01General information

Description

HCC1428 是一种人类乳腺癌细胞系,根据全基因表达谱被归类为腔隙型 B。它源于原发性乳腺肿瘤,保留了管腔型乳腺癌的主要特征,包括雌激素受体(ER)的表达。在乳腺癌细胞系和原发肿瘤的转录组学比较分析中,HCC1428始终与管腔B亚型肿瘤聚集在一起,后者具有更高的增殖指数和不同于管腔A肿瘤的基因表达特征。

在功能上,与其他乳腺癌亚型相比,HCC1428 细胞表现出中等水平的增殖和分化。它们对雌激素有反应,并保持成熟的管腔表型,表达与乳腺分化上皮系相关的标记。在临床前研究中,HCC1428 等管腔 B 细胞系通常被用来评估内分泌疗法和耐药机制,因为与管腔 A 亚型相比,管腔 B 细胞系部分依赖 ER 信号传导,而且增殖能力更强。

HCC1428也是癌症细胞系百科全书(CCLE)的一部分,该百科全书提供了遗传学、转录组学和药理学特征的综合数据集。这些数据表明,HCC1428带有典型的ER阳性腔隙型乳腺癌的基因表达和拷贝数改变。因此,该细胞系是研究激素受体阳性乳腺癌的宝贵模型,特别是在管腔B特异性生物学和对靶向疗法的反应方面。

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。
