01General information

Description

SF126 细胞系是一种人类胶质母细胞瘤细胞系,广泛用于脑肿瘤研究,特别是用于探索胶质母细胞瘤的分子机制及其对各种治疗方法的反应。SF126 细胞来源于一名多形性胶质母细胞瘤患者,具有典型的胶质母细胞瘤的侵袭性生长和侵袭行为,是研究治疗策略和了解肿瘤生物学的重要模型。SF126 的一个显著特点是可用于探索细胞凋亡(程序性细胞死亡)和自噬,因为这些过程是癌细胞存活和抵抗治疗的核心。

人们对 SF126 与 p53 的相互作用进行了广泛的研究,p53 是一种在癌症中经常发生突变的肿瘤抑制基因。在 SF126 中,研究人员调查了野生型和突变型 p53 对细胞死亡机制的影响。研究发现,p53 可诱导细胞凋亡和自噬,而自噬细胞死亡在 p53 依赖性细胞死亡中起着重要作用。这对以自噬途径为靶点的疗法有一定影响,可提高旨在诱导肿瘤细胞死亡的疗法的疗效。此外,研究表明,操纵自噬可以影响肿瘤对 p53 激活的整体反应,为胶质母细胞瘤的治疗提供了潜在的治疗角度。

对 SF126 的进一步研究探讨了它与β-内啡肽等阿片肽的结合特性,揭示了这些分子的特定结合位点。这使人们深入了解了胶质母细胞瘤细胞如何与大脑中的内源性激素和信号分子相互作用,进一步凸显了胶质母细胞瘤生物学的复杂性和潜在的新型治疗靶点。

06Handling 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.

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。
