Abstract

Cartilage plays an important role in supporting soft tissues, reducing joint friction, and distributing pressure. However, its self-repair capacity is limited due to the lack of blood vessels, nerves, and lymphatic systems. Tissue engineering offers a potential solution to promote cartilage regeneration by combining scaffolds, seed cells, and growth factors. Among these, growth factors play a critical role in regulating cell proliferation, differentiation, and extracellular matrix remodeling. However, their instability, susceptibility to degradation and potential side effects limit their effectiveness. This article reviews the main growth factors used in cartilage tissue engineering and their delivery strategies, including affinity-based delivery, carrier-assisted delivery, stimuli-responsive delivery, spatial structure-based delivery, and cell system-based delivery. Each method shows unique advantages in enhancing the delivery efficiency and specificity of growth factors but also faces challenges such as cost, biocompatibility, and safety. Future research needs to further optimize these strategies to achieve more efficient, safe, and economical delivery of growth factors, thereby advancing the clinical application of cartilage tissue engineering.

软骨组织工程中生长因子的输送策略。
软骨在支撑软组织、减少关节摩擦和分散压力方面发挥着重要作用。然而,由于缺乏血管、神经和淋巴系统,软骨的自我修复能力有限。组织工程通过结合支架、种子细胞和生长因子,为促进软骨再生提供了一种潜在的解决方案。其中,生长因子在调节细胞增殖、分化和细胞外基质重塑方面起着至关重要的作用。然而,生长因子的不稳定性、易降解性和潜在的副作用限制了其有效性。本文回顾了软骨组织工程中使用的主要生长因子及其递送策略,包括亲和性递送、载体辅助递送、刺激响应递送、空间结构递送和细胞系统递送。每种方法在提高生长因子的输送效率和特异性方面都显示出独特的优势,但也面临着成本、生物相容性和安全性等挑战。未来的研究需要进一步优化这些策略,以实现更高效、安全和经济的生长因子输送,从而推动软骨组织工程的临床应用。
