摘要
Platelet rich plasma (PRP) has been accepted as a potential therapy for treating androgenetic alopecia (AGA).To fully clarify the underling molecular mechanisms of PRP action on hair growth and promote its clinical applications.In this study, we used mice models and protein biochip to explore the specific mechanisms of PRP regulating hair growth. Then, we performed a randomized, placebo-controlled, double-blind, half-head study of 52 AGA patients to verify the therapeutic efficacy of PRP in Chinese AGA patients.The results confirmed that PRP treatment boosted hair regrowth, accelerated hair cycling, and the effect sustained for more than one hair cycle in mice. Protein biochip evaluation confirmed remarkably upregulated β-Catenin, PDGF, and AKT signaling and repressed p53 signaling in PRP injection group. Clinically, mean hair count, density, diameter, and anagen hair ratio in PRP group showed a significant improvement at 6 month comparing to control side.Overall, we elucidated the specific molecular mechanism of PRP action on hair growth and proved the therapeutic efficacy and safety of PRP in Chinese AGA patients.
