摘要:

背景:干细胞移植后需要对体内的存活、分布、迁徙、增殖及分化进行连续监测,从而评估其疗效和安全性。
目的:分析近10年国内外干细胞标记及MRI示踪研究的文献学特点。
方法:由第一作者用计算机检索中国期刊全文数据库(CNKI),及国际数据库Web of Science数据库,2005年1月至2014年12月关于干细胞磁共振成像示踪研究的文章,在标题和摘要中以“干细胞(stem cell),磁共振成像(magnetic resonance imaging),示踪技术(tracing technique)”为检索词进行检索,并对文献进行深入分析。
结果与结论:目前,干细胞治疗、器官移植、细菌感染、基因表达、新药开发等众多领域已经广泛应用示踪技术。干细胞的示踪技术主要有同位素示踪法、抗原标记法、荧光蛋白标记法、荧光染料标记法、核磁共振对比增强剂标记法、Lac-Z基因标记法、Y染色体标记法。近年来,随着分子影像学的发展,磁共振成像示踪技术在评估干细胞移植的疗效和安全性中应用越来越多。

Abstract:

BACKGROUND: Continuous monitoring is required in the survival, distribution, migration, proliferation and differentiation of transplanted stem cells in vivo thereby to assess its efficacy and safety.
OBJECTIVE: To analyze the characteristics of literature addressing stem cell markers and MRI tracer in the past 10 years.
METHODS: The first author retrieved CNKI and Web of Science by computer for articles about MRI tracing of stem cells published from January 2005 to December 2014, using the keywords of “stem cells, magnetic resonance imaging, tracing technique” that appeared in the title and abstract. Then, the retrieved articles were further analyzed.
RESULTS AND CONCLUSION: Currently, tracing technique has been widely used in stem cell therapy, organ transplantation, bacterial infection, gene expression and new drug development. Stem cell tracing technologies include isotope tracing, antigenic labeling, fluorescence protein labeling, fluorescent dye labeling, nuclear magnetic resonance contrast enhancer labeling, Lac-Z gene labeling, Y chromosome labeling. Recently, with the development of molecular imaging, MRI tracing techniques have been increasingly used to assess the efficacy and safety of stem cell transplantation.
