01General information

Description

SW1088 细胞系是从大脑皮层肿瘤活检中提取的人类胶质瘤细胞系。它在组织学上被归类为星形细胞瘤,最初是在一项关于能在裸鼠体内形成肿瘤的致瘤人类细胞系的研究中被报道的。在这种情况下,SW1088 被证明可在免疫缺陷宿主皮下接种后形成实体瘤,尽管与更具侵袭性的胶质母细胞瘤细胞系相比,肿瘤的发展需要更长的潜伏期。这表明SW1088细胞在体内的增殖性或侵袭性较低。

SW1088 细胞表现出与星形胶质细胞起源一致的特征,通常用于神经肿瘤学研究,以建立低级别胶质瘤模型。与 U87MG 或 U251 等高级别胶质母细胞瘤模型相比,SW1088 细胞的体内致瘤性较慢,这反映了与星形细胞瘤病理学相关的生物学特征。对 SW1088 进行基因组和转录组分析有助于了解胶质瘤亚型之间的分子差异。然而,由于这些细胞的增殖能力较低,快速形成肿瘤的能力较弱,因此它们可能无法完全再现高级别胶质瘤的表型,因此更适合作为研究早期或侵袭性较低的胶质瘤的模型。

Karyotype
高倍体;模式数 = 72 到 74。高倍体率为 4.2%。大多数染色体形态正常。所有细胞共有三条标记染色体:del(1) (q11)、der(9)t(7;?;9) (q11?;?;p24)和der(10)t(4;10) (q21;q15)。少数细胞中通常有一个,但偶尔也会出现三个双分(DM)。在大多数细胞中,正常的 N5、N7 和 N20 有五个拷贝。在 QM 染色制备中证实了 Y 染色体的存在。

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Fluid renewal
每周 2 至 3 次
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。
