01General information

Description

NCI-H2052 是一种人类间皮瘤细胞系,来源于一名被诊断为恶性间皮瘤的成年患者的胸膜活检标本。作为 NCI 海军肿瘤内科细胞系面板的一部分,它因其可重复生长的特性和明确的组织学来源而被广泛用于间皮瘤研究。该细胞系是根据 IRB 批准的方案建立的,旨在生成临床注释的癌症模型,因此对于将体外行为与患者疾病特征联系起来的转化研究特别有价值。

从表型上看,NCI-H2052呈现上皮形态,这一特征与间皮瘤的上皮样亚型一致。这些细胞在体外生长为粘附单层细胞,并在补充了 10%胎牛血清的 RPMI-1640 培养基中培养。基因组剖析发现了间皮瘤特有的改变,包括涉及 CDKN2A 和 NF2 的通路失调,尽管 NCI-H2052 特异性地保留了野生型 BAP1,而且与其他间皮瘤模型相比,其突变负荷相对较低。这些分子特征使 NCI-H2052 成为研究间皮瘤发病机制和治疗反应的参考模型,尤其是在排除 BAP1 驱动表型的情况下。

该细胞系已被纳入综合药物基因组学和转录组学数据集,有助于对间皮瘤亚型和治疗敏感性进行比较分析。它对以 PI3K/mTOR 轴为靶点的药物表现出适度的反应性,已被用于高通量筛选平台,以确定潜在的合成致死相互作用和新型治疗方法。由于其分子特征和来源,NCI-H2052 仍是间皮瘤药物开发和分子特征研究的基石。

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。
