01General information

Description

COR-L23 是一种源自大细胞肺癌(LCLC)成年患者的人肺癌细胞系。该细胞系由临床肿瘤样本建立,是一种具有上皮特征的非小细胞肺癌模型。 在体外培养中,COR-L23呈贴壁单层生长,并使用添加胎牛血清的标准 RPMI 培养基维持培养。该细胞系是直接源自患者标本的肺癌模型系列的一部分,旨在促进对肺肿瘤发生分子和细胞机制的研究。

表型特征分析表明,COR-L23在形态和生物标志物表达方面均与经典的小细胞肺癌细胞系不同。 与通常呈悬浮聚集体生长且强烈表达神经内分泌标志物的典型小细胞肺癌模型不同,COR-L23表现出与大细胞癌一致的特征,包括小细胞肺癌中常见的神经内分泌相关酶和标志物表达降低。这些差异凸显了其作为研究非小细胞肺癌生物学模型以及比较不同肺癌亚型分子特征的重要价值。

对包含COR衍生模型的肺癌细胞系组合进行的遗传学和细胞遗传学分析,揭示了与肺部恶性肿瘤常见的染色体异常及致癌基因改变。此类改变可能涉及致癌基因家族的失调以及促进肿瘤进展的染色体结构变化。基于这些分子特征及其表型特征明确,COR-L23被广泛用于研究肺癌信号传导通路、药物反应以及肿瘤细胞增殖和存活的机制。

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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.

  7. Follow the procedure described under Post-Thaw Recovery

07Quality control and cryopreservation

Freeze medium
作为冷冻保存培养基,我们使用完全生长培养基+10% DMSO,以获得足够的解冻后存活率。
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。
