01General information

Description

L-591 细胞系是源自霍奇金病(特别是结节性硬化亚型)患者的多个肿瘤细胞系之一。L-591 细胞系是霍奇金淋巴瘤细胞系(包括 L-428 和 L-540)的一部分,它的建立有助于加深人们对这种血液恶性肿瘤的认识。L-591 细胞具有非整倍体特征,表现出各种染色体结构和数目异常,这表明它们是肿瘤细胞。该品系具有独特的染色体模式和体外增殖能力,是研究霍奇金淋巴瘤细胞机制的可靠模型,因此特别具有研究价值。

L-591 细胞的一个显著特点是其免疫表型。这种细胞表达与 T 细胞相关的 Ia 类抗原和受体,但缺乏其他造血系(如骨髓细胞、单核细胞和巨噬细胞)的典型标记。值得注意的是,L-591 细胞不产生表面或胞质免疫球蛋白,也不表现出 Epstein-Barr 病毒(EBV)特异性抗原,如 EBNA。免疫球蛋白和 EBV 抗原的缺失使 L-591 有别于其他 EBV 阳性的霍奇金淋巴瘤细胞系,并突显了它在探索霍奇金淋巴瘤病理特异性(与 EBV 感染无关)方面的作用。

L-591 细胞系在形态上类似于霍奇金淋巴瘤特有的里德-斯特恩伯格(RS)细胞和霍奇金(H)细胞。这些细胞在霍奇金病的研究中起着至关重要的作用,是了解该病发病机制和确定潜在治疗靶点的模型。L-591 的独特性及其在实验室环境中的广泛应用,使其成为研究霍奇金淋巴瘤的重要工具,极大地丰富了围绕这种复杂恶性肿瘤的知识体系。

05Handling 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 10% FBS、1 mM 丙酮酸钠和 1% NEAA
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
3×10⁵/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.

06Quality 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。
