The fabrication of functional tissue or organs substitutes has always been the pursuit of goals in the field of tissue engineering. But even biocompatible tissue-engineered scaffolds still suffer from immune rejection, subsequent long-term oxidative stress and inflammation, which can delay normal tissue repair and regeneration. As a well-known natural antioxidant, polyphenols have been widely used in tissue engineering in recent years. The introduced polyphenols not only reduce the damage of oxidative stress to normal tissues, but show specific affinity to functional molecules, such as receptors, enzyme, transcription and transduction factors, etc. Therefore, polyphenols can promote the recovery process of damaged tissues by both regulating tissue microenvironment and participating in cell events, which embody specifically in antioxidant, anti-inflammatory, antibacterial and growth-promoting properties. In addition, based on its hydrophilic and hydrophobic moieties, polyphenols have been widely used to improve the mechanical properties and anti-degradation properties of tissue engineering scaffolds. In this review, the research advances of tissue engineering scaffolds containing polyphenols is discussed systematically from the aspects of action mechanism, introduction method and regulation effect of polyphenols, in order to provide references for the rational design of polyphenol-related functional scaffolds.
功能性组织或器官替代物的制造一直是组织工程领域所追求的目标。但即使是具有生物相容性的组织工程支架仍会遭受免疫排斥、随后的长期氧化应激和炎症,这会延迟正常组织的修复和再生。作为一种著名的天然抗氧化剂,多酚近年来已广泛应用于组织工程。引入的多酚不仅能减少氧化应激对正常组织的损伤,还对功能分子如受体、酶、转录和转导因子等表现出特异性亲和力。因此,多酚可通过调节组织微环境和参与细胞活动来促进受损组织的恢复过程,这具体体现在抗氧化、抗炎、抗菌和促生长特性上。此外,基于其亲水和疏水部分,多酚已被广泛用于改善组织工程支架的机械性能和抗降解性能。在本综述中,从多酚的作用机制、引入方法和调节效果等方面系统地讨论了含多酚组织工程支架的研究进展,以便为多酚相关功能支架的合理设计提供参考。
