摘要: 细胞谱系示踪技术是研究干细胞特性的重要工具,基于Cre/Loxp重组酶系统的谱系示踪技术是示踪方法的一大突破,组成性重组酶系统实现了报告基因的组织特异性,诱导性重组酶系统在此基础上实现了报告基因表达时间的可控性。研究成骨改建机制涉及成骨细胞系命运,对骨改建研究、组织工程学应用是有重要意义。本文综述了基于Cre/Loxp重组酶系统的谱系示踪技术在研究成骨系细胞分化、来源、转归及其在发育和修复中的功能等方面的应用,并探讨其适用范围、优势和不足。

Abstract: [Summary] Cell lineage tracing technology is an important tool to study the characteristics of stem cells, among which, the one based on Cre/Loxp recombinase system is a great breakthrough. General recombinase system realizes the tissue specificity of reporter gene, based on which, inducible recombinase system makes controlling the expression time of reporter gene possible. The study of the mechanism of osteogenic remodeling is related to the fate of osteoblast lines, which is of great significance to the study of bone remodeling and the application of tissue engineering. This paper reviewed the application of lineage tracing technique based on Cre/Loxp recombinase system in the study of the origin, differentiation, lineage and hierarchy of osteoblast lines and their function in development and repair, and discussed its scope of application, advantages and disadvantages.

Key words: Lineage tracing, Osteogenic remodeling, Cre/Loxp recombinase system
