01General information

Description

SW626系人卵巢癌细胞系,源自一名患有卵巢浆液性囊腺癌的成年患者。该细胞系已被广泛用作上皮性卵巢癌(EOC)模型,尤其适用于研究高级别浆液性癌的肿瘤生物学特性、药物反应及分子异质性。 组织学上,SW626细胞系保留了与其浆液性腺癌起源相符的特征,当移植到免疫缺陷小鼠体内时表现出肿瘤形成能力,可产生再现原发肿瘤特征的实体瘤。

SW626的基因组分析揭示了卵巢癌中常见的突变模式,包括TP53和PI3K/AKT等关键调控通路的破坏。分子研究表明该细胞系携带代表性高级别浆液性卵巢癌的染色体异常及基因表达模式,使其成为探究致癌信号通路、治疗靶点及耐药机制的理想模型。 该细胞系已被纳入大规模癌症基因组学项目,在药物筛选平台及与其他卵巢癌模型的比较研究中发挥重要作用,有助于界定分子亚型并为精准肿瘤学策略提供依据。

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。
