01General information

Description

NCI-H1755 是一种从肺腺癌中提取的人类非小细胞肺癌(NSCLC)细胞系。它是美国国立癌症研究所(NCI)胸腔癌模型小组的一部分,该小组旨在支持肺癌生物学和治疗反应的转化研究。该细胞系表现出 KRAS 突变,这是许多肺腺癌的共同特征,会导致 MAPK 和 PI3K 信号通路的持续激活,促进细胞失控生长并对某些靶向疗法产生抗药性。

NCI-H1755 已被纳入多个大规模功能基因组学和药物基因组学筛选,包括蛋白质表达和对靶向药物反应的筛选。它的分子特征表明它在 PI3K/AKT 和 RAS/RAF/MEK 信号通路中具有活性,这使它成为评估 MEK 抑制剂和其他针对下游效应分子的药物效果的重要工具。该细胞系还促进了以上皮极性为重点的研究,研究发现,在包括肺腺癌在内的各种上皮癌中,极性复合基因(如 PARD3)的结构发生了紊乱。

在体外,NCI-H1755 细胞以粘附单层形式生长,并呈现上皮形态。它们在标准培养条件下,在添加了 10%胎牛血清的 RPMI-1640 培养基中进行培养。由于其生长特性、突变特征具有可重复性,而且已被纳入分子肿瘤学数据集,NCI-H1755 成为研究 KRAS 突变 NSCLC 的肿瘤进展机制、耐药性和潜在治疗靶点的常用模型。

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。
