01General information

Description

MM1.R细胞系是MM1细胞系的衍生物,MM1细胞系最初是从一名多发性骨髓瘤(MM)患者体内建立的。 MM1.R 是专门为研究地塞米松耐药性而开发的,地塞米松是一种用于治疗 MM 的皮质类固醇。该细胞系为探索糖皮质激素耐药机制以及测试克服 MM 治疗中这一挑战的潜在治疗策略提供了可靠的模型。 与 MM1.S 一样,MM1.R 细胞的特点是高表达白细胞介素-6 (IL-6) 依赖性信号通路,这些通路在 MM 的生物学中起着关键作用。然而,MM1.R 在耐药性方面存在显著差异,这使其成为研究疾病进展和耐药机制的关键工具。

与MM1.S相比,MM1.R细胞表现出转录和信号传导方面的改变,包括糖皮质激素受体活性和NF-κB通路调节方面的差异。 该耐药表型已被证实与凋亡通路的异常有关,在接受地塞米松治疗时,促凋亡信号传导明显减弱。重要的是,关于MM1.R的研究突显了这些通路在治疗耐药性中的作用,为针对多发性骨髓瘤微环境和细胞信号依赖性的新型治疗方法铺平了道路。

MM1.R的用途不仅限于研究地塞米松耐药性。它还是评估联合疗法(包括蛋白酶体抑制剂和免疫调节药物)的宝贵模型。该细胞系经过充分记录的遗传和分子特征(包括其对各种药理学制剂的反应),使其成为多发性骨髓瘤临床前研究中不可或缺的工具。 对MM1.R的进一步转录组学研究表明,尽管它与源自患者的肿瘤特征仍存在一定相似性,但其耐药机制凸显了与非耐药MM模型之间的关键差异,这进一步强调了它在治疗药物研发中的重要性。

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.

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。
