01General information

Description

ACHN细胞系源自一名22岁白人男性患者的恶性胸腔积液,该患者患有广泛转移性肾腺癌。1979年11月,通过将癌细胞直接接种至含10%胎牛血清的Eagle's MEM培养基培养瓶中,成功建立该细胞系。 在150天内,细胞经体外培养与传代维持。随后将细胞皮下接种至裸鼠体内,四周内形成可触及的局部侵袭性肿瘤。该细胞系具有致瘤性,接种10⁷个细胞的裸鼠(5/5)100%发生肿瘤,且肿瘤在21天内形成。

ACHN细胞具有粘附生长模式,并表达特定同工酶,包括G6PD(B型)。 该细胞系对人干扰素及干扰素诱导剂的响应特性尤为显著,使其在抗增殖研究中具有重要价值。原始ACHN细胞及裸鼠肿瘤中分离的细胞均表现出人干扰素抑制增殖的特性,凸显其在探索干扰素类肾癌治疗疗效研究中的潜在应用价值。

ACHN细胞系是癌症研究的宝贵工具,尤其在肾腺癌领域。它作为研究肿瘤形成能力、转移行为以及干扰素对癌细胞增殖影响的重要模型,其体内成瘤能力和对干扰素治疗的响应特性,为开发和测试针对肾细胞癌的新疗法提供了坚实平台。

06Handling and culture

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
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/cm²将在4天内形成融合的单层细胞。
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
  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。
