01General information

Description

WERI-Rb-1 细胞系来源于视网膜母细胞瘤,这是一种罕见的视网膜恶性肿瘤,通常在儿童早期发病。建立该细胞系的目的是为视网膜母细胞瘤生物学研究提供一个一致的、可复制的模型,从而深入了解这种癌症的遗传、分子和细胞机制。WERI-Rb-1 细胞在研究视网膜母细胞瘤的病理生理过程和潜在治疗靶点方面具有重要价值,因此在肿瘤研究中尤为重要。

WERI-Rb-1 细胞具有视网膜母细胞瘤的典型特征,包括神经元标记的表达和形成类似 Flexner-Wintersteiner rosettes 的细胞聚集的能力,这是视网膜母细胞瘤组织学的标志。这些细胞被广泛用于研究癌基因和抑癌基因在癌症发展中的作用,重点研究 RB1 基因,该基因的突变在视网膜母细胞瘤的病因学中起着关键作用。此外,WERI-Rb-1 还是评估化疗药物和新型给药系统的重要工具,旨在改善视网膜母细胞瘤患者的治疗效果。

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 10% FBS 和 0.01 mg/mL 胰岛素
Subculturing
通过上下吸取操作轻柔匀化烧瓶中的细胞悬液,随后取代表性样本测定每毫升细胞密度。用新鲜培养基将悬液稀释至1×10⁵细胞/毫升浓度,并将调整后的悬液分装至新烧瓶中进行后续培养。
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
作为冷冻保存培养基,我们使用 50% 基础培养基 + 40% FBS + 10% DMSO 或 CM-1(Cytion 目录号 800100),其中包括优化的渗透保护剂和代谢稳定剂,以促进恢复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。
