01General information

Description

NCI-H1650 细胞系源自人类非小细胞肺癌 (NSCLC),特别是腺癌,因其独特的遗传特征和与药物测试的相关性而被广泛用于癌症研究。这种细胞系具有关键致癌和抑瘤通路突变的特征,包括 PTEN 基因缺失和表皮生长因子受体激活突变。这些基因改变使NCI-H1650成为研究NSCLC肿瘤发生和耐药性机制的合适模型,特别是在针对表皮生长因子受体信号通路的靶向疗法方面。

NCI-H1650中PTEN的缺失导致磷酸酶活性丧失,从而使PI3K/AKT信号通路失调,导致肿瘤进展和对某些治疗药物产生耐药性。肺腺癌中常见的表皮生长因子受体(EGFR)激活突变使细胞系对厄洛替尼等酪氨酸激酶抑制剂特别敏感。然而,由于这些基因变化的同时存在,往往需要采用联合疗法来克服适应性耐药机制,这涉及补偿性信号通路,如mTOR或MET。

除了其遗传和信号转导特征外,NCI-H1650 还被纳入了许多研究中,这些研究考察了体细胞突变、拷贝数变异和癌细胞系的表观遗传学改变。它对表皮生长因子受体(EGFR)和 PI3K 通路抑制剂的反应突显了其在临床前药物发现和个性化医疗策略中的作用。该细胞系是研究肺腺癌致癌因素和治疗弱点之间相互作用的代表性模型。

05Handling and culture

Culture medium
RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Dissociation reagent
Accutase
Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。
Fluid renewal
每周 2 至 3 次
Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

06Quality control and cryopreservation

Sterility

使用基于 PCR 的检测方法和基于发光的支原体检测方法排除支原体污染。

为确保没有细菌、真菌或酵母菌污染,每天都要对细胞培养物进行目视检查。

Freeze medium
我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
Storage conditions

如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。

Shipping conditions

冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。
