摘要:

背景:目前临床上应用的心脏生物瓣和机械瓣都存在一些缺陷和不足,而组织工程心脏瓣膜有可能避免这些问题的出现,成为瓣膜替代物的理想选择。
目的:探讨构建组织工程心脏瓣膜的实验研究进展。
方法:应用数据库检索的方法分析关于组织工程心脏瓣膜的实验研究文献,组织工程心脏瓣膜的三大要素为种子细胞、支架材料和细胞种植。
结果与结论:心脏瓣膜修复和置换是目前治疗心脏瓣膜性疾病的主要外科手段。目前,主要用于构建组织工程心脏瓣膜的种子细胞有血管内皮细胞、内皮祖细胞以及骨髓间充质干细胞等。经脱细胞处理的支架具有良好的生物力学性能和组织相容性,细胞种植后支架表面会形成一层连续的细胞层,其构建的组织工程心脏瓣膜是可行的。组织工程心脏瓣膜有着良好的应用前景,但目前还有很多问题需要解决,还处于研究的初级阶段。

Abstract:

BACKGROUND: Current cardiac bioprostheses and mechanical valves are shown to have some flaws and shortcomings, and tissue-engineered heart valves which can avoid these problems are becoming an ideal choice for valve replacement.
OBJECTIVE: To explore the experimental progress in the construction of tissue-engineered heart valves.
METHODS: Experimental studies related to tissue-engineered heart valves were retrieved in databases. Three main elements for tissue-engineered heart valves are seed cells, scaffold materials, and cell seeding.
RESULTS AND CONCLUSION: Cardiac valve repair and replacement is the primarily surgical treatment for valvular heart disease. At present, seed cells mainly for construction of tissue-engineered heart valves include vascular endothelial cells, endothelial progenitor cells and bone marrow mesenchymal stem cells. The acellular scaffold has good biomechanical properties and histocompatibility. After cell seeding, a continuous cell layer will form on the scaffold surface, which makes it possible to construct tissue-engineered heart valves. Tissue-engineered heart valve has a good prospect, but it is still in the early stage of research and there are still many problems that need to be solved.
