Aim. The purpose of this study was to determine the in vitro response of cells critical to the wound healing process in culture media supplemented with a lyophilized preparation rich in growth factors (PRGF) and Manuka honey. Materials and Methods. This study utilized cell culture media supplemented with PRGF, as well as whole Manuka honey and the medical-grade Medihoney (MH), a Manuka honey product. The response of human fibroblasts (hDF), macrophages, and endothelial cells (hPMEC) was evaluated, with respect to cell proliferation, chemotaxis, collagen matrix production, and angiogenic potential, when subjected to culture with media containing PRGF, MH, Manuka honey, and a combination of PRGF and MH. Results. All three cell types demonstrated increases in cellular activity in the presence of PRGF, with further increases in activity seen in the presence of PRGF+MH. hDFs proved to be the most positively responsive cells, as they experienced enhanced proliferation, collagen matrix production, and migration into an in vitro wound healing model with the PRGF+MH-supplemented media. Conclusion. This preliminary in vitro study is the first to evaluate the combination of PRGF and Manuka honey, two products with the potential to increase regeneration individually, as a combined product to enhance dermal regeneration.
目的。本研究的目的是确定在补充了富含生长因子的冻干制剂(PRGF)和麦卢卡蜂蜜的培养基中,对伤口愈合过程至关重要的细胞的体外反应。材料与方法。本研究使用了补充有PRGF的细胞培养基,以及全麦卢卡蜂蜜和一种麦卢卡蜂蜜产品——医用级Medihoney(MH)。评估了人成纤维细胞(hDF)、巨噬细胞和内皮细胞(hPMEC)在含有PRGF、MH、麦卢卡蜂蜜以及PRGF与MH组合的培养基中培养时,在细胞增殖、趋化性、胶原蛋白基质产生和血管生成潜力方面的反应。结果。在PRGF存在的情况下,所有三种细胞类型的细胞活性均有所增加,在PRGF+MH存在时活性进一步增加。hDF被证明是反应最积极的细胞,因为在补充了PRGF+MH的培养基中,它们在体外伤口愈合模型中经历了增殖增强、胶原蛋白基质产生增加以及迁移增加。结论。这项初步的体外研究首次评估了PRGF和麦卢卡蜂蜜这两种各自具有促进再生潜力的产品作为联合产品增强皮肤再生的情况。
