01General information

Description

HS-5细胞系是一种源自人类骨髓的间充质干细胞(MSC)模型,常用于研究间充质干细胞在造血和癌症发生中的支持作用。 HS-5细胞最初通过人乳头瘤病毒E6和E7基因分离并永生化,具有成纤维细胞样形态,且以分泌多种对造血细胞和免疫细胞相互作用至关重要的细胞因子和生长因子而著称。 值得注意的分泌因子包括粒细胞集落刺激因子(G-CSF)、粒细胞-巨噬细胞集落刺激因子(GM-CSF)、 巨噬细胞集落刺激因子(M-CSF)、干细胞因子(SCF)、白细胞介素-6(IL-6)、IL-8和IL-11等。 这些分泌物使HS-5细胞能够在体外维持造血祖细胞的生长和增殖,即使在无血清条件下也是如此,这凸显了它们在支持造血方面与原代间充质干细胞(MSCs)的功能相似性。

在肿瘤学研究中,HS-5细胞可作为研究MSCs与癌细胞之间相互作用的模型,特别是在研究肿瘤微环境介导的癌细胞存活、免疫调节和耐药性方面。 研究表明,HS-5细胞能够保护急性髓系白血病(AML)细胞免受阿糖胞苷(Ara-C)和柔红霉素(DNR)等化疗药物诱导的凋亡,其作用机制可能涉及细胞因子信号传导和直接的细胞间相互作用。 HS-5细胞的这种保护作用会增强AML细胞的增殖并降低化疗疗效,因此该细胞系成为模拟骨髓微环境中药物耐药性的宝贵工具。此外,HS-5细胞表达CD73、CD90和CD105等MSC标志物,尽管其表达水平可能与原代MSC存在差异。

此外,HS-5细胞已被用于探索新型治疗方法,例如测试原始石墨烯等纳米材料的细胞毒性作用。 研究表明,HS-5细胞暴露于石墨烯会诱发线粒体功能障碍和氧化应激,通过增加活性氧(ROS)的产生和破坏线粒体膜电位从而引发凋亡,因此该细胞系可作为评估纳米颗粒在肿瘤微环境中与间质细胞相互作用时的毒性和治疗潜力的模型。

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。
