01General information

Description

OCUM-1 是一种源自一名低分化胃腺癌患者的人胃癌细胞系。该细胞系在癌症研究中被广泛用于研究胃癌的侵袭性,尤其是分化程度较低的胃癌。 OCUM-1 作为一种可靠的体外模型,用于研究胃腺癌的肿瘤生物学、转移机制及治疗反应,而胃腺癌仍是全球癌症相关死亡的主要原因之一。

OCUM-1 细胞呈现上皮形态,并在标准培养条件下具有粘附性。其具有低分化胃癌的典型特征,包括高增殖能力、侵袭周围组织的能力,以及驱动肿瘤进展的分子改变。 研究人员经常使用 OCUM-1 来研究 Wnt/β-catenin、PI3K/AKT 以及与上皮-间质转化(EMT)相关的机制等信号传导通路,这些通路在胃腺癌中往往失调,并促使其发生转移。 此外,该细胞系还为评估与低分化肿瘤相关的遗传和表观遗传变化提供了平台。

在临床前研究中,OCUM-1对于药物筛选以及针对侵袭性胃癌亚型的靶向治疗研发具有特别重要的价值。该细胞系常被用于评估化疗药物、小分子抑制剂和联合疗法的疗效,以及探索化疗耐药的机制。 此外,OCUM-1还被用于研究肿瘤微环境相互作用以及腹膜播散的分子驱动因素——腹膜播散是晚期胃癌中一种常见且难以应对的并发症。总体而言,OCUM-1仍是推动胃癌研究和发现新型治疗方法的关键资源。

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。
