01General information

Description

KGN 细胞系是一种人类卵巢颗粒细胞肿瘤细胞系,来源于一名卵巢癌患者,经过永生化处理后用于各种研究。它保持了颗粒细胞的功能特性,包括激素合成,因此是研究颗粒细胞功能、激素调节和卵巢病理学的重要模型。KGN细胞已被用于研究多囊卵巢综合症(PCOS)等生殖和内分泌疾病的分子机制。KGN细胞对花生四烯酸(AA)等多不饱和脂肪酸的反应尤为突出,这种脂肪酸可诱导氧化应激(OS)并影响线粒体功能。

研究表明,KGN 细胞暴露于 AA 后,活性氧(ROS)和丙二醛(MDA)等氧化标志物水平升高,总抗氧化能力降低,线粒体活性受损,导致细胞凋亡。这一过程与生长分化因子 15(GDF15)的上调有关,GDF15 似乎对氧化应激诱导的细胞损伤起保护作用。此外,KGN 细胞对铁跃迁也很敏感,铁跃迁是一种以脂质过氧化和氧化应激为特征的铁依赖性细胞死亡形式。研究强调,通过转铁蛋白受体介导的铁吸收可促进 ROS 的产生,并促成这一途径。

此外,KGN细胞还被用于研究微RNA对细胞功能的影响,因为miR-93-5p已被确定为通过NF-κB信号通路促进细胞凋亡和铁凋亡的因子,将miRNA调控与多囊卵巢综合症中颗粒细胞功能障碍联系起来。这些功能使KGN细胞成为促进对卵巢病理生理学的了解和探索潜在治疗靶点的重要模型。

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 Accutase 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 毫升培养基轻轻混合细胞使其重悬,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
  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。
