01General information

Description

NCI-H1993 细胞系是一种人类非小细胞肺癌(NSCLC)模型,来源于一名男性患者的转移部位。该细胞系被归类为腺癌,其显著特征是 MET 基因扩增,这种扩增会促进肿瘤生长并增强侵袭性特征。NCI-H1993 中的 MET 扩增会导致肝细胞生长因子(HGF)/MET 信号通路的持续激活,促进细胞增殖、存活和转移。这使得 NCI-H1993 成为研究 MET 驱动的肿瘤发生和评估靶向治疗药物的重要模型。

NCI-H1993 已被广泛用于克唑替尼和泰泊替尼等 MET 抑制剂的临床前评估。这些抑制剂在抑制 MET 信号传导、减少肿瘤细胞增殖和诱导细胞凋亡方面具有显著疗效。该细胞系对 MET 抑制的反应性突显了它在旨在开发 MET 驱动型癌症治疗方法的转化研究中的作用。除 MET 靶向研究外,NCI-H1993 还被用于探索 MET 信号与其他致癌途径(如 PI3K/AKT 和 RAS/RAF/ERK 级联)之间的相互作用。

最近对 NCI-H1993 对糖皮质激素受体(GR)激动剂(如地塞米松)的反应进行的研究揭示了新的见解。该细胞系在 G1/S 期转变时表现出 GR 介导的生长停滞,同时伴有代谢重编程和迁移减少。这些研究结果表明,GR激动剂和MET抑制剂可能成为治疗晚期NSCLC的组合治疗策略。NCI-H1993强大的遗传和分子特征继续支持其作为一种关键工具,促进对肺腺癌生物学和疗法开发的了解。

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。
