01General information

Description

U-CH1细胞系是首个建立的人类脊索瘤永久细胞模型,源自复发性骶骨脊索瘤。脊索瘤是一种罕见的、生长缓慢的局部侵袭性肿瘤,起源于脊索残余组织,主要发生于轴向骨骼沿线。 U-CH1细胞呈现软骨瘤特有的细胞遗传学特征,包括克隆性染色体畸变(如der(1)t(1;22))、4号、5号、6号、9号、10号及20号染色体缺失,以及由t(10;20)导致的20号染色体衍生染色体。 比较基因组杂交技术揭示软骨瘤存在反复出现的DNA拷贝数改变,尤其表现为1p和3p区域缺失及7q、5q、12q和20区域增益。U-CH1细胞的细胞遗传学特征与其原发肿瘤高度一致,进一步证实了其生物学相关性。

功能与分子层面,U-CH1及其他软骨瘤细胞系均呈现该肿瘤的标志性特征,包括表达被视为关键诊断标志物的转录因子brachyury。U-CH1还存在CDKN2A缺失及p16蛋白表达缺失,此为软骨瘤中反复出现的遗传改变。 该改变导致CDK4/6通路过度激活,使U-CH1对帕博西尼等CDK4/6抑制剂敏感。帕博西尼治疗显著降低体外磷酸化Rb水平并抑制细胞增殖,表明U-CH1可作为评估细胞周期靶向疗法的宝贵临床前模型。 该细胞系还通过mRNA和蛋白质谱分析得到验证,证实其在表达和基因组模式上具有代表性,能反映原发性软骨肉瘤肿瘤的特征。

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。
