背景介绍
碱性成纤维细胞生长因子(FGF basic)是FGF家族成员,该家族包含至少23种具有35%-60%氨基酸同源性的有丝分裂原蛋白。与家族其他成员不同,酸性和碱性FGF均缺乏信号肽,其分泌机制明显不同于经典蛋白质分泌途径。碱性FGF已从神经组织、垂体、肾上腺皮质、黄体和胎盘等多种组织中分离获得。该因子虽含有四个半胱氨酸残基,但还原状态的碱性FGF仍能保持全部生物活性,表明二硫键对其功能并非必需。bFGF是人类胚胎干细胞培养基的关键组分,尽管其作用机制尚未明确,但该生长因子对维持细胞未分化状态至关重要。研究证实它能诱导gremlin表达,而后者可通过抑制骨形态发生蛋白的分化诱导作用来维持干性。无论是小鼠饲养层细胞依赖型培养系统,还是无饲养层无血清培养系统,bFGF都是不可或缺的组分。
