01General information

Description

NCI-H322 是一种人类非小细胞肺癌 (NSCLC) 细胞系,来源于一名患有支气管肺泡癌(腺癌的一种组织学亚型)的成年患者。该细胞系由美国国家癌症研究所海军肿瘤内科建立,是为研究和治疗开发建立临床注释肺癌模型的综合努力的一部分。NCI-H322 在体外呈粘附上皮形态,通常在标准细胞培养条件下用 RPMI-1640 培养基培养,并补充 10% 的胎牛血清。

对 NCI-H322 的分子分析表明,它携带 KRAS 突变,该突变通过 MAPK/ERK 和 PI3K/AKT 通路产生致癌信号。这种突变使细胞系对表皮生长因子受体靶向疗法产生抗药性,因此适合用于以 KRAS 驱动的肺腺癌为重点的研究。此外,该细胞系的表皮生长因子受体(EGFR)和TP53均为野生型,为剖析依赖于KRAS的肿瘤生物学提供了明确的遗传背景。其转录和蛋白质组数据已被纳入癌症细胞系百科全书(CCLE)等大型数据集,为分析细胞系特异性弱点和药物反应模式做出了贡献。

NCI-H322 被广泛用于药理筛选和机理研究,以探索对 MEK 抑制剂、PI3K 通路抑制剂和化疗药物的敏感性。NCI-H322在各项研究中的表现始终如一,其突变情况记录详实,是KRAS突变NSCLC的重要临床前模型,也是了解肺腺癌肿瘤异质性和耐药性的重要参考。

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。
