Aloe vera is sometimes used as a folk remedy for minor wounds and burns, but its mechanisms of action in wound healing are unclear.
In this study, the authors evaluate the effects of A vera on wound healing.
In vitro analyses of cell proliferation and migration were conducted on normal human primary skin fibroblasts and keratinocytes in growth media with A vera solution and preservatives at various concentrations. Growth media with preservatives but without A vera solution served as the control.
Aloe vera had significant stimulatory effects on cell proliferation and migration of both fibroblasts and keratinocytes. Surprisingly, A vera also exhibited strong protective effects on preservative-induced keratinocyte death. Keratinocytes in the growth media with both the preservatives and A vera had dramatically higher viability than cells in the control media without A vera.
The results suggest A vera accelerates wound healing by promoting the proliferation and migration of fibroblasts and keratinocytes and by protecting keratinocytes from preservative-induced death.
芦荟有时被用作治疗轻微伤口和烧伤的民间疗法,但其在伤口愈合中的作用机制尚不清楚。
在本研究中,作者评估芦荟对伤口愈合的影响。
在含有不同浓度芦荟溶液和防腐剂的生长培养基中,对正常人原代表皮成纤维细胞和角质形成细胞进行细胞增殖和迁移的体外分析。含有防腐剂但不含芦荟溶液的生长培养基作为对照。
芦荟对成纤维细胞和角质形成细胞的细胞增殖和迁移具有显著的刺激作用。令人惊讶的是,芦荟对防腐剂诱导的角质形成细胞死亡也表现出强大的保护作用。含有防腐剂和芦荟的生长培养基中的角质形成细胞的活力明显高于不含芦荟的对照培养基中的细胞。
结果表明,芦荟通过促进成纤维细胞和角质形成细胞的增殖和迁移以及保护角质形成细胞免受防腐剂诱导的死亡来加速伤口愈合。
