01General information

Description

MOLM-13细胞系是一种人类急性髓系白血病(AML)细胞系,最初源自一名被诊断为AML-M5a(急性单核细胞白血病,FAB分类)的患者。该细胞系建立于疾病复发时,此前患者曾经历骨髓增生异常综合征(MDS)进展。 MOLM-13细胞携带由插入突变ins(11;9)(q23;p22p23)导致的MLL-AF9基因融合,并呈现8号染色体三体等额外染色体异常,此为AML的常见特征。

表型特征方面,MOLM-13细胞表达髓系和单核细胞相关标志物(包括CD33、CD13和CD15),但缺乏造血干细胞及前体细胞标志物CD34的表达,此特征可将其与其他白血病亚型区分。该细胞系呈现单核细胞样形态,具有细致的染色质和显著的核仁。 功能上,该细胞系在特定细胞因子(如干扰素-γ[IFN-γ]和肿瘤坏死因子-α[TNF-α])刺激下可分化为巨噬细胞样细胞,同时增强髓系单核细胞标志物的表达。

MOLM-13是研究白血病发生机制的关键模型,尤其适用于解析MLL重排白血病的发病机制。该模型在临床前研究中应用广泛,包括评估新型疗法(如CD70特异性CAR-T细胞)——该疗法在体外及异种移植模型中均展现出对MOLM-13的显著疗效。 这使得MOLM-13成为探索高危急性髓系白血病靶向治疗方案的宝贵工具。

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。
