01General information

Description

从人类胶质母细胞瘤中提取的 U87MG 细胞系是神经生物学和癌症研究中使用最广泛的细胞模型之一。这些细胞源自中枢神经系统的恶性肿瘤,表现出多形胶质母细胞瘤(GBM)的许多标志性特征,包括快速增殖、高侵袭性以及显著的遗传和表型异质性。这使得 U87MG 细胞系(又称 U87 细胞)成为探索脑肿瘤分子和细胞机制以及测试潜在治疗策略的宝贵工具。

在神经科学和免疫肿瘤学研究中,U87MG 细胞是阐明胶质母细胞瘤细胞功能和细胞毒性机制的模型,包括探索 NK 细胞的细胞毒性。U87 细胞上 NKG2D 配体的表达和 NKG2D 抗体在研究中的使用,凸显了肿瘤微环境中癌细胞与免疫系统(尤其是 NK 细胞)之间错综复杂的动态关系。

U87胶质母细胞瘤细胞的干性特征及其基因和表型属性是研究的重点,目的是揭示赋予这些细胞高度可塑性和对传统疗法的抵抗力的机制。U87 细胞系的确切来源仍是一个谜,基因分析显示其与原始肿瘤存在差异。

总之,U87 细胞系仍然是胶质母细胞瘤研究的基本工具,有助于加深对该疾病生物学特性的了解,并寻求更有效的治疗方法。

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
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。
