摘要:

文题释义:
半月板:半月板是2个月牙形的纤维软骨,位于胫骨平台内侧和外侧的关节面。其横断面呈三角形,外厚内薄,上面稍呈凹形,以便与股骨髁相吻合,下面为平的,与胫骨平台相接。这样的结构恰好使股骨髁在胫骨平台上形成一较深的凹陷,从而使球形的股骨髁与胫骨平台的稳定性增加。
胞内钙信号系统:几乎人的所有的生理活动都受到Ca2+的调控。Ca2+作为细胞信使的基础是胞浆Ca2+与胞内钙库或胞外Ca2+之间存在浓度梯度。当某种刺激使胞内Ca2+浓度大幅度增加时,就起到传递信号的作用。 Ca2+本身的特性更有利于和靶蛋白结合,从而传递信息。由于要综合多方面功能,Ca2+信号必然是非常灵活,同时又要受到严格的控制。它是借助Ca2+信号的不同的中间环节来实现的,也就是Ca2+可以在不同的时间和空间上以不同幅度来起作用。不同类型的细胞以不同的钙信号组合来完成其特定的生理功能。
摘要
背景:
由于半月板切除后引起的种种不良后果,人们寄希望生物材料学和生物工程学领域能利用组织工程学的方法修复无血供区半月板损伤,种子细胞的选择以及合适的理化刺激是构建组织工程半月板成功与否的关键。
目的:就目前构建组织工程半月板种子细胞及理化因素的研究现状进行综述。
方法:由第一作者检索中国知网及Medline 数据库中有关构建组织工程半月板种子细胞及理化因素的相关文章,中文检索词为“半月板,组织工程,种子细胞,理化因素”,英文检索词为“meniscus,tissue engineering,seed cells,physical and chemical factors”。排除研究目的与课题无关的文章以及重复研究,最后纳入49 篇文献作进一步分析。
结果与结论:构建的组织工程半月板需要建立再现性,必须让种子细胞在理化刺激并复合支架后继续维持其表型和合成能力。目前,已经确定有很多细胞因子可用于促进软骨细胞培养的增殖和分化,但是这些细胞因子的作用机制和调节因素尚不完全清楚,它们在半月板组织工程重建的应用尚处在探索阶段,仍需进一步研究。实现膝关节组织工程半月板,理化刺激可能是目前最需要改进的地方。剪切力通常被对软骨细胞表型认为是有害的,振荡流体已证明,平行板流室的半月板细胞会产生钙信号和糖胺聚糖。使用剪切和其他因素生成的纤维软骨,在未来可能使组织工程半月板受益。精心设计的实验研究:前瞻性、随机性、对照临床试验与长期定量测量结果,是这个领域的研究评价的关键之处。

Abstract:

BACKGROUND: As meniscectomy may result in various adverse reactions, tissue-engineered meniscus is expected to be used for meniscus repair. Seed cell selection and optimal physicochemical stimuli are crucial for the construction of tissue-engineered meniscus.
OBJECTIVE: To overview the seed cells for the tissue-engineered meniscus construction and the research progress of physicochemical factors.
METHODS: The first author retrieved the CNKI and Medline databases using the keywords of “meniscus, tissue engineering, seed cells, physical and chemical factors” in English and Chinese, respectively, to retrieve articles related to the seed cells and physicochemical factors of the tissue-engineered meniscus construction. Irrelative and repetitive articles were excluded, and 49 eligible articles were enrolled for analysis.
RESULTS AND CONCLUSION: The seed cells must maintain their phenotype and synthetic ability after physicochemical stimulation in combination with scaffolds, to achieve the reproducibility of tissue-engineered meniscus. Most of cytokines can be used for promoting the proliferation and differentiation of chondrocytes, but the underlying mechanisms were little known. Their application in the meniscus tissue engineering needs to be studied in depth. Currently it is urgent to improve physicochemical stimuli in order to construct the tissue-engineered meniscus. The shear force does harm to chondrocyte phenotype, and dynamic compression loading has been proved to enhance Ca+ and glycosaminoglycan release. The fibrous cartilage stimulated by shear force and other factors may be helpful for constructing the tissue-engineered meniscus. An elaborated randomized controlled trial and the long-term quantitative analysis are of importance to assess the research results.
