01General information

Description

SW1271 细胞系是一种人类小细胞肺癌(SCLC)模型,来源于一名成年患者。它的特点是具有典型的 SCLC 神经内分泌表型,并显示出与治疗敏感性和耐药性相关的分子特征。在对包括 SW1271 在内的 SCLC 细胞系进行的表观基因组范围甲基化综合分析中,该细胞系表现出的特定 DNA 甲基化模式与对几类抗癌药物的化疗敏感性相关。这些药物包括极光激酶抑制剂、CDK抑制剂和DNA损伤剂。在 SW1271 和其他 SCLC 模型中,TREX1、SLFN11、CEP350 和 KDM1A 等关键基因的甲基化状态与药物反应的改变有关,这表明表观遗传调节是疗效的决定因素。

此外,SW1271 还被用于综合基因组学和表观基因组学研究,以了解 SCLC 亚型特异性的脆弱性。该细胞系与其他代表不同 SCLC 转录亚型(ASCL1、NEUROD1、POU2F3 和 YAP1)的细胞系一起,有助于描述该疾病的异质性。SW1271 的甲基化图谱有助于我们了解影响基因表达和药物反应的调控机制,包括肿瘤抑制基因的抑制和系特异性转录因子的失调。这些见解使 SW1271 成为研究 SCLC 表观遗传驱动通路以及鉴定潜在生物标记物和治疗靶点的宝贵模型。

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

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。
