摘要
表没食子儿茶素没食子酸酯(EGCG)是茶叶中多酚类化合物的主要组成部分。近年来许多研究证明,作为一种抗氧化剂,EGCG能够参与调节多种生命过程,在抗炎以及抑制肿瘤生长等方面都具有重要作用。流行病学调查和动物实验都证实,EGCG能够抑制牙周炎及其引起的骨质流失,是牙周治疗的潜在辅助治疗药物。由于兼具抗炎和促成骨功能,EGCG在骨质缺损修复的组织工程材料改性中也具有极大的潜力。本文就EGCG对干细胞的增殖及成骨分化的作用机制进行综述,并总结其作为组织工程材料的优劣,为EGCG在牙周炎辅助治疗药物和骨组织工程材料等方面的研究与应用提供理论依据。
Tea polyphenols are a general term for polyphenols in tea, and epigallocatechin-3-gallate(EGCG) is a major component. As an antioxidant, EGCG can participate in the regulation of various life processes, including anti-inflammatory and anti-tumour activities. Epidemiological investigations and animal experiments have confirmed that EGCG can inhibit periodontitis and subsequent bone loss. Therefore, it might be a potential adjuvant treatment for periodontal treatment. Due to its anti-inflammatory and osteogenic functions, EGCG also has great potential in the modification of tissue engineering materials for bone defect repair. This article reviews the mechanism by which EGCG participates in stem cell proliferation and osteogenic differentiation, and summarises its advantages as a tissue engineering material. This paper provides a theoretical basis for the use of EGCG as periodontitis adjuvant therapy and bone tissue engineering material.
