01General information

Description

Z-138是一种源自人类套细胞淋巴瘤(MCL)的细胞系,该患者最初表现为慢性淋巴细胞白血病(CLL),随后转化为侵袭性B细胞白血病。 Z-138 细胞表现出成熟 B 细胞表型,表达 CD19、CD20 和表面免疫球蛋白等标志物,同时保持 CD5 阳性,这是套细胞淋巴瘤的特征性表现。这些细胞在对治疗药物的反应方面,特别是针对 BCL-2 抑制剂的反应方面,已受到广泛研究。 研究表明,Z-138细胞对选择性BCL-2抑制剂维奈托克敏感,该药物可通过激活线粒体通路诱导凋亡。 然而,已发现对维奈托克产生耐药性的机制,包括PI3K/AKT通路的上调,这突显了针对BCL-2和PI3K/AKT信号传导同时进行联合治疗的潜力。

Z-138细胞已被用于研究细胞因子介导的细胞毒性,例如白细胞介素-21(IL-21)诱导的凋亡。 虽然某些MCL细胞系对IL-21治疗有反应,但Z-138表现出耐药性,这很可能是由于凋亡信号传导途径的内在差异所致。这种耐药模式揭示了MCL的异质性,并强调了个性化治疗方案的必要性。 Z-138是研究MCL发病机制和测试新型治疗策略的重要临床前模型。

06Handling and culture

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Subculturing
通过定期添加或更换培养基来维持细胞培养。初始培养时细胞密度应为5×10⁵个细胞/毫升,并保持细胞浓度在3×10⁵至1×10⁶个细胞/毫升范围内以获得最佳生长效果。
Fluid renewal
每周 2 至 3 次
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。
