Regenerative therapies in the field of facial aesthetics have become a growing field of interest with many recent advancements made over the past decade to meet the growing worldwide demand. While first versions of platelet-derived concentrates were formulated with anticoagulants (PRP), recent modifications to centrifugation speeds and times have permitted the development of a liquid platelet-rich fibrin (fluid-PRF) without use of anticoagulants.
To compare this entirely natural platelet concentrate (fluid-PRF) to formally utilized PRP on skin cell behavior and regeneration.
Dermal skin fibroblast was cultivated with either fluid-PRF or PRP and investigated for their ability to promote/influence cell viability, migration, spreading, proliferation, and mRNA levels of known mediators of dermal biology including PDGF, TGF-beta, and fibronectin.
All platelet concentrates were nontoxic to cells demonstrating high cell survival. Skin fibroblasts migrated over 350% more in fluid-PRF when compared to control and PRP (200% increase). Fluid-PRF also significantly induced greater cell proliferation at 5 days. While both PRP and fluid-PRF induced significantly elevated cell mRNA levels of PDGF, it was observed that TGF-beta, collagen 1, and fibronectin mRNA levels were all significantly highest in the fluid-PRF group. Lastly, fluid-PRF demonstrated a significantly greater ability to induce collagen matrix synthesis when compared to PRP.
The findings from the present study demonstrate greater regenerative potential of fluid-PRF on human skin fibroblasts. Future clinical use of fluid-PRF in the field of facial aesthetics is necessary to further evaluate the potential advantages of anticoagulant removal from platelet concentrates.
在面部美学领域,再生疗法已成为一个日益受到关注的领域,在过去十年中,为满足全球日益增长的需求,取得了许多新的进展。虽然第一代血小板浓缩物是用抗凝剂(PRP)配制的,但最近对离心速度和时间的修改允许开发一种无需使用抗凝剂的液体富血小板纤维蛋白(fluid-PRF)。
将这种完全天然的血小板浓缩物(fluid-PRF)与正式使用的 PRP 进行比较,以观察其对皮肤细胞行为和再生的影响。
将真皮皮肤成纤维细胞与 fluid-PRF 或 PRP 培养,并研究其促进/影响细胞活力、迁移、扩散、增殖以及已知真皮生物学介质的 mRNA 水平的能力,包括 PDGF、TGF-β 和纤维连接蛋白。
所有血小板浓缩物对细胞均无毒性,细胞存活率高。与对照和 PRP 相比,fluid-PRF 中皮肤成纤维细胞迁移增加了 350%以上(增加了 200%)。fluid-PRF 还显著诱导了 5 天的更高细胞增殖。虽然 PRP 和 fluid-PRF 都显著提高了 PDGF 的细胞 mRNA 水平,但观察到 TGF-β、胶原蛋白 1 和纤维连接蛋白的 mRNA 水平在 fluid-PRF 组中均最高。最后,fluid-PRF 显示出比 PRP 更强的诱导胶原基质合成的能力。
本研究的结果表明,fluid-PRF 对人皮肤成纤维细胞具有更强的再生潜力。未来在面部美学领域临床应用 fluid-PRF,以进一步评估从血小板浓缩物中去除抗凝剂的潜在优势。
