細(xì)胞系特征 | ||
細(xì)胞株名稱:A549/DDP人肺癌耐藥株 種屬:人 組織來源:肺癌 生長特性:貼壁生長 形態(tài)特征:上皮細(xì)胞 微生物及支原體檢測:陰性 安全性:所有腫瘤和病毒轉(zhuǎn)染的細(xì)胞均視為有潛在的生物危害性,必須在二級生物安全臺內(nèi)操作,,并請注意防護(hù),,所有廢液及接觸過此細(xì)胞的器皿需高壓滅菌后方能丟棄。 | ||
培養(yǎng)條件:
| 培養(yǎng)基:90%RPMI-1640+10%胎牛血清+2000ng/ml DDP 血清我們推薦用: GIBCOFBS-10099-141或HYCLONEFBS-SH30084.03,。 培養(yǎng)條件:37.0C carbon dioxide(CO2),5% | |
傳代方法:
| 收到細(xì)胞后,在倒置鏡下(是在4X物鏡)觀察整個細(xì)胞生長情況,。 (一)如果細(xì)胞未長滿,,用75%酒精噴灑整個瓶消毒后放到超菌臺內(nèi),嚴(yán)格無菌操作,,打開細(xì)胞培養(yǎng)瓶,,吸出培養(yǎng)液,換 10ml新鮮培養(yǎng)液后繼續(xù)培養(yǎng),。 (二)如果細(xì)胞已長滿,,即可進(jìn)行傳代培養(yǎng)。具體步驟如下: 1. 棄去培養(yǎng)液,,用PBS(不含鈣,鎂離子)洗1-2次,。 2. 加0.7-1ml消化液(0.25%Trypsin-0.53mM EDTA)于培養(yǎng)瓶中,用力拍打瓶壁,,期間每隔 5-10s放到顯微鏡下觀察,,直至50-70%的細(xì)胞脫落后,加入2ml 以上培養(yǎng)基中止消化,。 3. 按6-8ml/瓶補(bǔ)加培養(yǎng)基,,輕輕打勻后吸出一半,分到新的培養(yǎng)瓶中,。如果沒有特別說明,,收到細(xì)胞后的次傳代一般是一傳二。 注:1,、觀察細(xì)胞在低倍鏡(4或5X物鏡)下進(jìn)行,,否則不能準(zhǔn)確判斷細(xì)胞的傳代密度??醇?xì)胞的形態(tài)請在10X或20X物鏡下,。 2、瓶中運輸培養(yǎng)基不能重復(fù)再用,請換用加雙抗的新培養(yǎng)基,,細(xì)胞凍存后,培養(yǎng)基中可不加任何抗生素,。 3、有些細(xì)胞貼壁不牢,如發(fā)現(xiàn)貼壁細(xì)胞有脫落,,可離心吹打后接種到新瓶內(nèi),。 4、收到細(xì)胞后,,若發(fā)現(xiàn)培養(yǎng)瓶破損,、有液溢出及細(xì)胞有污染,請及時與我們聯(lián)系,。..

Autophagy is an essential catabolic process in T cells
apoptosis, marked by greater caspase-9 expression [6, 78, 80]. In addition, in a Beclin-1-
deficient T cell model, decreased numbers of CD4+ and CD8+ T cells correlated with
increased rates of apoptotic cell death [79]. Beclin1-deficient cells also had increased levels of pro-caspase 3 and 8, Bim and Bcl-2 [79]. Autophagy (more specifically, mitophagy) has a
key role in regulating the homeostasis of mitochondria by controlling their turnover as a
quality control mechanism [78, 80]. Consequently, increased apoptotic cell death in
autophagy-deficient cells has been linked to inefficient clearance and accumulation of
