01General information

Description

MOVAS细胞系是一种源自C57BL/6小鼠主动脉平滑肌细胞的小鼠血管平滑肌细胞(VSMC)系。该永生化细胞系保留了平滑肌的关键特征,因此成为研究血管平滑肌细胞生物学和病理生理学的宝贵工具。 MOVAS细胞已被广泛应用于动脉粥样硬化、钙化及细胞信号转导等血管过程的研究。它们表达典型的平滑肌标志物,包括α-平滑肌肌动蛋白(α-SMA),并可在各种实验条件下进行培养,以模拟血管疾病。

MOVAS细胞的主要应用之一是血管钙化研究。当在含有β-甘油磷酸盐和抗坏血酸的钙化培养基中培养时,该细胞系可在体外发生钙化,模拟了原代血管平滑肌细胞中观察到的过程。 MOVAS细胞表现出较高的碱性磷酸酶活性和钙沉积,这些是血管钙化的关键标志。 该模型还通过与原代小鼠主动脉血管平滑肌细胞(VSMCs)的对比验证,显示出对钙化条件以及左旋咪唑和依替膦酸等已知抑制剂治疗的反应与原代细胞相当。这些特征使 MOVAS 成为原代血管平滑肌细胞的一种可靠且经济高效的替代品,既降低了实验变异性,又减少了伦理顾虑。

此外,MOVAS细胞已被用于探索胆固醇代谢——这一对动脉粥样硬化发展至关重要的过程。它们表达ABCA1和ABCG1等必需的胆固醇转运蛋白,并展现出将胆固醇转运至HDL和apoAI的功能。 胆固醇负荷实验证实,这些细胞能够转分化为巨噬细胞样细胞,这一过程与动脉粥样硬化斑块的形成密切相关。这些发现凸显了MOVAS细胞在研究胆固醇稳态、表型可塑性以及血管疾病进展方面的实用价值。

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。
