01General information

Description

SNU-423 细胞系是从一名韩国成年患者身上建立的人类肝细胞癌(HCC)模型。它是源自原发性肝肿瘤的八种 HCC 细胞系之一,具有形态学、遗传学和病毒学特性。SNU-423 具有底物粘附性,并保持了原始肿瘤的许多组织学特征,与肝细胞衍生上皮形态一致。它表现出非整倍体性,其模式染色体数显示出染色体不稳定性,这在 HCC 衍生系中很常见。

在分子水平上,SNU-423 的显著特点是在其基因组中整合了乙型肝炎病毒(HBV)DNA,这也是该系列中所有细胞系的共同特征,反映了东亚地区 HBV 相关肝癌的高发病率。虽然该系列中的一些细胞系表达 HBV 转录本,如 HBVx,但 SNU-423 中的特异性转录本表达未见报道。此外,SNU-423 在 RNA 或蛋白水平上都不表达甲胎蛋白(AFP),这使其与缺乏甲胎蛋白分泌的 HCC 亚群相一致。它已被用于药物基因组学筛选,如 LIMORE(肝癌模型库),有助于了解肝癌中基因与药物的关联,包括可能与 HBV 状态或不同致癌基因改变有关的药物反应变异。

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。
