摘要:

背景:诱导性多能干细胞自发现以来一直是再生医学的研究热点,但人们过多地关注了它的运用性却忽略了安全性。

 

目的:通过综述目前诱导性多能干细胞在动物移植研究中的表现,分析诱导性多能干细胞的安全性问题及可能原因,为今后的诱导性多能干细胞研究及临床运用提供参考。

 

方法:以英文检索词为“induced pluripotent stem cells,safety,immune,immunogenicity,tumorigenicity,cancer,epigenomic,transplantation,Generation,Reprogramming,genomic,mutation”由第一作者检索2006至2014年PubMed数据库,查阅近年来与诱导性多能干细胞安全性相关的文献,进一步从Cell Press数据库和Nature数据库中获得文献全文阅读,最终保留发表时间较近的28篇文献。

 

结果与结论:诱导性多能干细胞的安全性问题正引起越来越多人的重视,免疫原性、潜在的致瘤性与表观遗传学变异问题是其临床应用的主要隐患。诱导性多能干细胞的安全性问题主要来自于重编程过程,“插入式基因操作”比非插入式操作具有更大的致瘤风险。体细胞重编程后不同程度的发生了表观遗传学变异,这些变异多与被重编程细胞的“遗传记忆”有关。

Abstract:

BACKGROUND: Induced pluripotent stem cells have been a hotspot in regenerative medicine research since it was discovered. The clinical application of induced pluripotent stem cells is excessively focused on, but the safety issue is almost ignored.

OBJECTIVE: By summarizing the application of induced pluripotent stem cells in animal experiments to analyze the safety problems of induced pluripotent stem cells and their possible reasons in order to lay a foundation for further study and clinical application of induced pluripotent stem cells.
METHODS: PubMed database was retrieved by the first author for articles related to the safety of induced pluripotent stem cells published from 2006 to 2014 using the keywords of “induced pluripotent stem cells, safety, immune, immunogenicity, tumorigenicity, cancer, epigenomic, transplantation, generation, reprogramming,genomic, mutation” in English. Related full texts were got from Cell Press and Nature Databases. Finally, 28 articles were chosen in result analysis.
RESULTS AND CONCLUSION: Safety problems of induced pluripotent stem cells are attracting more and more attentions. Immunogenicity, potential tumorigenicity and epigenetic variation are major risks for the clinical applications of induced pluripotent stem cells. Safety issues of induced pluripotent stem cells mainly come from the reprogramming process. The “integrating genetic manipulation” may lead to a greater risk of tumorigenicity than non-integrating operations. Epigenetic variations emerge in the reprogramming, which are mostly relative to “epigenetic memory” of reprogrammed cells.
