一般說明

碱性成纤维细胞生长因子（FGF-Basic） 存在于基底膜和内皮下细胞外基质中。FGF-Basic 在胚胎发育早期被诱导，它是胚胎干细胞（ESC） 和谱系定义的干细胞的多能性和自我更新所必需的（但不充分）； 其中它起到支持增殖和抑制分化的作用。hESC 的自我更新取决于激活素/Nodal/Smad2,3 分支的激活和 TGFβ 家族细胞信号传导程序的 BMP/GDF/Smad5 分支的抑制。FGF-Basic 是多能性节点支持的感受态因子。FGF-Basic 是维持干细胞特性所必需且充分的。它诱导人 ES 细胞中 Nodal 和 FGF-Basic 的表达。

應用

碱性成纤维细胞生长因子（FGF-Basic）是维持培养物中人胚胎干细胞和各种其它干细胞系，如间充质干 （基质） 细胞 （MSC） 所必需的。

外觀

从 20 mM Tris、1 M NaCl（pH 7.0，每1 μg BFGF含 50μg 牛血清白蛋白 (BSA)/1μg 脂联素）的 0.2 μm 过滤溶液冻干。

分析報告

FGF-Basic 的生物活性是在荧光测定中使用氧化还原敏感型染料刃天青进行测量。

Human embryonic stem cells (hESCs) self-renew indefinitely while maintaining pluripotency. The molecular mechanism underlying hESCs self-renewal and pluripotency is poorly understood. To identify the signaling pathway molecules that maintain the proliferation of hESCs, we performed a microarray analysis comparing an
