01General information

Description

Kasumi-1 细胞系来自一名 7 岁日本男孩的外周血,他患有急性髓性白血病(AML),特别是 FAB M2 亚型,在骨髓移植后复发。该细胞系是研究血液系统恶性肿瘤,尤其是涉及 t(8;21) 染色体易位的恶性肿瘤的研究人员的宝贵资源。这种易位会导致 AML1-ETO 融合基因的形成,而 AML1-ETO 融合基因是急性髓细胞性白血病某些亚型的关键因素。因此,Kasumi-1细胞是研究急性髓细胞性白血病分子机制和测试潜在治疗方法的重要模型。

Kasumi-1 细胞同时具有髓系和巨噬细胞系的特征,因此特别适用于研究髓系分化。用光滑醇 12-肉豆蔻酸 13-乙酸酯(TPA)培养这些细胞时,可诱导它们分化成巨噬细胞样细胞,从而为探索髓系承诺和分化所涉及的途径提供了一个强大的系统。这种分化能力提高了 Kasumi-1 细胞在研究急性髓细胞性白血病生物学和更广泛的髓细胞发育过程中的实用性。

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。
