01General information

Description

MUM2B细胞系是一种源自葡萄膜黑色素瘤肝转移灶的转移性葡萄膜黑色素瘤模型。该细胞系在眼科肿瘤学研究中被广泛应用,用于研究转移性葡萄膜黑色素瘤的侵袭性和扩散特性。 与原发性葡萄膜黑色素瘤细胞系不同,MUM2B 表现出更强的转移活性,因此成为理解晚期黑色素瘤进展及治疗耐药性的关键工具。

研究表明,MUM2B细胞保留了S-100、HMB-45和Melan-A等关键黑色素瘤标志物,证实了其源自黑色素细胞。此外,该细胞系的特征在于其能在体外模拟血管生成模式,这一现象与肿瘤的侵袭性和转移潜力密切相关。 MUM2B已被用于研究驱动黑色素瘤进展的分子机制,包括凋亡抵抗通路和线粒体功能障碍的作用。该细胞系以p53非依赖性方式对NOXA等特定凋亡诱导剂作出反应,这凸显了其在探索针对凋亡抵抗性肿瘤的治疗策略方面的实用价值。

利用MUM2B开展的研究为识别转移性黑色素瘤的潜在治疗靶点做出了重大贡献。 研究表明,该细胞系对γ-分泌酶抑制剂(GSI)等创新化合物敏感,这些化合物可在选择性诱导黑色素瘤细胞凋亡的同时,不损伤正常黑色素细胞。这些发现凸显了MUM2B作为测试新型治疗药物及加深对转移性葡萄膜黑色素瘤生物学认识的重要模型的作用。

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
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。
