01General information

Description

NCI-H889是一种具有神经内分泌特征的人类小细胞肺癌(SCLC)细胞系。该细胞系源自成人患者,根据形态学和分子学标准被归类为经典型小细胞肺癌模型。细胞呈悬浮生长状态,并展现出小细胞肺癌典型的圆形至椭圆形形态。 该细胞系表达多种神经内分泌标志物,已被广泛应用于研究此类侵袭性肺癌亚型的机制及药理学研究。

功能上,NCI-H889以通过胰岛素样生长因子II(IGF-II)及其受体IGF-R的自分泌信号传导为特征。尽管IGF-I mRNA在多种肺癌细胞系中普遍存在,但IGF-I蛋白的直接分泌却较为罕见;在NCI-H889中,参与生长刺激的主要配体是IGF-II。 该现象与支持IGF-II/IGF-R信号回路作为小细胞肺癌细胞系自主生长关键驱动因素的研究结果一致。这些自主调节机制使NCI-H889成为研究IGF介导的促有丝分裂信号及其治疗性阻断的理想模型系统。

NCI-H889细胞的表观遗传学分析还揭示了药物反应调控机制。甲基化谱显示多个参与DNA损伤应答、细胞周期调控及转录控制的基因发生改变。 例如,在揭示SLFN11(与DNA损伤剂敏感性相关)和EZH2(小细胞肺癌中常高表达的组蛋白甲基转移酶)等基因差异甲基化与表达的研究中,NCI-H889均被纳入分析。这些特征共同确立了NCI-H889作为探索神经内分泌肺肿瘤治疗靶点的临床前模型的价值。

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。
