01General information

Description

ASB-xIV 细胞来源于雌性 Balb/c 小鼠,与温石棉在小鼠肺细胞中诱发的大细胞癌非常相似。这些细胞具有上皮形态的单层粘附性,是原发性鳞状细胞癌(PSCC)研究的典范模型。它们的结构和功能特点使其特别适合于详细研究 PSCC 的细胞过程和病理机制。

ASB-xIV 细胞系的特点是 "发炎 "或 "发热 "肿瘤,这表明其免疫细胞浸润程度较高,因此对免疫疗法的反应更为敏感。这种敏感性是使用 ASB-xIV 细胞评估免疫检查点疗法(ICT)疗效的关键。这些细胞已显示出对此类疗法的明显反应性,这使它们在以免疫疗法疗效为重点的肿瘤研究中显得弥足珍贵。此外,虽然维甲酸能有效抑制这些细胞在小鼠移植癌中的生长,但维生素 C 却未能产生类似的效果。尽管 ASB-xIV 细胞的倍增时间约为 70 小时,但它们仍能保持强劲稳定的生长,这对于建立实验重现性所需的一致可靠的体外培养至关重要。

06Handling and culture

Culture medium
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 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
建议的接种密度为1×10⁴个细胞/平方厘米。
Fluid renewal
每 3 至 5 天
Post-thaw recovery
让细胞粘附至少 24 到 48 小时。
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。
