01General information

Description

SK-CO-1细胞系是一种源自腹水转移灶的人结直肠腺癌模型。该细胞系在癌症研究中被广泛用于探索结直肠癌(CRC)进展及对治疗干预反应的分子机制。 SK-CO-1细胞在培养中呈贴壁生长,其形态特征与上皮性肿瘤细胞一致。该细胞系已被纳入大规模基因组研究项目,例如“癌症细胞系百科全书”(CCLE),该项目提供了全面的遗传学、转录组学及药理学特征分析。

针对 SK-CO-1 的遗传学研究已鉴定出与结直肠癌发病机制密切相关的基因突变和拷贝数变异,包括 TP53、KRAS 和 APC 基因的改变。这些特征使其成为探索 WNT/β-catenin 信号传导等通路的宝贵模型,该通路在结直肠肿瘤发展中起着重要作用。 此外,药理学筛选揭示了该细胞系对化疗药物的差异性敏感性,有助于研究人员识别药物反应的潜在生物标志物。

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
Dissociation reagent
Accutase
Subculturing
倒出培养基,用0.25%胰蛋白酶、0.03% EDTA溶液冲洗。倒出溶液,再加入1至2毫升胰蛋白酶-EDTA溶液。将培养瓶置于室温(或37°C)下静置,直至细胞脱落。加入新鲜培养基,吸出细胞并转移至新的培养瓶中。
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。
