01General information

Description

SW-579 是一种人类甲状腺鳞状细胞癌细胞系,在癌症研究中常用来研究甲状腺癌的进展和侵袭性。该细胞系在探索基质金属蛋白酶(MMPs)和整合素在癌细胞侵袭中的作用的研究中尤其有价值。涉及SW-579的研究表明,骨硅蛋白(BSP)通过与MMP-2和整合素αvβ3形成三分子复合物,显著增强了这些细胞的侵袭性。 这种复合物促进了癌细胞在细胞外基质中的移动,模拟了转移性癌症的侵袭行为。

使用改良波登室侵袭试验进行的体外实验表明,与未处理的对照组相比,用 BSP 处理 SW-579 细胞可使其侵袭性增加约 10 倍。研究发现,这种侵袭性的增强是由 MMP-2 和整合素 αvβ3 介导的,因为阻断整合素或 MMP-2 会显著降低这种效应。这些发现强调了MMPs和整合素在甲状腺癌转移潜能中的关键作用,使SW-579成为研究旨在破坏这些途径的靶向疗法的有用模型。

此外,BSP参与了SW-579细胞的侵袭性,这为抑制甲状腺癌的转移提供了潜在的治疗靶点。通过干扰BSP-MMP-2-整合素αvβ3复合物的形成,研究人员或许能降低这些癌细胞的侵袭性,为限制甲状腺癌在患者体内的扩散提供一种有前景的方法。

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.

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。
