01General information

Description

SKM-1细胞系是一种人类白血病模型,由一名急性单核细胞白血病患者的外周血建立而成,该患者的疾病源于骨髓增生异常综合征(MDS)。 这些细胞呈现未成熟形态特征,如核质比高、细小的嗜天青颗粒,使其成为研究白血病分子和细胞机制的理想模型,特别是研究MDS向急性髓系白血病(AML)转化的过程。

SKM-1细胞的基因分析揭示了重要染色体异常,包括del(9)(q13;q22)和der(17)t(17:?)(p13:?);后者涉及p53基因,该基因在此细胞系中过度表达并携带突变。这些发现凸显了p53在髓系恶性肿瘤克隆演变与进展中的关键作用。 SKM-1细胞还具有表达髓单核细胞标志物(包括CD4、CD13和CD33)的特征,并呈现丁酸酯酶活性阳性,这与其单核细胞谱系相吻合。

该细胞系广泛应用于白血病发生机制、药物耐药性及白血病分子通路研究。例如,SKM-1为探究p53功能障碍及其他遗传缺陷对细胞增殖和治疗反应的影响提供了研究平台,同时也是探索骨髓增生异常综合征和继发性急性髓系白血病新型治疗策略的理想模型。

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。
