01General information

Description

HuH-1细胞系源自人肝细胞癌(HCC),在肝癌研究中得到广泛应用。该细胞系已显示出能够产生和分泌多种肝脏特异性蛋白的能力,包括通常存在于人血浆中的蛋白。 值得注意的是,与其他人类肝癌细胞系一样,HuH-1细胞在体外培养中能够表达并释放乙型肝炎表面抗原(HBsAg),为研究乙型肝炎病毒相关肝细胞癌的发病机制提供了模型。 在培养中产生HBsAg的能力表明,HuH-1细胞保留了与体内肝细胞相似的分化功能。

HuH-1细胞在研究肝癌的调控机制方面也起着关键作用,特别是涉及微RNA及其靶基因的机制。例如,研究表明,miR-182的上调可通过下调转移抑制因子1(MTSS1)来增强HCC细胞(包括HuH-1)的转移潜能。 这种下调会促进侵袭性行为,并凸显了特定微RNA在调节基因表达和影响癌细胞行为中的作用。这些见解对于理解HCC的进展以及制定靶向治疗策略具有重要价值。

HuH-1细胞系的应用范围还延伸至肿瘤微环境及其与病毒因子相互作用的研究,使其成为探索致癌基因、抑癌基因和病毒蛋白之间复杂关系的理想模型。 该细胞系有助于阐明肝癌发生的多重途径,并推动针对肝癌分子机制的个性化抗癌疗法的研发。

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
  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。
