01General information

Description

由于与人类乳腺癌高度相似,4T1 小鼠乳腺癌细胞系是癌症研究中广泛使用的模型。4T1 细胞系来源于 BALB/c 小鼠,其肿瘤生长和转移扩散与人类晚期乳腺癌的行为非常相似。4T1 细胞系是研究乳腺癌进展和转移(包括骨转移和乳腺癌转移)的宝贵工具。当把 4T1 细胞注射到 BALB/c 小鼠体内时,它们会自发产生高度转移性肿瘤,这些肿瘤会扩散到肺、肝、淋巴结和骨等多个器官,而原发肿瘤则继续在原位生长。这种 4T1 合成模型特别适用于骨转移和转移表型的研究。

4T1 细胞的用途还包括生物发光成像、组织学分析等技术,以及使用分子标记追踪转移性疾病的扩散和影响。在流式细胞术等技术的帮助下,这种方法可以分析肿瘤细胞及其受体表达,从而检查原发性肿瘤向远处器官的自发转移。可成像的 4T1 模型使生物光子成像技术得以在动物模型中追踪体内肿瘤的生长和转移,促进了对目标器官和肿瘤病灶中转移细胞的研究。

小鼠 4T1 乳腺肿瘤细胞系的免疫能力强,有助于研究免疫系统和免疫在转移中的作用,以及癌症的免疫疗法。此外,4T1 合成肿瘤模型还有助于omics特性分析和融合基因检测。

总之,4T1 乳腺癌细胞系是研究乳腺肿瘤生物学、肿瘤转移以及开发小鼠和人类新疗法的多功能工具。

05Handling and culture

Culture medium
RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
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。
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.

06Quality 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。
