01General information

Description

HEC-1-A 细胞是一种特征明确的人类子宫内膜腺癌细胞系,来源于一名 71 岁高加索妇女的恶性组织。该细胞系建立于 20 世纪 70 年代中期,被广泛用于妇科癌症研究,尤其是研究子宫内膜癌。

从形态上看,HEC-1-A 细胞类似上皮细胞,培养时形成单层多角形细胞。它们表现出稳健和粘附的生长模式,这是源自实体瘤的上皮细胞的典型特征。HEC-1-A 细胞的形态特征使其成为研究粘附、迁移和侵袭等癌症进展核心细胞行为的重要模型。

从基因型上看,HEC-1-A 细胞存在几种与癌症生物学相关的基因畸变,包括 p53 和 PTEN 等关键调控基因的突变,而这两种基因在子宫内膜癌中都很常见。这些遗传特征有助于研究子宫内膜癌发生的分子基础以及导致肿瘤生长和抗药性的细胞通路。

使用 HEC-1-A 细胞进行的研究极大地促进了我们对子宫内膜癌的了解,尤其是在激素影响、基因突变和对化疗药物的反应方面。因此,该细胞系在开发更有效的子宫内膜癌诊断和治疗策略方面继续发挥着重要作用。

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。
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。
