01General information

Description

SNB-19 细胞系是一种人类多形性胶质母细胞瘤(GBM)模型,来源于高级别胶质瘤肿瘤。它是被广泛研究的胶质瘤细胞系之一,用于探索侵袭性脑肿瘤,尤其是胶质母细胞瘤的生物学特性。SNB-19 细胞呈现上皮形态,在培养过程中具有粘附性。它们被广泛用于研究肿瘤的增殖、侵袭和对治疗的反应,特别是用于研究胶质母细胞瘤对常规治疗的抗性机制。

对SNB-19细胞进行的基因组剖析发现了常见于胶质母细胞瘤的重要基因改变,包括肿瘤抑制基因和TP53、表皮生长因子受体(EGFR)和PTEN等致癌基因的突变。这些细胞还显示出染色体异常,包括致癌驱动基因的扩增和抑癌基因位点的缺失。SNB-19 的遗传结构为研究驱动 GBM 发病机制的分子通路和确定潜在的治疗靶点提供了一个重要的模型。

SNB-19 已被广泛用于评估新型化疗药物和靶向药物的疗效。该细胞系还被用于研究胶质母细胞瘤的侵袭性和迁移性,因为它能有效模拟 GBM 在体外的高侵袭性。此外,SNB-19 的蛋白质组分析有助于了解胶质母细胞瘤中蛋白质水平的失调及其与基因改变的相关性。这些特点使 SNB-19 成为胶质母细胞瘤转化研究的重要工具。

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。
