01General information

Description

BT-549 细胞是一种人类乳腺癌细胞系,来源于一名 72 岁白种女性乳腺导管癌患者的乳腺组织。它们通常用于癌症研究,以研究乳腺癌的生物学和治疗,尤其是缺乏雌激素受体、孕激素受体和 HER2 表达的三阴性亚型乳腺癌。

BT-549 细胞具有上皮形态特征,并以其高度侵袭性而闻名,因此是研究转移和肿瘤侵袭的重要模型。它们表现出一些独特的特征,包括细胞质中存在脂滴以及粘蛋白-1 蛋白的大量表达。这些细胞还表达与乳腺癌病理相关的各种癌基因和肿瘤抑制基因,如 TP53 和 RB1。

BT-549 细胞系雌激素受体阴性,孕激素受体阴性,不扩增 HER2,因此被归类为三阴性乳腺癌(TNBC)亚型。由于这种分类,BT-549 细胞特别适用于研究 TNBC 的独特进展机制和治疗反应,TNBC 以其侵袭性和缺乏靶向疗法而著称。

此外,BT-549 细胞还经常被用于耐药性研究以及测试新的化疗药物和靶向疗法,为管理和治疗侵袭性乳腺癌的潜在治疗策略提供见解。

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
1×10⁴个细胞/cm²将在约4天内形成融合细胞层
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。
