01General information

Description

EFO-27细胞系是一种源自中度分化浆液性乳头状腺癌的人卵巢癌模型。该细胞系是从一名晚期卵巢癌患者的实性大网膜转移灶中建立的。EFO-27属于一系列源自卵巢肿瘤的细胞系,这些细胞系旨在探索激素对卵巢癌细胞增殖的调控作用。 据报道,在早期传代阶段,EFO-27 呈非整倍体,其模态染色体数超过 100,表明其具有高度的染色体不稳定性,这是高分化浆液性卵巢癌的常见特征。

EFO-27 细胞在体外表现出上皮样形态,并在单层培养中形成穹顶状的多细胞结构,这种表型有时与主动离子转运和紧密连接的形成有关。 在无血清培养基中,EFO-27 的增殖受到促性腺激素(特别是人绒毛膜促性腺激素 (hCG) 和卵泡刺激素 (FSH))的刺激,这表明这些细胞保留了功能性的激素受体信号传导通路。 这种反应性突显了促性腺激素信号传导在促进卵巢癌生长和进展中的潜在作用,并支持将 EFO-27 作为研究卵巢癌生物学中激素驱动机制的相关模型。

EFO-27 还被纳入了主要的多组学数据集,例如癌症细胞系百科全书 (CCLE) 和 COSMIC,其中其基因组特征有助于药物敏感性图谱绘制和肿瘤亚型分类。这些数据集提供了更多层面的信息,包括基因表达、拷贝数变异和突变图谱,使 EFO-27 成为卵巢癌临床前研究中一个特征明确的资源。

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。
