01General information

Description

MM.1S细胞系是MM.1系列的一部分,MM.1系列是从一名多发性骨髓瘤(MM)患者身上开发出来的,用于研究疾病进展的不同阶段和对糖皮质激素(GC)疗法的反应。MM.1S对地塞米松等糖皮质激素特别敏感,可作为研究糖皮质激素诱导多发性骨髓瘤细胞凋亡机制的模型。这种敏感性使 MM.1S 成为研究 MM 治疗早期阶段和导致 GC 反应性的细胞通路的重要工具。

MM.1S 细胞与其他 MM.1 株系一样,表现出典型的骨髓瘤形态,包括核位置偏心的圆形细胞,其中许多是双核或多核细胞。这些细胞表达 CD38 和 PCA-1 等浆细胞特征标记,但缺乏 CD19 和 CD20 等典型的 B 细胞标记,这反映了它们作为浆细胞的终末分化状态。它们还表现出高水平的免疫球蛋白λ(λ)轻链表达,这与其来源一致。这种细胞系对于探索 MM 的药物作用、耐药性和凋亡途径至关重要,尤其是在 GC 治疗的背景下。

MM.1S 的主要特征之一是依赖功能性糖皮质激素受体(GR)对药物产生反应。在 MM.1S 中,高水平的野生型 GR 能使地塞米松有效诱导细胞凋亡,为研究这一过程的分子事件提供了一个宝贵的系统。该品系经常与其耐药的对应品系 MM.1R 进行比较,以研究 GC 耐药的机制,这是治疗 MM 的一个关键问题。总之,MM.1S 细胞系为多发性骨髓瘤的药物敏感性、疾病进展和潜在治疗策略提供了见解。

06Handling and culture

Culture medium
RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% 热灭活 FBS
Dissociation reagent
Accutase
Subculturing
将悬浮细胞收集到 15 毫升试管中,用不含钙和镁的 PBS(T25 烧瓶用 3-5 毫升,T75 烧瓶用 5-10 毫升)轻轻清洗粘附的细胞。涂抹 Accutase(T25 烧瓶 1-2 毫升,T75 烧瓶 2.5 毫升),确保完全覆盖细胞层。让细胞在室温下孵育 10 分钟。孵育后,将悬浮细胞和粘附细胞混合并离心。离心后,小心重悬细胞团,并将细胞悬浮液转移到装有新鲜培养基的新烧瓶中。
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。
