetic alopecia, offering a novel approach to hair loss treatment with low immunogenicity and high biocompatibility. Future research will focus on the clinical safety and efficacy of PRP-Exos.
