01General information
- Description
HEYA8细胞系是人类卵巢癌的一个特征明确的模型,最初是从一名乳头状囊腺癌患者体内建立的。该细胞系以其侵袭性生长和转移潜能而著称,常用于卵巢癌病理生理学及治疗研究。 HEYA8细胞因表达白细胞介素-8(IL-8)而受到广泛研究,IL-8是一种与癌症进展相关的趋化因子。IL-8作为一种自分泌生长因子,可促进细胞增殖、血管生成和肿瘤侵袭性。 值得注意的是,在 HEYA8 细胞中,高水平的 IL-8 表达与肿瘤生长加速及微血管密度增加呈正相关。通过 IL-8 载体进行的实验性转染表明,增强 IL-8 表达可显著促进肿瘤增殖,而中和抗体则能抑制这种生长。
HEYA8细胞还被用于研究卵巢癌对各种应激条件(如缺氧)的反应。 缺氧会通过涉及PI3K/Akt和p38 MAPK的信号通路,诱导这些细胞中IL-8的过表达。这些通路的激活通过AP-1和NF-κB等因子增强IL-8基因转录,从而促进肿瘤对低氧环境的适应,并维持其生存和转移能力。 因此,针对PI3K和p38 MAPK通路的抑制剂正被探索作为潜在策略,以缓解HEYA8细胞的侵袭性特征并减缓肿瘤进展。

- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
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.
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.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
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.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
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.
Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
05Quality 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。

07Legal and safety
- Safety precautions
- 计划将低温样品储存在液氮中以便将来解冻时,必须遵守严格的安全措施。在将冷冻样本移入或移出液氮罐时,必须穿戴适当的防护手套和防护服,并使用面罩或安全护目镜。这样做是为了降低在移出时因冷冻样品爆炸而造成伤害的风险,因为爆炸可能导致锋利的碎片飞溅。
