美國Oct4-GFP報告基因小鼠胚胎干細(xì)胞

美國PrimCells干細(xì)胞：PrimCells提供多種報告基因敲進(jìn)的小鼠胚胎干細(xì)胞，該類細(xì)胞皆在原始基因座上敲入熒光報告基因，從而使熒光蛋白的表達(dá)能真實反映原基因座附近的表達(dá)調(diào)控狀況。該類細(xì)胞作為研究胚胎干細(xì)胞自更新和定向分化的有力工具，受到多家有名研究所研究人員的青睞。

美國Oct4-GFP報告基因小鼠胚胎干細(xì)胞

Oct4 is a transcriptional factor from POU protein family. It is one of the most important markers for undifferentiated embryonic stem cells and is required to maintain the self-renwal of mESCs¹. Oct4 is also associated with human germ cell tumors².

PrimCells is proud to isolate and provide to the research community the culture of Oct4-EGFP ESCs from transgenic knock-in mice. These cells were cultured in standard ESCs medium on gelatin coated plates and be used as a powerful tool to examine the mechanism of self-renwal of mouse embryonic stem cells. Oct4-GFP mESCs should be maintained in the stem cell culture medium with LIF to maintain the pluripotent state (Figure 1).

Note: This cell line is puromycin-resistent. 

Figure 1. Oct4-GFP mESCs show GFP signals when maintained in ESC medium (Left). The differentiated cells lose the GFP signals in the absence of LIF (Right).
