產(chǎn)品詳情介紹
干細(xì)胞因子（Stem cell factor, SCF），也稱為KIT配體，是一種結(jié)合酪氨酸激酶受體（c-kit）的細(xì)胞因子。SCF也被稱為“c-kit配體”[1-2]。SCF是一種對造血干細(xì)胞和其他造血祖細(xì)胞的存活、增殖和分化很重要的生長因子。其作用之一是將紅細(xì)胞系列中最早的紅細(xì)胞前體BFU-E（突發(fā)形成單位紅細(xì)胞）細(xì)胞轉(zhuǎn)變?yōu)镃FU-E（集落形成單位紅細(xì)胞）[3]。重組SCF可以與G-CSF聯(lián)合使用，提高外周血中CD34+細(xì)胞的濃度，動員外周血祖細(xì)胞（PBPC），快速恢復(fù)癌癥患者的骨髓造血功能。在自體造血干細(xì)胞移植中，SCF的使用可以增加動員到外周血的造血干細(xì)胞數(shù)量，有助于收集足夠數(shù)量的干細(xì)胞以進行移植[4]。
