01General information

Description

A2780 是一种人类卵巢癌细胞系,最早于 1972 年从一名晚期上皮性卵巢癌患者身上建立。这种细胞的特点是对顺铂和多柔比星这两种常用的卵巢癌化疗药物敏感。自建立以来,A2780 已被广泛用于癌症研究,特别是癌症新疗法的开发和测试。

使用 A2780 细胞进行的研究为了解卵巢癌的生物学特性提供了宝贵的资料,包括确定特定的基因突变,如 TP53 和 BRCA1。这些突变与卵巢癌风险增加有关,在其他类型的癌症中也有发现。

此外,A2780 细胞还被用于研究血管生成(新血管形成的过程)在卵巢癌进展中的作用,以及评估抗血管生成药物的疗效。血管生成在卵巢癌的生长和进展过程中起着至关重要的作用,因为它为癌细胞的生长提供氧气和营养。

使用 A2780 细胞进行的研究表明,血管内皮生长因子(VEGF)和血管生成素-2 等促血管生成因子过度表达,这些因子可促进新血管的形成。此外,A2780 细胞还被用于测试贝伐单抗等抗血管生成药物的疗效,这些药物以血管内皮生长因子为靶点,抑制新血管的形成。

此外,A2780 细胞还被用于评估各种治疗药物的疗效,包括化疗药物、PARP 抑制剂等靶向疗法和免疫疗法。

特别是,A2780 细胞被用于研究不同药物组合对癌细胞增殖、凋亡和耐药性的影响。总之,A2780 细胞系在推动卵巢癌研究方面发挥了重要作用,为了解该疾病和开发新的治疗方法提供了宝贵的工具。

Dissociation reagent
Accutase
Subculturing
将悬浮细胞收集到 15 毫升试管中,用不含钙和镁的 PBS(T25 烧瓶用 3-5 毫升,T75 烧瓶用 5-10 毫升)轻轻清洗粘附的细胞。涂抹 Accutase(T25 烧瓶 1-2 毫升,T75 烧瓶 2.5 毫升),确保完全覆盖细胞层。让细胞在室温下孵育 10 分钟。孵育后,将悬浮细胞和粘附细胞混合并离心。离心后,小心重悬细胞团,并将细胞悬浮液转移到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。
