摘要: 目的:探究钛表面绿原酸(CGA)涂层在高糖环境下的成骨潜能及抗氧化能力。方法:利用[3-(2-氨基乙基氨基)-丙基]三甲氧基硅烷(AEAPTMS)将CGA接枝于钛片表面从而形成生物活性涂层。采用扫描电镜,水接触角仪器对涂层进行表征分析。在高糖环境下用小鼠前成骨细胞系MC3T3-E1评价涂层的细胞增殖、粘附,成骨潜能及活性氧(ROS)生成能力。结果:绿原酸成功覆盖于钛表面,并具有良好的亲水性能;该涂层具有促进细胞的增殖及黏附能力,降低ROS生成且具有一定的成骨潜能。结论:钛表面绿原酸涂层在高糖环境下具有减低ROS生成能力并促进钛表面成骨的作用。

Abstract: Objective:? To explore the osteogenic potential and antioxidant ability of chlorogenic acid (CGA) coating on titanium surface in a high glucose environment. Methods:? A bioactive coating was formed on the titanium surface by grafting CGA using [3 - (2 - amino ethyl amino) - propyl] three oxygen radicals silane (AEAPTMS). The coating was characterized using scanning electron microscopy and a water contact angle instrument. Cell proliferation, adhesion to the coating, osteogenesis potential, and reactive oxygen species (ROS) generation capability were evaluated in MC3T3 E1 cell line under high glucose conditions prior to ossification. Results: The successful grafting of chlorogenic acid onto the titanium surface resulted in a highly hydrophilic coating. This coating effectively enhances cell proliferation and adhesion, while reducing ROS generation and promoting osteogenesis potential. Conclusions:? The chlorogenic acid coating on the titanium surface exhibits a potential to mitigate ROS generation and enhance osteogenesis in a high glucose environment.
