诱导多能干细胞(iPS)为再生医学应用提供了非凡的前景,并为疾病建模,药物筛选和药物毒理学提供了新的机会。iPS细胞技术仍处于起步阶段。在这篇综述文章中,我们提出了一个全面的调查重编程的方法,重点是用于从体细胞产生iPS细胞的基因递送系统,分类基因递送载体,并讨论其优点和局限性的体细胞重编程。我们包括2006年至今发表的相关文献。虽然iPS细胞技术已经通过使用各种基因递送载体得到了改进,但它仍然存在重编程效率低或基因组修饰步骤太多的问题。仍然需要大量的工作来改进当前的载体或探索新的载体,以有效地将人类体细胞重编程为iPS细胞,具有或不具有最小的基因组修饰步骤。具有高重编程效率的单一非整合重编程载体系统对于产生临床上可翻译的人iPS细胞可能是必不可少的。
Induced pluripotent stem (iPS) cells offer extraordinary promise for regenerative medicine applications, and provide new opportunities for use in disease modeling, drug screening and drug toxicology. iPS cell technology is still in its infancy. In this review article, we present a comprehensive survey of reprogramming approaches focusing on gene-delivery systems used for generation of iPS cells from somatic cells, categorize gene-delivery vectors, and discuss their advantages and limitations for somatic cell reprogramming. We include pertinent literature published between 2006 and the present. Although iPS cell technology has been improved via the use of various gene-delivery vectors, it still suffers from either low reprogramming efficiency or too many genomic modification steps. Extensive work is still required to improve current vectors or explore new vectors for effectively reprogramming human somatic cells into iPS cells, with or without minimal genomic modification steps. A single non-integrating reprogramming vector system with high reprogramming efficiency is probably essential for generation of clinically translatable human iPS cells.
