01General information

Description

SNU-368细胞系是一种人肝细胞癌(HCC)模型,源自一名54岁男性患者的原发性肿瘤。该细胞系属于由韩国患者建立的八种HCC细胞系组合的一部分,旨在反映肝癌多样化的分子和表型特征。 SNU-368细胞呈现多边形贴壁形态,并保留原发肿瘤的多种组织学特征,包括梁状和腺泡状排列结构,这些特征符合Edmondson分级II至IV级的分化程度。

遗传学上,SNU-368细胞携带整合型乙型肝炎病毒(HBV)DNA,并表达HBV转录本(包括HBx和preS/S)。这些特征使其成为研究HBV相关肝癌发生的重要模型。 SNU-368细胞同时表达转铁蛋白和胰岛素样生长因子II(IGF-II),但无论在RNA或蛋白质水平均不产生甲胎蛋白(AFP)。此类分子特征对于探索与病毒感染、生长因子信号传导及代谢改变相关的肝癌通路具有重要意义。

SNU-368细胞系已被应用于药物基因组学研究,尤其在肝癌模型库(LIMORE)中用于探究药物反应并识别靶向治疗的潜在生物标志物。该细胞系参与大规模基因组与转录组分析,彰显其在模拟原发性肝癌异质性方面的价值,使其成为研究肝癌分子机制及评估新型治疗药物的重要工具。

Subculturing
移去培养基,加入新的 0.25 % 胰蛋白酶 0.02 % EDTA 溶液,将培养瓶在 37''''C 下静置 3 至 5 分钟,加入培养基并收集细胞,将培养基转移到 15 毫升试管中,离心,吸出培养基,用培养基重悬细胞团并分配到培养瓶中。
Fluid renewal
每周 2 至 3 次
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。
