Stemgent mRNA体细胞重编程系统

产品特点

1.快速 Fast

Stemgent® MicroRNA-Enhanced mRNA Reprogramming System只需2周即可将靶细胞重编程为iPS细胞，与仙台病毒（Sendai Virus）、非整合型DNA载体（Episomal DNA Vectors）等传统iPS重编程方法相比，缩短实验周期超过50%以上（Figure. 1）。

Figure 1. Stemgent® mRNA重编程系统、仙台病毒依赖的重编程系统以及游离型DNA载体依赖的重编程系统重编程时程比较。

简便 Easy

与病毒、DNA载体依赖的iPS重编程手段不同，使用Stemgent® MicroRNA-Enhanced mRNA Reprogramming System对靶细胞进行重编程，生成的iPS细胞无需进行复杂耗时的下游筛选程序，只需简简单单6个步骤，即可轻松构建iPS细胞系。

	Description	Day
Step 1	Material Preparation	Prior to starting
Step 2	Plate Cells	0
Step 3	Transfect Cells	1 to 12
Step 4	Identify Cells	13-14
Step 5	Pick and Passage iPS Cell Colonies	15-16
Step 6	Maintain iPS Cell Cultures	16+

注：因所用细胞类型及实验条件不同，上述时间轴可能略有不同，仅供参考。

高效 Efficient

病毒、DNA载体等依赖的iPS重编程技术，其重编程效率介于0.00001%到1%之间不等，而Stemgent® MicroRNA-Enhanced mRNA Reprogramming System的重编程效率远远大于1%，极大地提高了iPS克隆的产出率。

表1. 不同类型iPS重编程手段效率比较

Reprogramming Method	Efficiency	Integrating	Screening
RNA	>1%	No	No
仙台病毒（Sendai virus）	0.01-1%	No	Yes
DNA载体（Episomal/Minicircle）	0.00%	Possible	Yes
慢病毒（Lentivirus）	0.001-0.01%	Yes	Yes
腺病毒（Adenovirus）	0.0001-0.001%	Possible	Yes
Protein	0.00%	No	No

安全 Safe

某些iPS研究领域，例如iPS临床研究、治疗应用等，对iPS细胞的安全性提出了极高的要求。使用Stemgent® MicroRNA-Enhanced mRNA Reprogramming System重编程靶细胞，无需担心构建的iPS细胞系可能含有病毒载体残留，亦无需担心无关的基因整合进宿主基因组，是目前适用于临床研究及治疗的最理想选择。

而以仙台病毒（Sendai Virus）为载体的iPS重编程手段，其病毒基因组虽然不会整合进宿主染色体，仙台病毒本身也不具备复制能力，但是为了构建真正意义上的virus-free的iPS细胞系，通常需要经过一个10-20代、耗时费力的筛选过程，以确保最终得到的iPS细胞系无病毒载体残留。以慢病毒（Lentivirus）体的iPS重编程手段，病毒基因组能够永久整合进宿主基因组，会给后续的iPS细胞分析带来干扰。
