01General information

Description

SK-UT-1细胞系源自人类子宫平滑肌肉瘤(ULMS),这是一种起源于子宫平滑肌的高侵袭性癌症。该细胞系是研究ULMS肿瘤发生、转移及药物耐药性的关键模型。SK-UT-1细胞具有肉瘤特征,包括快速增殖、分化不良及对常规疗法的耐药性。 该细胞系尤其用于研究癌干细胞样细胞(CSCs),这类细胞在癌症复发和化疗耐药性中起着重要作用。研究发现SK-UT-1细胞中存在CD133+癌干细胞亚群,其具有增强的自我更新能力、集落形成能力和抗凋亡特性。

基于SK-UT-1细胞的研究重点在于表征CD133+ CSCs,揭示其形成肿瘤球的能力——这是干细胞样行为的标志性特征。该亚群在体内具有增强的致瘤潜力,即使少量细胞(10⁴个)也足以在异种移植模型中引发肿瘤形成。 CD133+细胞对多柔比星等化疗药物具有耐受性,进一步印证其在治疗耐药性中的关键作用。此外,与CD133−细胞相比,CD133+细胞中CD44、ALDH1和BMI1等癌干细胞相关标志物表达水平显著升高,证实其癌干细胞身份。

SK-UT-1细胞已成为理解ULMS进展机制及开发潜在治疗策略的关键工具。通过靶向肿瘤内CD133+癌干样细胞群,有望从转移和化疗耐药的根本原因入手,为改善ULMS患者预后提供前景广阔的治疗途径。

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.

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。
