細(xì)胞增殖實驗
摘要:在293T細(xì)胞中過表達(dá)human Oct-4基因, 通過CCK-8方法對Oct-4過表達(dá)細(xì)胞組、空細(xì)胞組與陰性對照組的細(xì)胞增殖進(jìn)行定量,研究Oct-4基因?qū)?93T細(xì)胞增殖能力的影響。實驗結(jié)果顯示Oct-4基因的表達(dá)促進(jìn)293T細(xì)胞的增殖能力。為進(jìn)一步深入研究Oct-4基因的功能提供實驗數(shù)據(jù)。
關(guān)鍵詞:Oct-4,CCK??-8,細(xì)胞增殖,293T
一、?實驗原理
細(xì)胞增殖是生物體的重要生命特征,細(xì)胞以分裂的方式進(jìn)行增殖。單細(xì)胞生物,以細(xì)胞分裂的方式產(chǎn)生新的個體。多細(xì)胞生物,以細(xì)胞分裂的方式產(chǎn)生新的細(xì)胞,用來補(bǔ)充體內(nèi)衰老和死亡的細(xì)胞;同時,多細(xì)胞生物可以由一個受精卵,經(jīng)過細(xì)胞的分裂和分化,最終發(fā)育成一個新的多細(xì)胞個體。通過細(xì)胞分裂,可以將復(fù)制的遺傳物質(zhì),平均地分配到兩個子細(xì)胞中去。細(xì)胞增殖是生物體生長、發(fā)育、繁殖和遺傳的基礎(chǔ)。細(xì)胞增殖的研究方法有很多,主要包括:BrdU,EdU,CCK-8等方法。
二、?實驗?zāi)康?/strong>
用質(zhì)粒Oct-4-EGFP轉(zhuǎn)染后的細(xì)胞與正常細(xì)胞組、陰性對照組進(jìn)行比較分析,考察Oct-4基因?qū)?xì)胞的增殖能力產(chǎn)生的影響。采用CCK-8 法對3組細(xì)胞進(jìn)行比較分析。
三、?實驗步驟
實驗共分以下5個主要步驟:
1.?收集細(xì)胞:
收集細(xì)胞:將293T細(xì)胞消化后制成單細(xì)胞懸液,計數(shù)后,每組細(xì)胞配成一定濃度的單細(xì)胞懸液。
2.?細(xì)胞鋪板:
細(xì)胞配成2×104cell/ml后,每孔鋪100μl細(xì)胞,即2000cell/well。一般每個樣品設(shè)5~6個復(fù)孔,邊緣孔加100μl無菌水或者PBS。37℃,5%CO2培養(yǎng)箱中培養(yǎng)。
3.?質(zhì)粒轉(zhuǎn)染:
???? 16h后,按照轉(zhuǎn)染試劑說明書轉(zhuǎn)染細(xì)胞(0.2μg質(zhì)粒,0.5μl和元生物轉(zhuǎn)染試劑)。
4.?細(xì)胞培養(yǎng)6、24、48、72h后CCK-8處理,酶標(biāo)儀檢測:
轉(zhuǎn)染后, 在每個檢測時間點加入10μl的CCK-8于孔中,無需換液。3h后,酶標(biāo)儀檢測450nm OD值。
5.?統(tǒng)計分析:
GraphPad Prism(Ver5,GraphPad Software) 作圖,并進(jìn)行雙側(cè)t檢驗。

結(jié)論:從實驗結(jié)果統(tǒng)計分析可以發(fā)現(xiàn),293T細(xì)胞在過表達(dá)Oct-4-EGFP后,72h時增殖能力均高于空細(xì)胞組以及對照組(p<0.001)。
