01General information

Description

OE19是一种源自巴雷特食管相关腺癌患者原发肿瘤的人类食管腺癌细胞系。该细胞系被广泛应用于食管癌研究,尤其适用于探究巴雷特食管进展过程中的肿瘤发生机制。 OE19可作为研究上消化道恶性肿瘤中腺癌发展、治疗反应及耐药机制的分子机制模型。

OE19细胞呈现上皮形态,可在标准培养条件下附着生长。其基因组改变及分子特征具有食管腺癌典型性,包括HER2/neu(ERBB2)过表达——该标志物既是侵袭性肿瘤行为特征,也是临床治疗的重要靶点。这使得OE19特别适用于测试HER2靶向疗法,如单克隆抗体和酪氨酸激酶抑制剂。 此外,OE19细胞常用于探索癌症进展的关键信号通路,包括MAPK/ERK和PI3K/AKT通路,以及免疫逃逸机制和肿瘤微环境相互作用机制。

在临床前研究中,OE19细胞系可有效评估化疗药物、靶向治疗及旨在克服耐药性的新型联合疗法。该细胞系还被用于异种移植模型,以评估肿瘤生长及体内治疗效果。其分子特征与巴雷特食管相关腺癌的关联性,使OE19成为推进该复杂恶性肿瘤研究与治疗的重要资源。

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。
