01General information

Description

HBL-52 是一种人体细胞系,来源于过渡性脑膜瘤 I 级,具体位于视管。该细胞系来源于一名成年女性患者,具有上皮样形态。脑膜瘤是典型的良性肿瘤,起源于脑膜,即大脑和脊髓周围的膜层。过渡亚型代表了一种组织学类型,肿瘤细胞显示出纤维和脑膜上皮特征的混合。

最近的研究强调了 HBL-52 细胞对白藜芦醇的反应性,白藜芦醇是一种天然多酚,具有显著的抗炎和抗癌特性。研究发现,白藜芦醇能抑制 HBL-52 脑膜瘤细胞的增殖,这表明它在管理或治疗脑膜瘤方面具有潜在的治疗作用,尤其是那些位于视管等重要部位的脑膜瘤。这种对细胞增殖的抑制作用凸显了 HBL-52 在药理学研究和药物测试中的实用性,为评估可能影响肿瘤生长动态的化合物的疗效提供了一个宝贵的模型。鉴于其起源和良性性质,HBL-52 细胞系是研究脑膜瘤发病机制的宝贵模型,特别是在了解脑膜瘤在视管等独特解剖部位的发展和进展的细胞行为和分子机制方面。

06Handling and culture

Culture medium
McCoys 5a,w:3.0 克/升葡萄糖,w:稳定谷氨酰胺,w:2.0 毫摩尔丙酮酸钠,w:2.2 克/升 NaHCO3(Cytion 文章编号 820200a)。
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。
Seeding density
5×10³个细胞/平方厘米的密度约4天可形成融合细胞层。不建议使用超过9×10³个细胞/平方厘米的接种密度。
Fluid renewal
每周 2 至 3 次
Post-thaw recovery
让细胞粘附至少 24 到 48 小时。
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
作为冷冻保存培养基,我们使用 50% 基础培养基 + 40% FBS + 10% DMSO 或 CM-1(Cytion 目录号 800100),其中包括优化的渗透保护剂和代谢稳定剂,以促进恢复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。
