文题释义:
脱细胞基质
:主要是采用物理和/或化学等方法去除组织/器官的细胞成分,同时保留其组织构架、生物活性成分及生物力学特征而得到的细胞外基质成分。一方面,由于去除了细胞成分,使得这种材料免疫原性较低;另一方面,由于保留了组织器官天然细胞外基质支架的三微结构及可促进细胞黏附、迁移和增殖的生物活性因子等细胞外基质重要成分,同时还保留了血管网络结构,使得脱细胞基质成为一种理想的支架材料的来源。
肾脏细胞外基质:是肾脏细胞在其生长的微环境下合成并分泌到细胞外的,主要由葡萄糖胺聚糖、弹性蛋白、胶原蛋白(主要有Ⅰ型胶原、Ⅳ型胶原等)、纤维连接蛋白、层粘连蛋白等交织而成的网络结构。


背景:研究表明,脱细胞基质材料和合适的种子细胞的有机结合可构建工程化肾脏。
目的:综述脱细胞基质和肾脏组织工程的研究进展。
方法:由第一作者以“脱细胞基质,细胞外基质,组织工程,肾脏,种子细胞”为中文检索词,以“decellularized matrix,extracellular matrix,tissue engineering,kidney, seeded cells”为英文检索词,在CNKI、万方数据库和PubMed数据库检索1999年1月至2016年4月的有关肾脏组织工程的文献。
结果与结论:脱细胞基质材料由于其去除了细胞成分,失去了免疫原性,同时保留了细胞外基质中重要的生物活性成分及组织器官的超微结构,使得其在肾脏组织工程中越来越受到重视,尤其是在最近新兴的全器官脱细胞技术的推动下,使得其在工程化全肾脏的构建中发挥着重要作用。尽管近年来基于脱细胞基质的肾脏组织工程研究发展迅速,并实现了一定功能的工程化肾脏的构建,但在具有完全肾脏功能的工程化肾脏构建中仍面临着一些列的挑战性问题。

Abstract:

BACKGROUND: Previous studies have demonstrated that the well combination of decellularized matrix and appropriate seeded cells could construct a tissue-engineered kidney.
OBJECTIVE: To review advances in kidney tissue engineering and decellularized matrix.
METHODS: The first author retrieved CNKI, Wanfang and PubMed databases for articles addressing kidney tissue engineering published from January 1996 to April 2016. The key words were “decellularized matrix, extracellular matrix, tissue engineering, kidney, seeded cells” in English and Chinese, respectively.
RESULTS AND CONCLUSION: The decellularized matrix loses its immunogenicity due to the removal of cellular
components, while it retains the important bioactive components of the extracellular matrix and the ultrastructure of the tissues and organs, making it more and more important in kidney tissue engineering. The decellularized matrix especially exerts an important role in the tissue-engineered construction of the entire kidney as driven by recently emerging all-organ acellular cell technology. Remarkable advances in kidney tissue engineering and decellularized matrix have been made in recent years, and realized the construction of a certain functional tissue-engineered kidney. However, there are still many challenges on the way to construct a completely functional tissue-engineered kidney.
