01General information

Description

OVCAR-8 是一种人类卵巢癌细胞系,由一名晚期卵巢腺癌患者建立。该细胞系对患者治疗期间大剂量使用的顺铂和卡铂具有明显的抗药性,这一点尤为突出。OVCAR-8 被广泛用于研究卵巢癌的化疗耐药性机制,以及开发克服铂类化疗耐药性的策略。

OVCAR-8 细胞呈上皮形态,在培养过程中粘附生长。该细胞系具有与高级别卵巢癌相关的分子和表型特征,包括 DNA 损伤修复机制和其他有助于肿瘤在化疗压力下存活的途径的改变。与其他一些卵巢癌细胞系不同,OVCAR-8 没有检测到金属硫蛋白的表达。不过,该细胞系对镉和其他药物具有交叉耐药性,这表明存在其他耐药机制,如谷胱甘肽水平升高和DNA修复能力增强。

在临床前研究中,OVCAR-8 是筛选化疗药物、评估靶向疗法和研究化疗耐药性生物学的重要工具。研究人员利用这种细胞系探索药物组合,旨在使抗药性肿瘤对标准治疗敏感。此外,OVCAR-8 还能让人们深入了解卵巢癌细胞的基因和分子适应性,这些适应性是卵巢癌细胞在积极化疗方案下仍能存活和持续存在的基础。它的临床相关性和耐药性特征使其成为推动卵巢癌研究和治疗开发的重要资源。

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。
