摘要:


文题释义:

缓释系统:在药学领域缓释系统是指通过适宜的方法延缓药物在体内的释放、吸收、代谢以及排泄的过程,从而延长药物作用时间或者减轻其毒副作用的给药系统。而在组织工程中,延缓释放的药物一般是生长因子,并且通常和种子细胞和支架构成复合体来构成缓释系统。
血管内皮生长因子(VEFG):是一种高度特异性的促血管内皮细胞生长因子,具有促进血管通透性增加、细胞外基质变性、血管内皮细胞迁移、增殖和血管形成等作用。因为骨骼具有高度的血管化,接受10%-15%的静息心输出量。血管内皮生长因子被发现在骨折愈合血管的长入中起重要作用。

背景:骨软骨的缺损修复是目前骨科医生面对的一大挑战,当前的治疗手段达不到令人满意的效果,组织工程的发展为骨软骨缺损修复带来了新的希望。骨形态发生蛋白2是参与骨骼生长发育和修复的重要因子,具有良好的骨诱导作用,近些年研究发现骨形态发生蛋白2对软骨发育也有影响。
目的:从骨形态发生蛋白2对骨和软骨2个方面的影响,探讨近年来骨形态发生蛋白2在骨软骨缺损修复中的研究进展。并通过总结骨形态发生蛋白2在各类骨缺损修复中的应用情况,为治疗骨软骨的缺损提供新的思路和策略。
方法:在万方数据库和中国知网以“骨形态发生蛋白2,软骨细胞,软骨缺损,骨缺损,间充质干细胞,信号通路”为检索词;在PubMed 数据库以“Bone morphogenetic protein 2,Chondrocytes,Cartilage injury,Bone injury,MSC,Signaling pathways”为检索词,检索2012-01-01/2022-07-01收录的有关骨软骨缺损修复中骨形态发生蛋白2的作用机制及在骨软骨组织工程中的应用研究。
结果与结论:①骨形态发生蛋白2促进间充质干细胞软骨分化,并且能够维持软骨细胞表型来维持软骨的特性。②骨形态发生蛋白2通过调节软骨细胞的糖代谢来控制软骨发育。③骨形态发生蛋白2通过经典Smad 1/5/8信号通路对成骨起作用,但成软骨的机制尚不清楚。④骨形态发生蛋白2目前在组织工程中的研究和应用主要集中在骨缺损修复领域,关于软骨的缺损修复研究较少,如何阻止骨形态发生蛋白2促使软骨细胞向肥大软骨细胞的转化会是未来研究的重点。

Abstract: BACKGROUND: Repair of osteochondral defects is a major challenge that orthopedic surgeons face today, because current treatments fail to achieve satisfactory results. With the development of tissue engineering in recent years, new hope has been brought for the repair of osteochondral defects. Bone morphogenetic protein 2 is an important factor involved in bone growth, development, and repair, with good osteoinductive effects. In recent years, it has been found that bone morphogenetic protein 2 also has an effect on cartilage development.
Objective: To investigate the research progress of bone morphogenetic protein 2 in the repair of osteochondral defects in recent years and to provide new ideas and strategies for the treatment of osteochondral defects by summarizing the application of bone morphogenetic protein 2 in the repair of various types of bone defects.
Methods: WanFang, CNKI, and PubMed databases were searched for literature regarding the mechanism of bone morphogenetic protein 2 in the repair of osteochondral defects and its application in osteochondral tissue engineering published between January 1, 2012 and July 1, 2022. The search terms were “Bone morphogenetic protein 2, Chondrocytes, Cartilage defects, Bone defects, Mesenchymal stem cells, MSC, Signaling pathways” in Chinese and English.

Results and Conclusion: Bone morphogenetic protein 2 promotes chondrogenic differentiation of mesenchymal stem cells and can maintain the chondrocyte phenotype to maintain cartilage properties. Bone morphogenetic protein 2 controls chondrogenesis by regulating chondrocyte glucose metabolism. Bone morphogenetic protein 2 acts on osteogenesis through the classical Smad 1/5/8 signaling pathway, but the mechanism of chondrogenesis is not clear. The current research and application of bone morphogenetic protein 2 in tissue engineering mainly focus on the field of bone defect repair, and less is reported on cartilage defect repair. How to prevent bone morphogenetic protein 2 from promoting the transformation of chondrocytes to hypertrophic chondrocytes will be the focus of future research.

Key words: bone morphogenetic protein 2, signaling pathway, bone defect, cartilage defect, slow release system, bone marrow mesenchymal stem cell, chondrocyte, tissue engineering
