01General information

Description

UM-HMC-1 是一种人黏液表皮样癌细胞系,源自一名 76 岁非裔美国男性患者的前颊腺原发性唾液腺肿瘤。 该细胞系是密歇根大学人类黏液表皮样癌(UM-HMC)细胞系组合中的一个。 UM-HMC-1 携带 CRTC1-MAML2 基因融合(也称为 MECT1-MAML2),这是大多数黏液表皮样癌中具有决定性意义的致癌事件,由 t(11;19)(q21;p13) 染色体易位所致。该融合基因可激活 CREB 靶基因和 Notch 通路组分,从而驱动肿瘤的增殖和存活。

UM-HMC-1 适用于唾液腺黏液表皮样癌生物学、CRTC1-MAML2 融合致癌基因信号传导、CREB 通路激活、Notch 通路失调以及融合基因驱动型癌症的靶向治疗等研究。 该细胞系可用于药物敏感性检测、侵袭与迁移研究,并作为 UM-HMC 多系细胞面板的一部分,用于唾液腺肿瘤生物学的比较表征。

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。
