01General information

Description

NCI-H358又称H-358或NCIH358,是一种上皮样细胞系,来源于一名支气管肺泡癌(非小细胞肺癌(NSCLC)的一种亚型)患者。这些细胞具有典型的克拉拉细胞超微结构特征,如特定的细胞质特征。NCI-H358 细胞与以 NSCLC 为重点的癌症研究特别相关,尤其是在探索肺腺癌的生物学和治疗方面。

这种细胞系对于研究针对表皮生长因子受体(EGFR)的疗法的有效性至关重要,因为表皮生长因子受体的突变是治疗 NSCLC 的重点。此外,NCI-H358 细胞对于研究 KRAS 基因突变的作用也很有价值,KRAS 基因突变在肺癌中很普遍,已知会驱动致癌活性。研究 NCI-H358 细胞中的这些突变有助于阐明肺癌进展和耐药性的分子途径。

NCI-H358细胞系存在p53的同源染色体缺失,而p53是一种主要的肿瘤抑制因子。H358 肺癌细胞系还用于评估新型治疗方法的潜力,如 SOS1 PROTACs,其目的是针对特定的致癌途径。

总之,NCI-H358 细胞系来源于支气管肺泡癌,是 NSCLC 研究的重要工具。它有助于研究表皮生长因子受体靶向疗法和 KRAS 突变在肺癌中的作用。它在癌症研究中的应用扩展到开发新的治疗策略,旨在减轻致癌基因突变的影响,改善肺癌患者的预后。

06Handling 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。
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。
