背景介紹

Stem121：抗人類(lèi)細(xì)胞質(zhì)蛋白的小鼠抗體

1. Stem121是什么？

· Stem121是小鼠來(lái)源的單克隆抗體，它特異性地識(shí)別人類(lèi)細(xì)胞（特別是人類(lèi)神經(jīng)細(xì)胞）細(xì)胞質(zhì)中的某個(gè)抗原。

· Stem121在反應(yīng)屬性上有兩個(gè)主要特點(diǎn)：

    1) 它所識(shí)別的抗原不在細(xì)胞核內(nèi)，可以特異性的識(shí)別細(xì)胞質(zhì)內(nèi)的抗原；

    2）它與小鼠、大鼠、猴子細(xì)胞的細(xì)胞質(zhì)沒(méi)有反應(yīng)性。

2. Stem121的應(yīng)用

· 小鼠、大鼠、猴子是目前干細(xì)胞治療研究者常用的模式動(dòng)物。通常，研究者將人類(lèi)的神經(jīng)干細(xì)胞注射進(jìn)入這些模式動(dòng)物的腦部，然后觀察這些細(xì)胞是否可以在動(dòng)物的腦部存活、生長(zhǎng)、分化、遷移。因此，必須可靠而且準(zhǔn)確地示蹤在動(dòng)物體內(nèi)的人類(lèi)神經(jīng)干細(xì)胞。

· Stem121抗體是可以對(duì)人類(lèi)細(xì)胞細(xì)胞質(zhì)進(jìn)行標(biāo)記的抗體。

· 對(duì)于輸入的人神經(jīng)干細(xì)胞，既標(biāo)記細(xì)胞核又標(biāo)記細(xì)胞質(zhì)，意味著更加可靠、更加準(zhǔn)確。如下圖所示，人類(lèi)的神經(jīng)干細(xì)胞被注射進(jìn)入大鼠的腦部，藍(lán)色標(biāo)記是某種識(shí)別人類(lèi)細(xì)胞的細(xì)胞核的抗體，綠色標(biāo)記是識(shí)別人類(lèi)細(xì)胞細(xì)胞質(zhì)的Stem121抗體，紅色標(biāo)記是識(shí)別人類(lèi)細(xì)胞某種發(fā)炎癥狀的抗體。在A部分的左圖左下角有個(gè)箭頭指示的細(xì)胞，具備藍(lán)色與綠色標(biāo)記，這說(shuō)明這個(gè)細(xì)胞確定是人類(lèi)細(xì)胞而非大鼠細(xì)胞；右圖右下角的箭頭指示同一個(gè)細(xì)胞，沒(méi)有綠色標(biāo)記，說(shuō)明這個(gè)人類(lèi)細(xì)胞并沒(méi)有出現(xiàn)發(fā)炎癥狀。而且，如果實(shí)驗(yàn)的設(shè)計(jì)目的是觀察人類(lèi)的神經(jīng)細(xì)胞的細(xì)胞質(zhì)能否進(jìn)入到人類(lèi)或是動(dòng)物細(xì)胞的細(xì)胞核里面，那么就需要Stem121對(duì)人類(lèi)細(xì)胞質(zhì)進(jìn)行標(biāo)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.）
