01General information

Description

SK-N-DZ细胞系是一种从神经母细胞瘤患儿的转移性骨髓中建立的人类神经母细胞瘤模型。 该细胞系属于SK-N系列神经母细胞瘤细胞系,具有神经嵴来源肿瘤细胞的特征。这些细胞在培养中呈贴壁生长,且含有少量侧群(SP)细胞,这表明存在具有高药物外排能力的类癌干细胞亚群。

SK-N-DZ细胞已被广泛用于研究,以了解遗传和表观遗传改变在神经母细胞瘤中的作用。该细胞系已被证实携带MYCN扩增和ALK基因突变,这两者均与高危神经母细胞瘤的侵袭性表型和不良预后有关。 此外,SK-N-DZ还被用于评估对维甲酸类和维生素E衍生物等药物的治疗反应。研究表明,与其他神经母细胞瘤细胞系不同,SK-N-DZ对13-顺式维甲酸具有独特的敏感性,在低浓度下即可引起显著的细胞裂解。

SK-N-DZ已被用于探索神经母细胞瘤分化和干细胞特性的实验。 该细胞系在特定处理条件下形成神经突延伸的能力,凸显了其在研究肿瘤分化和细胞可塑性方面的潜力。这些特征,加上其特征明确的遗传背景,使SK-N-DZ成为推进治疗策略和理解神经母细胞瘤分子机制的宝贵模型。

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。
