01General information

Description

MUG-Chor1细胞系是一种特征明确的体外模型,源自一名高加索族女性患者的复发性骶尾部脊索瘤。 脊索瘤是一种罕见的恶性肿瘤,起源于轴向骨骼沿线的脊索残余组织。MUG-Chor1 细胞系是通过机械和酶解方式对肿瘤组织进行解聚后建立的,并在优化条件下进行培养以维持其生长。 该细胞系保留了软骨肉瘤的标志性特征,包括表达短尾蛋白(brachyury)——这种转录因子对脊索分化至关重要,也是软骨肉瘤的诊断标志物。此外,MUG-Chor1 还表达细胞角蛋白、EMA、波形蛋白和 S-100 蛋白,进一步证实了其源自软骨肉瘤。

从遗传学角度看,MUG-Chor1 反映了脊索瘤典型的染色体和分子改变,包括 6q27 染色体上 brachyury (T) 基因座的增益,以及 9p24.3-p13.1 区域(涵盖 CDKN2A/CDKN2B 基因座)的缺失。 该细胞系还显示出10q25.2等位点(包含PTEN)以及与肿瘤进展相关的其他区域的缺失。这些遗传特征使MUG-Chor1成为研究脊索瘤生物学及评估治疗干预措施的宝贵工具。

MUG-Chor1的生长速度较慢,倍增时间为7-10天,这反映了脊索瘤的临床行为特征——该肿瘤以生长缓慢但局部侵袭性强而著称。 该细胞系在临床前研究中发挥了关键作用,包括已筛选出潜在治疗药物(如EGFR抑制剂)的药物筛选研究。这些抑制剂在脊索瘤模型中已显示出降低细胞存活率和抑制肿瘤生长的疗效,这突显了MUG-Chor1在转化研究中的重要性。

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.

06Quality 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。
