01General information
- Description
MET-5A 细胞系来源于人类成年人的胸膜间皮细胞,常用于与间皮瘤有关的研究,间皮瘤是一种影响肺部、腹部和心脏间皮内膜的癌症。这些细胞对于研究间皮瘤的生物学、发病机制和治疗至关重要,尤其是在了解石棉暴露等环境因素如何导致这种癌症的发生方面。MET-5A 细胞还用于探索细胞转化、肿瘤进展和细胞对各种化疗药物的反应机制。
MET-5A 细胞具有典型的上皮形态,并保留了正常间皮细胞的特征,包括表达细胞角蛋白和波形蛋白等间皮细胞标志物。这些细胞对炎症刺激反应灵敏,可用于研究间皮瘤发病过程中的炎症过程。研究人员利用 MET-5A 细胞研究与间皮瘤相关的遗传和分子改变,并测试潜在治疗化合物的疗效和毒性。MET-5A细胞在间皮细胞生物学建模中的相关性及其在间皮瘤研究中的作用,使其成为促进我们了解和治疗这种侵袭性癌症的重要工具。

06Handling and culture
- Culture medium
- 培养基 199,w:1.5 克/升 NaHCO3
- Incubation atmosphere
37°C, 5%CO2, 加湿环境。
- Supplements
在培养基中加入15% FBS、15 mM HEPES、1% ITS+
- 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
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。
