GS2-M小鼠ES胚胎和iPS誘導(dǎo)多能干細(xì)胞培養(yǎng)基
英文名稱(chēng)：Cellartis GS2-M Mouse ES and iPS stem culture medium
中文名稱(chēng)：Cellartis GS2-M小鼠胚胎干細(xì)胞和誘導(dǎo)多能干細(xì)胞培養(yǎng)基
用途：小鼠（mouse）胚胎干細(xì)胞(ES)和誘導(dǎo)多能干細(xì)胞(iPS)細(xì)胞的維持培養(yǎng)
保存：基礎(chǔ)培養(yǎng)基-20ºC；添加劑-80ºC
小鼠胚胎干細(xì)胞是*被體外分離培養(yǎng)并建系的干細(xì)胞，目前其相關(guān)研究已經(jīng)比較完善并投入到了實(shí)際應(yīng)用中，很多其他種屬的干細(xì)胞研究也都會(huì)參考小鼠胚胎干細(xì)胞的研究成果。一個(gè)好的小鼠胚胎干細(xì)胞體外培養(yǎng)體系，需要同時(shí)滿(mǎn)足操作簡(jiǎn)便、結(jié)果穩(wěn)定、增長(zhǎng)迅速、可重復(fù)性好、有效維持胚胎干細(xì)胞處于Ground-state等特點(diǎn)。
Cellartis 提供一款小鼠胚胎干細(xì)胞培養(yǎng)基GS2‐M，其成分確定、無(wú)血清，支持無(wú)飼養(yǎng)層培養(yǎng)，通過(guò)添加兩種特別的小分子抑制劑（CHIR99021，PD0325901=2i）來(lái)阻斷分化信號(hào)通路GSK3β和 ERK/MEK，進(jìn)而維持小鼠胚胎干細(xì)胞處于Ground state。值得一提的是，使用GS2-M培養(yǎng)基培養(yǎng)的小鼠胚胎干細(xì)胞，與添加血清和LIF的培養(yǎng)基培養(yǎng)相比，可以更好地維持小鼠胚胎干細(xì)胞處于Ground-state。
GS2-M與細(xì)胞因子leukemia inhibitory factor (LIF)一同使用時(shí)，可以通過(guò)調(diào)控Nanog信號(hào)通路實(shí)現(xiàn)將partial or pre‐iPS cells轉(zhuǎn)化成為fully pluripotent iPS cells(1, 2)。
GS2‐M is a compley defined, serum‐free cell culture media formulation for the generation and long-term maintenance of human and mouse embryonic stem (ES) and induced pluripotent stem (iPS) cell lines. The medium contains two selective small molecule inhibitors that block differentiation‐inducing signals and promote cell survival.
GS2-M medium can be used in combination with the self-renewal cytokine leukemia inhibitory factor (LIF) to convert partial or pre‐iPS cells from mouse into fully pluripotent iPS cells via upregulation of Nanog (1, 2).

組份：
100 ml medium
100 µl 2i inhibitor supplement
自備試劑：
A. For mouse ES and iPS cells.
Culture vessels are pre-coated with either 0.1% gelatin type A in PBS solution (at room temperature for 15 minutes or more), or precoated sequentially with 0.01% poly-L-ornithine hydrobromide (at 37℃ for 30 minutes or more), washing twice with PBS, followed by 10 μg/mL laminin in PBS (at 37℃ for 3 hours or more).
B. For human iPS cells.
Please refer to Wang W, et al. (2011) reference for more detailed reagent and culture requirements to generate and propagate ‘naïve’ human iPS cells4.
A.對(duì)于小鼠ES和iPS細(xì)胞。
