01General information

Description

NCH640 细胞系是一种胶质母细胞瘤干样细胞模型,用于探索肿瘤抗药性、压力下细胞存活和治疗反应的机制。胶质母细胞瘤是侵袭性最强的脑肿瘤之一,由于其抗药性和对恶劣微环境的适应性而难以治疗。NCH640 在 Neurobasal A 等专用培养基中培养,并添加 B27 等补充剂,其生长需要 EGF 和 FGF-2 等基本生长因子的支持。它经常与其他胶质瘤干细胞模型(如 NCH690 和 NCH644)一起用于研究这些生物现象。

对NCH640的研究主要集中在其抵抗机制上,尤其是在缺氧条件下。像 NCH640 这样的胶质瘤细胞显示出对代谢适应性的严重依赖,包括活性氧(ROS)调节的改变。研究表明,在 NCH640 和相关细胞系中靶向综合应激反应(ISR)等通路可提高它们对替莫唑胺等疗法的敏感性,而替莫唑胺是治疗胶质母细胞瘤的常用药物。这些发现对于制定新策略以克服胶质瘤干样细胞对标准治疗干预的固有抗药性非常重要。

05Handling and culture

Culture medium
DMEM:Ham's F12(1:1),w: 3.1 g/L 葡萄糖,w: 2.5 mM L-谷氨酰胺,w: 15 mM HEPES,w: 0.5 mM 丙酮酸钠,w: 1.2 g/L NaHCO3(Cytion 文章编号 820400a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中加入5 mg/L 肝素、20 ng/mL bFGF、20 微克/L EGF、 5 mg/L 胰岛素、100 mg/L 转铁蛋白、5.2 微克/L 亚硒酸钠、6.3 微克/L 黄体酮、161.1 微克/L 腐胺、50 mg/L 氢化可的松
Subculturing
对于球形培养物的亚培养,首先使用带有 1000 μl 滤芯的 Eppendorf 移液器,通过上下移液 5 到 10 次,机械地将球形培养物分离。然后,将混合物在室温下以 300g 离心 5 分钟,使细胞沉淀。弃去上清液,用新鲜培养液重悬细胞团。最后,将重新悬浮的细胞转移到新的培养容器中,以促进球形细胞的进一步形成。这种方法可确保球形体的有效分解,并为它们在新环境中继续生长做好准备。

Fluid renewal
每周 2 至 3 次
Post-thaw recovery
解冻后,让细胞从冷冻过程中恢复至少 24 到 48 小时。
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。
