01General information

Description

HCC4006 是一种源自肺腺癌的人类非小细胞肺癌(NSCLC)细胞系。它的特点是表皮生长因子受体(EGFR)基因的第 19 号外显子缺失,这使它对 EGFR 酪氨酸激酶抑制剂(TKIs)(如厄洛替尼和吉非替尼)特别敏感。这一特点使 HCC4006 成为研究表皮生长因子受体突变 NSCLC 和表皮生长因子受体靶向疗法耐药机制的广泛应用模型。在《癌细胞系百科全书》(CCLE)中,HCC4006 在基因组、转录组和表观遗传学水平上进行了全面的分析,证实了它对表皮生长因子受体抑制的高敏感性,并突出了它作为药物基因组参考模型的用途。

高分辨率基因组研究显示,与其他 NSCLC 模型相比,HCC4006 的核型相对简单,这有助于更清晰地解读药物反应和基因组改变。它缺乏常见的耐药性突变,如表皮生长因子受体(EGFR)基因中的 T790M,因此适合用于建立初始治疗反应模型。不过,抗药性可以在体外诱导,使研究人员能够研究获得性抗药性的机制。例如,HCC4006 对表皮生长因子受体 TKIs 的耐药性与上皮-间质转化(EMT)和替代信号通路的激活(如 AXL 激酶过表达)有关。

在对细胞系和原发肿瘤进行大规模转录组比较时,也对 HCC4006 进行了评估。它是与原发肿瘤基因表达谱有适度相关性的肺腺癌细胞系之一,但相关程度会因用于比较的肿瘤样本的纯度而异。这些分析强调了 HCC4006 在模拟肺腺癌某些分子方面的相关性,特别是与表皮生长因子受体驱动的肿瘤发生相关的方面,同时也强调了它在完全再现原发肿瘤异质性方面的局限性。

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.

07Quality 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。
