背景介紹
Stem121:抗人類細胞質蛋白的小鼠抗體
1. Stem121是什么?
· Stem121是小鼠來源的單克隆抗體,它特異性地識別人類細胞(特別是人類神經細胞)細胞質中的某個抗原。
· Stem121在反應屬性上有兩個主要特點:
1) 它所識別的抗原不在細胞核內,可以特異性的識別細胞質內的抗原;
2)它與小鼠、大鼠、猴子細胞的細胞質沒有反應性。
2. Stem121的應用
· 小鼠、大鼠、猴子是目前干細胞治療研究者常用的模式動物。通常,研究者將人類的神經干細胞注射進入這些模式動物的腦部,然后觀察這些細胞是否可以在動物的腦部存活、生長、分化、遷移。因此,必須可靠而且準確地示蹤在動物體內的人類神經干細胞。
· Stem121抗體是可以對人類細胞細胞質進行標記的抗體。
· 對于輸入的人神經干細胞,既標記細胞核又標記細胞質,意味著更加可靠、更加準確。如下圖所示,人類的神經干細胞被注射進入大鼠的腦部,藍色標記是某種識別人類細胞的細胞核的抗體,綠色標記是識別人類細胞細胞質的Stem121抗體,紅色標記是識別人類細胞某種發(fā)炎癥狀的抗體。在A部分的左圖左下角有個箭頭指示的細胞,具備藍色與綠色標記,這說明這個細胞確定是人類細胞而非大鼠細胞;右圖右下角的箭頭指示同一個細胞,沒有綠色標記,說明這個人類細胞并沒有出現發(fā)炎癥狀。而且,如果實驗的設計目的是觀察人類的神經細胞的細胞質能否進入到人類或是動物細胞的細胞核里面,那么就需要Stem121對人類細胞質進行標記。
· 另外,需要注意,Stem121在之前發(fā)表的文章中,也被稱作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.)
