01General information

Description

OVCAR-4 是一种源自成年上皮性卵巢癌患者的人卵巢癌细胞系,该患者此前曾接受过联合化疗。它属于一套用于模拟临床药物耐药性和肿瘤异质性的卵巢癌细胞系。作为该系列的一部分,OVCAR-4 反映了暴露于顺铂和阿霉素等化疗药物后的肿瘤特征,因此对于研究化疗反应和耐药机制具有特别重要的价值。

分子分析表明,OVCAR-4 表现出可检测到的金属硫蛋白 mRNA 表达,该蛋白参与金属离子结合和细胞解毒通路。 值得注意的是,顺铂暴露仅导致该细胞系中金属硫蛋白表达轻微增加,这表明尽管金属硫蛋白可能参与细胞应激反应,但它并非该模型中顺铂耐药性的主要决定因素。这些发现凸显了卵巢癌药物耐药机制的复杂性,其中药物转运、DNA修复和细胞内解毒等多条通路可能并行作用。

OVCAR-4 已被纳入 NCI-60 癌症细胞系库,并被用于高通量表型分析研究。 基于荧光的筛选方法表明,当暴露于多种荧光探针时,OVCAR-4 表现出独特的细胞内染色模式和强度动力学,使其能够与其他卵巢癌细胞系一同进行分类。这些表型特征反映了潜在的生化及形态学特征,支持将 OVCAR-4 应用于系统生物学、药物筛选及癌细胞谱系鉴定研究。

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

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。
