01General information

Description

PC-9 细胞系来源于人类肺腺癌,是非小细胞肺癌(NSCLC)的一种亚型。这种细胞系尤其值得注意的是,它携带表皮生长因子受体基因的激活突变,特别是第 19 号外显子缺失(E746_A750del),这是 NSCLC 中常见的驱动突变。这种突变使 PC-9 成为研究表皮生长因子受体(EGFR)驱动的癌症生物学以及评估吉非替尼和厄洛替尼等酪氨酸激酶抑制剂(TKIs)疗效的宝贵模型。

PC-9 细胞已被广泛用于研究表皮生长因子受体 TKIs 的耐药机制,特别是 T790M 等二次突变的出现。这些研究为奥希替尼等第三代抑制剂的开发提供了依据,奥希替尼同时针对原发性表皮生长因子受体突变和耐药性相关改变。该细胞系还对其他针对下游信号通路(包括参与 PI3K/AKT 和 MAPK 信号级联的通路)的抑制剂表现出敏感性,突出了其在癌症转化研究中的作用。

除了遗传和药理特性外,PC-9 还被纳入了高通量药物筛选计划,有助于鉴定对表皮生长因子受体突变的 NSCLC 具有选择性活性的化合物。该品系具有良好的基因组特征和一致的体外表型行为,使其成为肺癌基础研究和应用研究的基石,尤其是在靶向治疗和联合治疗方面。

05Handling 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
将悬浮细胞收集到 15 毫升试管中,用不含钙和镁的 PBS(T25 烧瓶用 3-5 毫升,T75 烧瓶用 5-10 毫升)轻轻清洗粘附的细胞。涂抹 Accutase(T25 烧瓶 1-2 毫升,T75 烧瓶 2.5 毫升),确保完全覆盖细胞层。让细胞在 37°C 孵育 10-15 分钟。孵育后,将悬浮细胞和粘附细胞混合并离心。离心后,小心重悬细胞团,并将细胞悬浮液转移到装有新鲜培养基的新烧瓶中。
Fluid renewal
每周 1 至 2 次
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.

06Quality 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。
