Immediate treatment for cutaneous injuries is a realistic approach to improve the healing rate and minimise the risk of complications. Multifunctional biomaterials have been proven to be a potential strategy for chronic skin wound management, especially for future advancements in precision medicine. Hence, antioxidant incorporated biomaterials play a vital role in the new era of tissue engineering. A bibliographic investigation was conducted on articles focusing on in vitro, in vivo, and clinical studies that evaluate the effect and the antioxidants mechanism exerted by epigallocatechin gallate (EGCG) in wound healing and its ability to act as reactive oxygen species (ROS) scavengers. Over the years, EGCG has been proven to be a potent antioxidant efficient for wound healing purposes. Therefore, several novel studies were included in this article to shed light on EGCG incorporated biomaterials over five years of research. However, the related papers under this review's scope are limited in number. All the studies showed that biomaterials with scavenging ability have a great potential to combat chronic wounds and assist the wound healing process against oxidative damage. However, the promising concept has faced challenges extending beyond the trial phase, whereby the implementation of these biomaterials, when exposed to an oxidative stress environment, may disrupt cell proliferation and tissue regeneration after transplantation. Therefore, thorough research should be executed to ensure a successful therapy.
对皮肤损伤进行即时治疗是提高愈合率并将并发症风险降至最低的切实可行方法。多功能生物材料已被证明是慢性皮肤伤口管理的一种潜在策略,特别是在精准医学的未来发展方面。因此,含有抗氧化剂的生物材料在组织工程的新时代发挥着至关重要的作用。对聚焦于评估表没食子儿茶素没食子酸酯(EGCG)在伤口愈合中的作用及其作为活性氧(ROS)清除剂的能力的体外、体内和临床研究的文章进行了文献调查。多年来,EGCG已被证明是一种对伤口愈合有效的强效抗氧化剂。因此,本文纳入了几项新颖的研究,以阐明在五年研究中含EGCG的生物材料。然而,本综述范围内的相关论文数量有限。所有研究表明,具有清除能力的生物材料在对抗慢性伤口以及协助伤口愈合过程抵抗氧化损伤方面具有巨大潜力。然而,这一有前景的概念在试验阶段之后面临着挑战,即这些生物材料在暴露于氧化应激环境时,移植后可能会干扰细胞增殖和组织再生。因此,应进行深入研究以确保治疗成功。
