01General information

Description

OCI-LY1是一种源自成人患者的人类弥漫性大B细胞淋巴瘤(DLBCL)细胞系。它属于DLBCL的生发中心B细胞(GCB)亚型,其分子特征与正常生发中心B细胞高度相似。 基因表达谱分析支持该分类:研究表明OCI-LY1与GCB-DLBCL聚类,该亚型通常预后优于活化B细胞型(ABC)DLBCL。该细胞系维持B细胞标志物表面表达,并呈现DLBCL典型特征,包括高增殖率及符合侵袭性淋巴瘤行为的染色体异常。

在DLBCL遗传异质性与致癌信号通路研究中,OCI-LY1已成为重要模型。基因组研究发现该细胞系存在反复突变,包括调控染色质重塑、细胞凋亡及B细胞受体信号通路的基因改变。 值得注意的是,该细胞系不存在NF-κB通路的持续激活状态,这一特征使其区别于ABC-DLBCL细胞系,并与GCB分子亚型相吻合。这使其特别适用于研究独立于NF-κB信号通路的淋巴瘤发生机制及药物反应机制。 此外,该细胞系已被用于免疫遗传学研究(包括HLA分型),这对探索肿瘤免疫原性及癌症免疫治疗中的新抗原呈递至关重要。

在培养条件下,OCI-LY1细胞表现出悬浮生长特性,适用于体外及体内实验(包括异种移植研究)。其维持的克隆型免疫球蛋白重排证实源自单一B细胞克隆。凭借稳定的生长特性和遗传谱系,该细胞系成为靶向治疗临床前测试的可靠工具,尤其适用于表观遗传调节剂、PI3K通路抑制剂及诱导DNA损伤应答药物的研究。

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。
