01General information

Description

Bend.3 细胞系来源于小鼠脑内皮细胞,被广泛用于神经血管研究。这些细胞是研究血脑屏障(BBB)的模型,血脑屏障是调节物质从血液进入大脑的关键结构。Bend.3 细胞有助于探索支配血脑屏障完整性、渗透性和运输功能的分子和细胞机制。研究人员利用 Bend.3 细胞研究各种神经系统疾病的病理生理学,如中风、阿尔茨海默病和多发性硬化症,这些疾病的特征就是 BBB 功能障碍。

Bend.3 细胞具有内皮细胞的特征,包括表达紧密连接蛋白,如闭塞素、克劳丁蛋白和闭塞带-1(ZO-1),这些蛋白对维持 BBB 的选择性通透性至关重要。它们还表达 CD31 和 von Willebrand 因子等典型的内皮细胞标记。Bend.3 细胞对炎症刺激和氧化应激有反应,因此适合用于研究 BBB 破坏和神经炎症。此外,Bend.3 细胞系还可用于评估药剂穿越 BBB 的有效性和安全性,从而帮助开发治疗中枢神经系统疾病的药物。Bend.3细胞在神经血管单元建模中的实用性凸显了它们在促进我们对脑内皮细胞生物学的了解和神经治疗药物开发方面的重要性。

GMO status details
GMO-S1: This murine endothelial cell line (bEnd.3) contains a polyomavirus middle T antigen encoded by the NTKmT retroviral vector, driving transformation and enhanced proliferation. The construct is stably present in brain microvascular endothelial cells. This classification applies only within Germany and may differ elsewhere.

06Handling and culture

Culture medium
DMEM,w:4.5 克/升葡萄糖,w:4 毫摩尔 L-谷氨酰胺,w:3.7 克/升 NaHCO3,w:1.0 毫摩尔丙酮酸钠(Cytion 编号 820300a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

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。
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。
