01General information
- Description
HEI-OC1 细胞系来自转基因不死鼠的耳蜗,是研究听觉细胞生物学的多功能模型,特别是在耳毒性和保护机制方面。HEI-OC1 细胞是有条件永生的细胞,具有柯蒂器官感觉细胞和支持细胞的特征。这些细胞表达各种耳蜗毛细胞标记,包括预蛋白、肌球蛋白 7a 和钙巴林蛋白。作为一种体外模型,HEI-OC1 已被用于研究细胞对氨基糖苷类和顺铂等耳毒性药物的反应,众所周知,这些药物会通过细胞凋亡、ROS 积累和线粒体功能障碍诱发听力损失。
HEI-OC1 细胞在探索针对耳毒性损伤的保护性策略方面表现出了实用性。例如,研究表明溶血磷脂酸(LPA)可以通过减少细胞凋亡、过度自噬和 ROS 积累来减轻顺铂的细胞毒性作用。此外,研究还发现,抑制铁凋亡(一种依赖铁的细胞死亡)可通过保护线粒体功能来保护 HEI-OC1 细胞免受顺铂诱导的损伤。还观察到应用糖皮质激素(如地塞米松)可通过调节 PERK-CHOP 通路保护 HEI-OC1 细胞免受内质网应激诱导的细胞凋亡。这些发现支持将 HEI-OC1 细胞作为筛选耳毒性药物和研究耳保护干预措施的宝贵模型。

- Culture medium
- DMEM,w:4.5 克/升葡萄糖,w:4 毫摩尔 L-谷氨酰胺,w:3.7 克/升 NaHCO3,w:1.0 毫摩尔丙酮酸钠(Cytion 编号 820300a)。
- Incubation atmosphere
37°C, 5%CO2, 加湿环境。
- Supplements
- 在培养基中添加 10% FBS
- Dissociation reagent
- Accutase
- Subculturing
- 去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 TrypLE Express 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混匀细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。
- 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.
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。

09Legal 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。
