01General information

Description

HMEC-1 细胞,或称人类微血管内皮细胞-1,是一种从人类真皮微血管内皮细胞中提取的永生细胞系。开发这种细胞系是为了促进对微血管内皮功能和病理的研究。HMEC-1 细胞能保留原代内皮细胞的许多表型和功能特征,因此被广泛用于血管生物学研究。

HMEC-1 细胞显示典型的内皮细胞标记,如 CD31(PECAM-1)、von Willebrand 因子和 VE-cadherin。这使它们在研究血管生成(即由原有血管形成新血管)方面特别有价值,而血管生成是伤口愈合、癌症生长和心血管疾病等生理和病理情况下的一个关键过程。

这些细胞还可用于探索内皮细胞对炎症细胞因子的反应、内皮层的屏障功能以及内皮细胞与免疫细胞等其他细胞类型之间的相互作用。HMEC-1 细胞可进行基因操作,使研究人员能够研究特定基因对内皮功能的影响,并建立各种血管疾病的模型。

此外,HMEC-1 细胞还是研究内皮屏障通透性的模型系统,这对药物输送和病原体穿过内皮屏障的传染病发病机制至关重要。该细胞系的多功能性和易用性使其继续成为微血管内皮细胞生物学和病理学研究的基石。

06Handling and culture

Culture medium
阿尔法 MEM,含:2.0 mM 稳定谷氨酰胺,不含:2.0 mM 稳定谷氨酰胺,不含:2.0 mM 稳定谷氨酰胺:不含核糖核苷,不含脱氧核糖核苷:脱氧核苷,含 1.0 毫摩尔丙酮酸钠,含 2.2 克/升 NaHCO3
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS、10 纳克/毫升表皮生长因子、1 微克/毫升氢化可的松、10 毫摩尔谷氨酰胺
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。
