文题释义:
组织工程心脏:是将通过体外扩增的细胞种植于生物相容性良好的支架材料上,细胞能够牢固黏附、生长增殖和定向诱导分化,使其具有心脏组织的细胞组成和基本功能,实现能够在体外生产出可以代替正常心脏的功能性心脏组织的最终目标。
去细胞支架材料:去细胞是指用去污剂将组织或器官中的细胞去除,获得一个保留完整细胞外基质的组织或器官支架,并维持其原有的三维空间结构、生化组成和生物活性。要得到良好的去细胞心脏支架,选择一个能够将细胞去除完全,且维持原有组织或器官完整的支架系统和机械强度的去污剂至关重要。
摘要
背景:
由于供体心脏严重短缺并受制于伦理道德,很多需要心脏移植的患者最终因缺乏供体心脏而死亡。理论上组织工程心脏是解决供体心脏不足的重要手段。
目的:回顾分析组织工程心脏构建用的支架材料、种子细胞及细胞接种培养方法,为后期组织工程心脏的构建做参考。
方法:由作者检索2004年至2016年PubMed数据库及SCI(web of science)数据库关于组织工程心脏构建方法研究的文献,共检索文献2 921篇,按照纳入和排除标准进行筛选,共纳入53篇。
结果与结论:器官的体外培养及组织工程心脏功能是组织工程心脏构建的难点。组织工程心脏体外培养需要提供心肌细胞增殖需要的营养、气体、温度及相应的电刺激。心肌细胞的诱导、支架材料的获取及体外培养系统的建立是组织工程心脏构建过程中不可缺少的条件。优化支架材料的脱细胞流程,整合理想的种子细胞并提高其在支架内的黏附、增殖和分化能力,通过基因调控改善组织工程心脏的电生理特性,长期的安全性分析等,每一项研究目标都任重而道远。

Abstract:

BACKGROUND: Insufficiency of donor heart and ethics are the major obstacles to heart transplantation. Theoretically, a tissue-engineered heart is an important means to solve the donor heart insufficiency.
OBJECTIVE: To review the scaffold materials, seed cells and cell incubation methods in the construction of tissue-engineered heart, thus providing references for the future study on the tissue-engineered heart. 
METHODS: A retrieval of PubMed and Web of Science databases was performed for the articles addressing the construction of tissue-engineered heart from 2004 to 2016. Totally 2 921 articles were searched, and finally 53 eligible articles were included in accordance with the inclusion and exclusion criteria.
RESULTS AND CONCLUSION: In vitro organ culture and the function of tissue-engineered heart are the difficulties in the construction of tissue-engineered heart. In vitro construction of tissue-engineered heart requires the supply of nutrients, gases, temperature and corresponding electrical stimulation. Myocardial cells, scaffold materials and organ culture system are indispensable for the tissue-engineered heart construction. Therefore, it is highly important to optimize the decellular process, select an ideal seed cell and improve its adhesion, proliferation and differentiation, improve the electrophysiological properties of the tissue-engineered heart by gene regulation, and confirm the long-term safety of the tissue-engineered heart.
