01General information
- Description
MNNG/HOS Cl #5细胞系[R-1059-D]源自人骨肉瘤细胞系HOS,通过在体外以0.01微克/毫升浓度的N-甲基-N'-硝基-N-亚硝基胍(MNNG)进行转化获得。 该化合物为强致癌物,转化后呈现显著致瘤特性:裸鼠皮下接种10⁷个细胞后,21天内100%发生肿瘤。观察发现这些肿瘤为低分化肉瘤或骨肉瘤。 该细胞系最初建立于一名13岁白人女性骨肉瘤患者,具有粘附生长特性。
功能上,MNNG/HOS Cl #5细胞在软琼脂培养中表现出高饱和密度与高铺板效率,反映其增强的锚定独立生长能力——这是恶性转化的标志性特征。此外,该细胞系具有显著纤溶活性,该特性与增强的致瘤潜力相关。 与未处理的HOS细胞相比,经MNNG处理的细胞在软琼脂中具有更强的细胞聚合特性和更高的集落形成倾向,这与其肿瘤形成能力相关。实验表明,MNNG转化细胞在裸鼠和仓鼠体内均能形成肿瘤,且细胞形态与亲本HOS细胞系相似;而在相同条件下,未处理细胞不具肿瘤形成能力。
该细胞系在研究癌症进展和肿瘤生物学(特别是骨肉瘤)方面具有重要价值,因其提供了化学诱导转化的模型。这些细胞能在免疫缺陷环境(如裸鼠)中生长,使其成为临床前癌症研究的宝贵工具,可用于探究肿瘤发生机制并测试潜在治疗干预措施。

- 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 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。
- Seeding density
- 1 × 10⁴ 个细胞/平方厘米
- Fluid renewal
- 每周 2 至 3 次
- Post-thaw recovery
- 解冻后,将细胞以5×10⁴个细胞/平方厘米的密度接种于培养皿中,使细胞从冷冻过程中恢复并至少贴壁24小时。
- 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。
