文题释义:
肌腱干细胞:
从人和鼠的肌腱组织中成功分离提取出这种细胞,并发现在体外培养时这种细胞表现出克隆形成能力、自我更新及多向分化潜能等细胞的普遍特性,而且植入体内后可生成肌腱样组织,于是将这种细胞群定义为肌腱干细胞。
牵张应力:牵张应力的加载装置主要是通过各种方法对培养基膜的牵拉,使黏附于基膜上的细胞被动伸展,应用此力学装置,能较好的模拟体内组织受牵拉时的力学环境,可以给予细胞静止性或周期性,单向或双轴的牵拉,牵张应力大小及时间频率可以量化,加载刺激时或刺激前后均可用显微镜观察细胞情况。

摘要
背景:
随着组织工程技术的发展和再生肌腱研究的深入,将解决传统肌腱移植所引起的诸多问题。
目的:依据肌腱自身性质、干细胞的优缺点、机械力学系统的特点以及相应的力学系统对种子细胞的影响进行评价与展望。
方法:检索中国生物医学文献数据库(CBM)、中国知识资源总库(CNKI)系列数据库、中文科技期刊数据库、PubMed 数据库 2005年1月至2015年12月收录的肌腱组织工程相关综述和论文报告,检索词为组织工程(tissue engineering),肌腱(tendon),肌腱干细胞(tendon stem cell),力学刺激(mechanical stimulation),种子细胞(seeding cells),最终纳入63篇文献进行分析。
结果与结论:①各种干细胞及相应的力学系统在组织工程的应用中各有优势和不足,研究者可根据研究需要加以选择;②肌腱干细胞在再生肌腱领域里应用有着广阔的前景,通过合适、精确、温和的机械力学刺激将肌腱干细胞培养成为满足需要的肌腱组织,将为医生和患者改善肌腱损伤后临床愈合效果提供另一种选择。

Abstract:

BACKGROUND: With the development of tissue engineering technology and the deep research of tendon regeneration, many problems caused by traditional tendon transplantation will be solved.
OBJECTIVE: To evaluate and prospect the effects of corresponding mechanical systems on seeding cells based on the characters of tendon, stem cells as well as mechanical systems.
METHODS: CBM, CNKI, CqVip and PubMed databases were retrieved for reviews and articles related to tissue-engineered tendon published from January in 2005 to December in 2015. The keywords were “tissue engineering, tendon, tendon stem cell, mechanical stimulation and seeding cells” in Chinese and English, respectively. Finally a total of 63 articles were selected for overview.
RESULTS AND CONCLUSION: As all kinds of stem cells and the corresponding mechanical systems exhibit advantages and disadvantages when applied for tissue engineering, it is advisable to make appropriate choices according to the research needs. Tendon stem cells show a broad application prospect in tendon regeneration, which will grow into required tendon tissues through appropriate, accurate and gentle mechanical stimulations, thereby providing another alternative to improve the tendon healing.
