01General information

Description

SNU-761细胞系是一种源自成年患者的人类肝细胞癌(HCC)模型。作为“癌症细胞系百科全书”(CCLE)和“肝癌模型库”(LIMORE)计划的一部分,SNU-761已在多个分子层面进行了广泛的特征分析。 该细胞系已被用于探索原发性肝癌典型的遗传和转录组异质性,包括与乙型肝炎病毒(HBV)感染相关的异质性——这种感染在许多东亚HCC病例中十分普遍。 基因组分析表明,包括 SNU-761 在内的 LIMORE 模型通常保留了原发肿瘤的突变和拷贝数变异特征,其中包括 TP53、CTNNB1 和 FGF19 等关键致癌驱动基因的变异。

SNU-761 以及 LIMORE 资源库中的其他肝癌模型,已针对广泛的化疗药物和靶向药物进行了高通量药物敏感性筛选。这些药物基因组学数据集使研究人员能够识别潜在的疗效预测生物标志物,例如与肝癌常见突变相关的基因-药物关联及合成致死性。 此外,通过比较转录组和表观遗传学数据(如DNA甲基化和组蛋白修饰模式),有助于将SNU-761归类于肝癌亚型,并评估其功能特征,包括侵袭性及对通路特异性抑制剂的反应。这种全面的特征分析使SNU-761成为研究HBV相关HCC及评估个性化治疗策略的宝贵模型。

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。
