01General information

Description

HCC1954 细胞系来源于人类成年乳腺癌患者的原发性导管癌。该细胞系被广泛用于乳腺癌研究,特别是用于研究 HER2 阳性(HER2+)和三阴性乳腺癌的遗传和分子特征。HCC1954 细胞表达 HER2,并具有 PIK3CA 基因突变,因此是研究癌症进展和靶向疗法开发过程中信号通路的重要模型。

HCC1954 细胞呈现上皮形态,在体外和体内均具有侵袭性生长特性。它们表达与侵袭性乳腺癌表型相关的标记,包括 HER2/neu,但不表达雌激素受体(ER)和孕酮受体(PR),因此被归类为三阴性乳腺癌细胞。这种细胞系被广泛用于评估曲妥珠单抗等 HER2 靶向疗法以及新型 PI3K 抑制剂的疗效和作用机制。此外,HCC1954 细胞还被用于确定耐药性生物标志物和探索联合治疗策略以提高治疗效果的研究中。HCC1954 细胞系在了解侵袭性乳腺癌的生物学特性和开发有效治疗方法方面的相关性,凸显了 HCC1954 细胞系在肿瘤研究中的重要意义。

06Handling 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
用 10% FBS 补充培养基,加入 2.5 克/升葡萄糖、10 毫摩尔 HEPES 和 1 毫摩尔丙酮酸钠
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。
Fluid renewal
每周 2 至 3 次
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。
