01General information

Description

SK-NEP-1 是一种人体细胞系,最初来源于肾母细胞瘤,又称威尔姆斯肿瘤,是一种常见的小儿肾脏恶性肿瘤。这种细胞系被广泛用于临床前研究,以研究肾母细胞瘤的生物学特性,并评估治疗威尔姆斯肿瘤的新疗法。然而,后来的分子特征研究发现,SK-NEP-1 表达的 EWS-FLI1 融合基因是尤文肉瘤的特征,这表明该细胞系更能代表尤文家族肿瘤,而不是威尔姆斯肿瘤。这一发现对于解释过去利用 SK-NEP-1 进行的研究具有重要意义,因为它的生物学特征更接近于尤文肉瘤,而不是无弹性威尔姆斯肿瘤。

涉及 SK-NEP-1 的研究表明,它对长春新碱等化疗药物有反应,长春新碱可抑制微管聚合,导致 G2/M 期停滞和细胞凋亡。此外,使用穿心莲内酯等天然化合物的联合疗法显示出协同效应,主要通过 PI3K-AKT-p53 信号通路增加长春新碱对 SK-NEP-1 细胞的细胞毒性。研究表明,这种联合疗法可在体外和体内诱导 SK-NEP-1 细胞凋亡,因此是治疗具有 SK-NEP-1 相同分子特征的肿瘤的一种很有前景的方法。

因此,SK-NEP-1 是研究小儿肾癌和尤文肉瘤的分子基础以及评估旨在改善这些癌症类型治疗效果的药物组合有效性的重要模型。将其用于研究有助于了解药物诱导的细胞凋亡以及在癌症治疗中靶向 PI3K-AKT-p53 等特定信号通路的潜力。

06Handling and culture

Culture medium
McCoys 5a,w:3.0 克/升葡萄糖,w:稳定谷氨酰胺,w:2.0 毫摩尔丙酮酸钠,w:2.2 克/升 NaHCO3(Cytion 文章编号 820200a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Subculturing
通过定期添加或更换培养基来维持细胞培养。初始培养时细胞密度应为5×10⁵个细胞/毫升,并保持细胞浓度在3×10⁵至1×10⁶个细胞/毫升范围内以获得最佳生长效果。
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。
