01General information

Description

SK-BR-3 细胞是从一名 43 岁女性转移性乳腺癌患者的胸腔积液中分离出来的人类乳腺癌细胞系。SKBR3 细胞建立于 20 世纪 70 年代初,因其过度表达人表皮生长因子受体 2(HER2)而闻名,HER2 是一种受体酪氨酸激酶,在某些类型乳腺癌的发病和发展过程中起着至关重要的作用。

该细胞系具有乳腺癌常见的基因畸变特征,包括 HER2 基因的扩增和 p53 抑癌基因的突变。HER2在SK-BR-3细胞中的过度表达使其成为研究HER2阳性乳腺癌(具有侵袭性生长和预后不良的特点)和HER2靶向疗法的重要模型。SK-BR-3细胞在曲妥珠单抗(赫赛汀)的研究中发挥了重要作用,曲妥珠单抗是一种抗HER2的单克隆抗体,已成为治疗HER2阳性乳腺癌的基石。

SK-BR-3 细胞具有强大的体外生长速度,已被用于各种实验装置,包括细胞信号传导、耐药性、细胞凋亡和癌细胞周期研究。这些细胞也是生产单克隆抗体和研究乳腺癌细胞免疫反应的关键资源。

总之,SK-BR-3 细胞系是乳腺癌研究中不可或缺的工具,它提供了对 HER2 阳性肿瘤生物学的深刻见解,促进了靶向疗法的开发,大大改善了这种具有挑战性的癌症患者的前景。

06Handling and culture

Culture medium
McCoys 5a,w:3.0 克/升葡萄糖,w:稳定谷氨酰胺,w:2.0 毫摩尔丙酮酸钠,w:2.2 克/升 NaHCO3(Cytion 文章编号 820200a)。
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
从冷冻管中启动培养,细胞密度为3×10⁴个细胞/cm²。后续传代培养时使用2×10⁴个细胞/cm²。
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。
