01General information

Description

SW-1736是一种人类甲状腺未分化癌细胞系,常用于研究侵袭性强且分化程度低的甲状腺癌。该细胞系最初源自一名未分化甲状腺癌患者,这种癌症虽罕见但极具侵袭性,以进展迅速、预后不良为特征。 由于能高度复现甲状腺未分化癌(ATC)的恶性特征——包括对化疗、放疗等标准治疗的耐药性——SW-1736细胞系在癌症研究中被广泛应用。

该细胞系的显著特征在于其常被用于研究细胞分裂异常与肿瘤转移机制。研究人员观察到非典型分裂事件(如1:4分裂),这正是未分化甲状腺癌中具有侵袭性且失控的生长模式的标志性表现。 此外,SW-1736细胞经转染多种报告基因(如-Luc)后,可实现非侵入性体内成像研究。这类研究常在小鼠模型中开展,旨在探究甲状腺癌的转移潜能,特别是向肺部和骨骼等器官的扩散机制。

此外,SW-1736细胞系还被用于探索潜在治疗策略,包括二甲双胍与依托泊苷、表柔比星等标准化疗药物的联合应用。研究表明二甲双胍能增强这些药物的细胞毒性效应,显著提升SW-1736细胞的凋亡与坏死诱导率。该联合疗法在抑制癌细胞迁移和增殖方面展现出良好前景,有望为治疗侵袭性甲状腺癌开辟新的治疗途径。

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。
