01General information

Description

NOMO-1细胞系源自一名被诊断为急性单核细胞白血病(AML-M5a)的31岁女性患者。该细胞系表现出前单核细胞特征,因此是研究单核细胞白血病及分化的可靠模型。 NOMO-1细胞对分化诱导剂(如佛波酯类,例如12-o-十四碳酰基佛波酯-13-乙酸酯或TPA)表现出反应性,从而使其成熟为巨噬细胞样细胞。 分化后,这些细胞表现出纤维连接蛋白等标志物的表达增加,并分泌白细胞介素 IL-1α 和 IL-1β,这些物质对免疫应答和炎症通路至关重要。

这些细胞在研究凝血和纤溶系统方面也起着关键作用。NOMO-1细胞分泌组织因子(TF)、纤溶酶原激活剂(PA)和纤溶酶原激活剂抑制剂(PAI),其分泌水平受分化诱导剂的调节。 TPA 处理可增强 TF 和 PA(尤其是尿激酶型纤溶酶原激活剂 [uPA])的产生,同时增加 PAI 的分泌,这表明 NOMO-1 细胞对于理解白血病中的止血和血栓形成机制具有重要意义。

从遗传学角度看,NOMO-1细胞携带t(9;11)(p22;q23)易位,从而产生MLL-AF9融合基因,这是某些AML亚型的标志性特征。 这种易位通过扰乱与造血分化和增殖相关的基因表达程序,从而驱动白血病发生。这种易位的存在使 NOMO-1 成为探索 MLL 重排白血病和评估靶向治疗的重要工具。

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。
