Articular cartilage damage and wear can result in cartilage degeneration, ultimately culminating in osteoarthritis. Current surgical interventions offer limited capacity for cartilage tissue regeneration and offer only temporary alleviation of symptoms. Tissue engineering strategies are increasingly recognized as promising modalities for cartilage restoration. Currently, various biological scaffolds utilizing tissue engineering materials are extensively employed in both fundamental and clinical investigations of cartilage repair. In order to optimize the cartilage repair ability of tissue engineering scaffolds, researchers not only optimize the structure and properties of scaffolds from the perspective of materials science and manufacturing technology to enhance their histocompatibility, but also adopt strategies such as loading cells, cytokines, and drugs to promote cartilage formation. This review provides an overview of contemporary tissue engineering strategies employed in cartilage repair, as well as a synthesis of existing preclinical and clinical research. Furthermore, the obstacles faced in the translation of tissue engineering strategies to clinical practice are discussed, offering valuable guidance for researchers seeking to address these challenges.
关节软骨损伤和磨损可导致软骨退化,最终导致骨关节炎。目前的手术干预方法对软骨组织再生的能力有限,只能暂时缓解症状。组织工程策略越来越被认为是软骨修复的有前途的方法。目前,各种利用组织工程材料的生物支架在软骨修复的基础和临床研究中得到了广泛应用。为了优化组织工程支架的软骨修复能力,研究人员不仅从材料科学和制造技术的角度优化支架的结构和性能,以提高其组织相容性,还采用加载细胞、细胞因子和药物等策略来促进软骨形成。本文综述了用于软骨修复的当代组织工程策略,并对现有临床前和临床研究进行了综合分析。此外,还讨论了将组织工程策略转化为临床实践所面临的障碍,为研究人员解决这些挑战提供了有价值的指导。
