01General information

Description

IOSE-80细胞系是一种源自正常人类卵巢表面上皮的非致瘤性细胞系。在卵巢癌研究中,它作为关键对照,为比较癌细胞的行为提供了基准。 IOSE-80细胞已被用于探索正常卵巢组织与癌变卵巢组织中基因差异表达的研究。例如,将IOSE-80与SKOV-3和COC1等卵巢癌细胞系进行比较的研究发现,癌细胞中与免疫和铁死亡相关的特定基因显著上调,从而显示出截然不同的分子特征。

IOSE-80细胞的一个显著特征是其对各种治疗和实验条件的反应,这些实验旨在阐明癌细胞增殖和耐药的机制。这些细胞已被用作对照组,以评估化合物的细胞毒性,并评估药物选择性抗癌作用。 例如,研究表明,如山奈酚等黄酮类化合物虽能抑制卵巢癌细胞系的增殖并诱导其凋亡,但对IOSE-80细胞却未产生显著的细胞毒性作用,这表明IOSE-80细胞系具有非癌性特征和较强的抗逆性。

总体而言,IOSE-80是研究健康卵巢上皮细胞基线行为的宝贵模型,并作为理解导致卵巢癌恶变的变化的比较参考。这使其成为新型治疗方法研究、药物筛选以及卵巢癌发展分子机制研究中不可或缺的一部分。

05Handling and culture

Culture medium
RPMI 1640,含 2.1 mM 稳定型谷氨酰胺,含 2.0 g/L NaHCO₃ 的培养基(Cytion 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
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。

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。
