Otosolog Plazma Zengin Trombosit: Saç Büyümesini Teşvik Etmek İçin Potansiyel Bir Terapötik Araç

Özet (abstract)

BACKGROUND: Recently, autologous platelet-rich plasma (PRP) has attracted attention in various medical fields, including plastic and orthopedic surgery and dermatology, for its ability to promote wound healing. PRP has been tested during facelift and hair transplantation to reduce swelling and pain and to increase hair density. OBJECTIVE: To investigate the effects of PRP on hair growth using in vivo and in vitro models. METHODS: PRP was prepared using the double-spin method and applied to dermal papilla (DP) cells. The proliferative effect of activated PRP on DP cells was measured. To understand the mechanisms of activated PRP on hair growth, we evaluated signaling pathways. In an in vivo study, mice received subcutaneous injections of activated PRP, and their results were compared with control mice. RESULTS: Activated PRP increased the proliferation of DP cells and stimulated extracellular signal-regulated kinase (ERK) and Akt signaling. Fibroblast growth factor 7 (FGF-7) and beta-catenin, which are potent stimuli for hair growth, were upregulated in DP cells. The injection of mice with activated PRP induced faster telogen-to-anagen transition than was seen on control mice. CONCLUSIONS: Although few studies tested the effects of activated PRP on hair growth, this research provides support for possible clinical application of autologous PRP and its secretory factors for promotion of hair growth.
