01General information

Description

NCI-H820是一种人类非小细胞肺癌(NSCLC)细胞系,来源于一名成年患者的肺腺癌。它是美国国立癌症研究院(NCI)肺癌细胞系的一部分,因其独特的遗传特征而被广泛用于靶向疗法研究。从形态上看,这种细胞具有上皮特征,并以粘附单层形式生长。它们通常在添加了 10%胎牛血清的 RPMI-1640 培养基中培养,并在标准细胞培养条件(37°C、5% CO₂)下保存。

从遗传学角度看,NCI-H820 的显著特征是携带表皮生长因子受体第 19 外显子缺失突变(E746-A750del),这是一种常见的活化突变,与对表皮生长因子受体酪氨酸激酶抑制剂(TKIs)的敏感性有关。然而,该患者还存在继发性表皮生长因子受体 T790M 突变,这是对第一代 TKIs(如厄洛替尼和吉非替尼)获得性耐药的公认机制。这种双重突变状态使NCI-H820成为研究耐药机制和评估奥希替尼等第三代表皮生长因子受体抑制剂的高度相关模型,奥希替尼可以克服T790M介导的耐药性。

除了表皮生长因子受体突变外,NCI-H820 还被用于研究自分泌信号环路和生长因子受体通路。研究表明,它表达 I 型胰岛素样生长因子受体(IGF-1R),有助于存活和增殖信号传导。它的双重突变特征和受体酪氨酸激酶的表达使其成为临床前研究的重要工具,这些研究主要针对表皮生长因子受体突变型 NSCLC 的耐药性、联合治疗策略和个性化治疗方法的开发。

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。
