01General information

Description

JVM-3 是一种从一名 73 岁高加索族男性患者的外周血中建立的人 B 细胞前淋巴细胞白血病(B-PLL)细胞系。 该细胞系以淋巴母细胞样细胞的形式在悬浮培养中生长,可呈单个或松散簇状,是B-PLL(一种罕见且侵袭性强的成熟B细胞白血病)的常用模型。 JVM-3 携带 TP53 突变(p.Pro1435Leu 杂合子和 p.Lys601Asn 杂合子),这些突变会使 p53 的肿瘤抑制功能失活,并与 B 细胞恶性肿瘤对化疗的耐药性有关。 该细胞系在 90% RPMI 1640 培养基 + 10% 热灭活 FBS 中培养。

JVM-3 适用于 B-PLL 相关研究,包括成熟 B 细胞白血病生物学研究、TP53 突变相关耐药性研究、BCR 信号通路分析、靶向治疗(BTK 抑制剂、维奈托克、 CD20靶向抗体)的评估,以及针对B细胞恶性肿瘤的药物筛选。该细胞系还用于B细胞白血病亚型的比较研究,并可作为免疫缺陷宿主中的异种移植模型。

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

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。
