01General information

Description

TE10细胞系属于TE系列,该系列是日本建立的一组食管癌模型,具体源自一例分化良好的食管鳞状细胞癌。 TE10细胞以其上皮样形态和单层培养特性而著称。这些细胞源自未曾接受过放射治疗的原发病灶,因此能够代表未经治疗的肿瘤生物学特征。

TE10 表现出与食管癌进展相关的若干关键遗传改变。其中包括 c-erbB 基因的扩增和过表达、int-2 和 hst-1 原癌基因的共扩增,以及 TGF-α 和 EGF-R 等生长因子的调节失衡。 这些分子特征使TE10成为研究肿瘤生长相关通路(如表皮生长因子受体(EGFR)信号轴)的宝贵模型。此外,该细胞系还被用于研究对靶向治疗和化疗药物的反应,从而阐明药物耐药性的机制。

由于TE10细胞具有在软琼脂中形成集落以及表现出锚定独立生长的能力,因此也常被用于侵袭和迁移实验。这些特性凸显了其在探索转移分子驱动因素方面的实用价值。 该细胞系在肿瘤生物学和药理学实验中表现稳定,使其成为转化癌症研究的重要工具,特别是在针对食管鳞状细胞癌的治疗策略开发方面。

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。
