01General information

Description

SNU-C1细胞系是由韩国成人患者腹水建立的人类结直肠癌模型。该细胞源自结肠中分化腺癌,属于由结直肠癌患者衍生的SNU系列细胞系之一。 由于其分子特征及体外培养条件下相对稳定的生长特性,SNU-C1已被广泛应用于胃肠道癌症生物学和药物基因组学研究。

基因组学上,SNU-C1呈现微卫星不稳定性(MSI)特征——该表型常见于因DNA错配修复(MMR)系统缺陷导致的特定结直肠癌亚型。这种MSI状态对药物敏感性和基因组不稳定性具有重要影响。 尽管携带WNT和p53等关键通路突变等多重结直肠癌常见遗传改变,SNU-C1仍展现出独特的蛋白质组学和转录组学特征,使其适用于分子亚型分类及高通量药物反应分析。 该细胞系已被纳入癌症细胞系百科全书(CCLE)等大型数据库,其中蛋白质组学定量分析证实其表达模式与上皮起源及MSI表型相符。这些特性使SNU-C1成为研究MSI高表达结直肠癌治疗反应及解析结直肠肿瘤分子多样性的宝贵资源。

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。
