小鼠胚胎干细胞(ESC)可以通过电穿孔、脂质体试剂和病毒转导方法转染。阳离子聚合物聚乙烯亚胺 (PEI) 已被证明可以转染多种分化的哺乳动物细胞类型,包括小鼠 ESC,但现有方法需要使用大多数实验室不易获得的额外设备。在这里,我们描述了无需特殊设备即可以低细胞毒性高效转染小鼠 ESC 的条件。我们的目标是设计一种 PEI 介导的小鼠 ESC 转染方案,其易用性与商业转染试剂相当。在这些研究中,我们使用荧光显微镜、流式细胞术、细胞活力测定和蛋白质印迹将 PEI 转染效率和细胞毒性与著名的脂质体转染试剂 Lipofectamine2000™ (LF2K) 进行比较。我们提供的证据表明,PEI 转染小鼠 ESC 的效果优于 LF2K。本报告详细介绍了我们用 PEI 高效转染小鼠 ESC 的优化方案。
Mouse embryonic stem cells (ESCs) can be transfected by electroporation, liposomal reagents, and viral transduction methods. The cationic polymer polyethylenimine (PEI) has been shown to transfect a variety of differentiated mammalian cell types, including mouse ESCs, but existing methods require the use of additional equipment that is not readily accessible to most labs. Here we describe conditions that permit for the efficient transfection of mouse ESCs with low cytotoxicity and without the need for specialized equipment. Our goal was to devise a protocol for the PEI-mediated transfection of mouse ESCs that was comparable in ease to commercial transfection reagents. For these studies, we compared PEI transfection efficiency and cytotoxicity to a well-known liposomal transfection reagent, Lipofectamine2000™ (LF2K), using fluorescence microscopy, flow cytometry, cell viability assays, and western blotting. We provide evidence that PEI transfection of mouse ESCs compares favorably to LF2K. Our optimized protocol for efficient transfection of mouse ESCs with PEI is detailed in this report.
