01General information

Description

LMH 细胞来源于莱霍恩雄性肝癌,是一种广泛应用于生物学研究的多功能细胞系。1981 年,北川智之在日本东京癌症研究所建立了 LMH 细胞系。这些细胞具有上皮表型,特别适用于研究家禽胃肠道中宿主与病原体的相互作用。

LMH 细胞具有粘附性,呈现树突状形态。它们表达葡萄糖-6-磷酸酶和微弱的管状 ATP 酶活性。这些细胞具有三倍体核型和六条标记染色体,显示出明显的遗传特征。
值得注意的是,LMH 细胞在转染病毒构建体时能有效支持鸭乙型肝炎病毒(DHBV)DNA 的合成。这使它们成为病毒学研究的宝贵工具,特别是在与家禽相关的病毒感染方面。
LMH 细胞的产生涉及通过长期使用二乙基亚硝胺诱导家禽肝脏中的肿瘤结节。这些细胞还经过化学转化,实现了永生化和在培养物中持续繁殖。

就致瘤性而言,LMH 细胞能够在无胸腺裸鼠体内形成肿瘤。这一特性使其成为研究肝细胞癌的重要模型。LMH 细胞能表达雌激素受体,并能被诱导表达肝脏特异性载脂蛋白 II(apoII)基因。这表明它们参与了雌激素信号通路和脂质代谢。要培养 LMH 细胞,必须在组织培养容器上预先涂上胶原蛋白。这可确保细胞的正常粘附和生长。

Subculturing
LMH 细胞能更好地附着在预先涂有胶原蛋白的组织培养容器上。去除培养基,用不含钙和镁的 PBS 冲洗附着的细胞(T25 细胞培养皿用 3-5 毫升 PBS,T75 细胞培养皿用 5-10 毫升)。加入 Accutase(每个 T25 细胞培养瓶 1-2 毫升,每个 T75 细胞培养瓶 2.5 毫升),细胞片必须完全覆盖。在环境温度下孵育 8-10 分钟。用培养基(10 毫升)小心重悬细胞,300 克离心 3 分钟,用新鲜培养基重悬细胞,然后分装到装有新鲜培养基的新培养瓶中。

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。
