01General information

Description

HROG06 T0 M2系由一名成人患者新鲜切除的肿瘤组织建立的人源性原发性多形性胶质母细胞瘤(GBM)细胞系,该患者被诊断为WHO IV级胶质母细胞瘤。 标记"T0"表示该肿瘤样本取自初次手术,而"M2"则指从同一原发肿瘤独立建立的第二代体外模型。该细胞系在HROG(汉萨城市罗斯托克胶质瘤)平台中开发,该平台专注于建立超低代次胶质瘤培养体系,以保留原发肿瘤的生物学及分子特征。

HROG06 T0 M2在标准化培养条件下呈粘附生长,展现原发性胶质母细胞瘤培养物典型的纺锤形成纤维细胞样形态。HROG系列免疫表型分析显示其表达神经胶质细胞谱系标志物(如胶质纤维酸性蛋白GFAP、神经胶质细胞粘着蛋白nestin及波形蛋白vimentin),证实其星形胶质细胞肿瘤起源。 HROG平台的分子特征鉴定涵盖临床相关生物标志物评估,包括MGMT启动子甲基化状态、EGFR扩增,以及TP53、IDH1/2、KRAS和BRAF等基因的突变谱分析,证实早期传代培养中肿瘤相关基因组改变得以完整保留。

HROG06 T0 M2细胞系已被用于体外评估标准胶质母细胞瘤治疗方案(包括烷化剂类化疗药物及靶向抑制剂)的疗效。 HROG细胞库的比较分析表明,早期传代细胞具有稳定形态、可重复的生长动力学及一致的药物敏感性谱,证实其作为转化研究模型的适用性。作为患者来源的低传代胶质母细胞瘤细胞系,HROG06 T0 M2为研究胶质母细胞瘤生物学特性、肿瘤异质性及治疗耐药机制提供了临床相关性研究平台。

04Handling and culture

Culture medium
DMEM:Ham's F12(1:1),w: 3.1 g/L 葡萄糖,w: 2.5 mM L-谷氨酰胺,w: 15 mM HEPES,w: 0.5 mM 丙酮酸钠,w: 1.2 g/L NaHCO3(Cytion 文章编号 820400a)。
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.

05Quality 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。
