01General information

Description

SK-N-LO 细胞系是一种人类神经母细胞瘤细胞系,用于研究神经母细胞瘤以及细胞凋亡机制和癌症信号通路。它也被归类为原始神经外胚层肿瘤(PNET)细胞系,携带尤文肉瘤家族肿瘤(ESFT)中常见的 EWS-FLI1 融合基因。这种融合基因来自染色体易位,在这些肿瘤细胞的致癌行为中起着关键作用。

SK-N-LO 细胞对某些针对致癌信号通路的抑制剂特别敏感。例如,GLI 抑制剂 GANT61 已被证明能诱导 SK-N-LO 细胞发生不依赖于 Caspase 的凋亡。GANT61 会破坏刺猬(Hh)信号通路中 GLI1 和 GLI2- 介导的转录,而这对该细胞系的细胞存活和增殖至关重要。经 GANT61 处理后,SK-N-LO 细胞表现出与凋亡相关的形态学变化,如染色质凝聚和核破碎。此外,GANT61 还会降低对细胞周期进展和存活非常重要的 GLI2 和 survivin 等蛋白质的表达,同时增加细胞周期蛋白依赖性激酶抑制剂 p21 的表达。

此外,SK-N-LO 细胞也被用来研究阿片受体信号转导。这些细胞经改造后可表达μ-阿片受体,是研究阿片诱导的镇痛与细胞内信号通路之间相互作用的宝贵模型。例如,研究表明吗啡可通过PI3Kγ途径刺激SK-N-LO细胞中的Akt磷酸化,而这一过程可由cAMP信号调节。这凸显了SK-N-LO细胞在探索癌症生物学和神经药理学方面的多功能性。

05Handling and culture

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
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。

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.

06Quality 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
作为冷冻保存培养基,我们使用 50% 基础培养基 + 40% FBS + 10% DMSO 或 CM-1(Cytion 目录号 800100),其中包括优化的渗透保护剂和代谢稳定剂,以促进恢复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。
