01General information

Description

CAL-51细胞系是一种人乳腺腺癌模型,由晚期乳腺癌患者的恶性胸腔积液建立而成。该细胞系具有上皮形态特征和正常的二倍体核型,其显著特点在于呈现三阴性乳腺癌(TNBC)特征——缺乏雌激素受体(ER)、孕激素受体(PR)及HER2表达。 这些常被用作治疗靶点的标志物缺失,使CAL-51成为研究TNBC的宝贵模型——该侵袭性乳腺癌亚型治疗手段有限。CAL-51在免疫缺陷小鼠中的致瘤性及软琼脂培养基中的生长能力,彰显其恶性潜能,使其适用于体外与体内癌症研究。

CAL-51在研究SARS-CoV-2感染机制方面同样具有实用价值。该细胞高表达病毒入侵因子ACE2、TMPRSS2及神经肽素-1(NRP1),使其成为SARS-CoV-2的易感宿主,能有效促进病毒在细胞培养中的侵入与复制。 这使CAL-51成为探索病毒致病机制、测试抗病毒化合物及针对SARS-CoV-2的中和抗体的理想模型。实验证实治疗性抗体能在CAL-51细胞中有效阻断SARS-CoV-2入侵,凸显其作为COVID-19研究模型系统及潜在治疗评估平台的价值。

在癌症研究中,CAL-51细胞系尤其适用于探究肿瘤异质性,特别是通过其亚群(side populations, SP)——这类干细胞样癌细胞亚群高表达ABCG2转运蛋白。 CAL-51中的SP细胞具有增强的药物耐受性和潜在自我更新能力,这些特性对研究癌症干细胞行为及治疗耐药性具有重要意义。因此,CAL-51作为多功能模型,既能推动癌症研究又能助力病毒感染研究,为三阴性乳腺癌(TNBC)和SARS-CoV-2等治疗难点领域的研究提供支持。

05Handling 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。

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。
