01General information

Description

HK-2 细胞系是从正常成人肾脏组织中提取的特性良好的人类近端肾小管上皮细胞系。这些细胞表现出典型的上皮形态,并保留了近端肾小管细胞的许多生化和功能特性,是研究肾脏生理和病理生理学的宝贵模型。HK-2 细胞以其主动转运能力和刷状缘酶活性而著称,这对它们在肾脏重吸收过程中的作用至关重要。

HK-2 细胞表达一系列转运体和受体,包括葡萄糖、氨基酸和各种离子的转运体和受体,这反映了它们在肾过滤和重吸收过程中的作用。它们对激素的调节也有反应,如甲状旁腺激素和醛固酮,这些激素会影响它们的转运活动。由于这些特点,HK-2 细胞被广泛用于肾毒性研究、药物筛选以及急性肾损伤和慢性肾病等肾脏疾病的研究。

此外,HK-2 细胞还被用于研究肾细胞癌和其他与肾脏相关的癌症。它们提供了一个可靠的体外系统,用于检查细胞对有毒制剂、氧化应激和缺氧的反应。研究人员还利用 HK-2 细胞探索肾脏纤维化和炎症的分子机制。总之,HK-2 细胞系是肾脏研究的重要工具,它能帮助人们深入了解肾脏的正常功能和疾病的发病机制。

06Handling and culture

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
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。
Fluid renewal
每周 2 至 3 次
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。
