01General information

Description

SK-N-AS 细胞系来源于人类儿童的神经母细胞瘤,被广泛用于神经肿瘤学研究。神经母细胞瘤是一种产生于神经嵴细胞的癌症,主要影响儿童。SK-N-AS 细胞为研究神经母细胞瘤的生物学和治疗提供了一个宝贵的模型,特别是在了解驱动肿瘤发生和发展的分子机制方面。这种细胞系的特点是处于相对未分化状态,因此有助于研究神经元分化和恶性肿瘤的相关途径。

SK-N-AS 细胞呈现粘附生长模式,具有神经母细胞形态。它们表达与神经嵴细胞和神经母细胞瘤相关的各种标记物,包括神经元特异性烯醇化酶(NSE)和嗜铬粒蛋白A。研究人员利用SK-N-AS细胞研究与神经母细胞瘤相关的遗传和表观遗传学变化,如MYCN扩增和ALK突变。这些细胞还被用于新型化疗药物和靶向疗法的高通量药物筛选和临床前测试。此外,SK-N-AS 细胞还用于研究传统疗法的抗药性机制,并开发克服这种抗药性的策略。SK-N-AS细胞与神经母细胞瘤研究的相关性突出表明,它们在促进我们对这种侵袭性儿童癌症的了解和改善受影响患者的治疗方法方面具有重要意义。

06Handling and culture

Culture medium
DMEM,w:4.5 克/升葡萄糖,w:4 毫摩尔 L-谷氨酰胺,w:3.7 克/升 NaHCO3,w:1.0 毫摩尔丙酮酸钠(Cytion 编号 820300a)。
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。
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
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。
