01General information

Description

SCC-4 是一种人类舌鳞状细胞癌(SCC)细胞系,广泛用于癌症研究,以探索口腔癌的发展、细胞凋亡和对化疗药物的反应机制。口腔鳞状细胞癌是口腔常见的恶性肿瘤,通常与吸烟和饮酒等生活方式有关。SCC-4 细胞的特点是具有侵袭性,可用于体外模拟肿瘤行为和治疗耐药性。

利用 SCC-4 细胞进行的研究表明,大黄霉素、大黄素和小檗碱等几种化合物可通过内在(线粒体依赖)和外在(死亡受体介导)途径诱导细胞凋亡。大黄霉素通过内质网应激、ROS 生成和线粒体功能障碍,引发 caspase-8、-9 和-3 的活化,从而诱导 S 期细胞周期停滞和细胞凋亡。 同样,大黄素被证明可导致 G2/M 期细胞周期停滞,并通过破坏线粒体膜电位和促进细胞色素 c 释放来诱导细胞凋亡。小檗碱还能通过增强 ROS 生成、增加细胞内 Ca2+ 和降低线粒体膜电位,从而激活 caspase-9 和 caspase-3 通路,诱导 SCC-4 细胞凋亡。

这些研究结果表明,SCC-4 是研究潜在抗癌药物导致细胞凋亡的分子机制的有效模型,有助于深入了解针对口腔鳞状细胞癌的治疗策略。

突变:TP53,p.Pro151Ser(c.451C>T)

06Handling 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
在培养基中添加 10% FBS 和 400 纳克/毫升氢化可的松
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
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。
