01General information

Description

MOLT-3 是一种人类 T 淋巴细胞系,来源于一名 19 岁男性急性淋巴细胞白血病(ALL)患者的外周血,特别是在之前化疗后复发期间。该细胞系由 J. Minowada 博士保存,与 MOLT-4 细胞系密切相关,两者均来自同一患者。MOLT-3 细胞被广泛用于免疫系统疾病、免疫学和免疫肿瘤学研究,是研究 T 细胞白血病和各种治疗的免疫反应的重要模型。

作为悬浮细胞系,MOLT-3 表现出典型的 T 细胞标记,包括 CD5(97%)和 CD7(97%)以及 CD1 和 CD4 的高表达。该细胞系的另一个特点是末端脱氧核苷酸转移酶(TdT)活性升高,这通常与未成熟淋巴细胞有关。MOLT-3 对研究 T 细胞分化、受体信号转导和细胞凋亡很有价值,尤其是在 T 细胞急性淋巴细胞白血病(T-ALL)方面。由于其生长特性和良好的抗原表达特性,它经常被用于白血病治疗的药物筛选和治疗研究。

此外,MOLT-3 细胞不产生免疫球蛋白,也不含有可检测到的 Epstein-Barr 病毒(EBV),因此是研究 T 细胞特异性通路的绝佳模型,不会受到 B 细胞特性的干扰。该细胞系对各种实验操作的反应进一步提高了其在免疫肿瘤学中的应用,尤其是在探索针对 T 细胞恶性肿瘤的潜在治疗干预方面。

05Expression and susceptibility

Antigen expression
CD1(+)、CD5(+)、CD7(+)、CD11a(+)(格林伯格等人,1988 年)。

06Handling and culture

Culture medium
RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加热灭活的 10% FBS
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。
Seeding density
0.5至1×10⁵个细胞/毫升
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。
