背景(Background)
干细胞因子也称为SCF、试剂盒配体、KL、钢因子、KITLG、FPH2、KL-1、Kitl、MGF、SCF、SF或SHEP7,是一种与c-kit受体(CD117)结合的细胞因子。SCF既可以作为跨膜蛋白存在,也可以作为可溶性蛋白存在。这种细胞因子在造血(血细胞的形成)、精子发生和黑色素生成中起着重要作用。该蛋白的可溶性和跨膜形式是通过同一R转录物的选择性剪接形成的。可溶性和跨膜SCF由成纤维细胞和内皮细胞产生。可溶性SCF的分子量为18.5 KDa,形成二聚体。SCF在胚胎发育过程中的造血过程中起着重要作用。造血发生的部位,如胎儿肝脏和骨髓,都表达SCF。在发育过程中,SCF的存在在黑素细胞的定位中也起着重要作用,黑素细胞是产生黑色素和控制色素沉着的细胞。SCF在骨髓干细胞生态位中对HSC的调节中起着重要作用。SCF可以与其他细胞因子一起用于培养HSC和造血祖细胞。这些细胞在体外(体外)的扩增将使骨髓移植取得进展,在骨髓移植中,造血干细胞被转移到患者体内以重建血液形成。
