背景介绍
Stem121:抗人类细胞质蛋白的小鼠抗体
1. Stem121是什么?
· Stem121是小鼠来源的单克隆抗体,它特异性地识别人类细胞(特别是人类神经细胞)细胞质中的某个抗原。
· Stem121在反应属性上有两个主要特点:
1) 它所识别的抗原不在细胞核内,可以特异性的识别细胞质内的抗原;
2)它与小鼠、大鼠、猴子细胞的细胞质没有反应性。
2. Stem121的应用
· 小鼠、大鼠、猴子是目前干细胞治疗研究者常用的模式动物。通常,研究者将人类的神经干细胞注射进入这些模式动物的脑部,然后观察这些细胞是否可以在动物的脑部存活、生长、分化、迁移。因此,必须可靠而且准确地示踪在动物体内的人类神经干细胞。
· Stem121抗体是可以对人类细胞细胞质进行标记的抗体。
· 对于输入的人神经干细胞,既标记细胞核又标记细胞质,意味着更加可靠、更加准确。如下图所示,人类的神经干细胞被注射进入大鼠的脑部,蓝色标记是某种识别人类细胞的细胞核的抗体,绿色标记是识别人类细胞细胞质的Stem121抗体,红色标记是识别人类细胞某种发炎症状的抗体。在A部分的左图左下角有个箭头指示的细胞,具备蓝色与绿色标记,这说明这个细胞确定是人类细胞而非大鼠细胞;右图右下角的箭头指示同一个细胞,没有绿色标记,说明这个人类细胞并没有出现发炎症状。而且,如果实验的设计目的是观察人类的神经细胞的细胞质能否进入到人类或是动物细胞的细胞核里面,那么就需要Stem121对人类细胞质进行标记。
· 另外,需要注意,Stem121在之前发表的文章中,也被称作SC121。(Kelly S, et al .Transplanted human fetal neural stem cells survive, migrate, and differentiate in ischemic rat cerebral cortex. PNAS,2004,101: 11839-11844.)
