01General information

Description

SNU-216 细胞系是一种人类胃癌模型,来源于一名中度分化腺癌患者的转移淋巴结。该细胞系是为研究胃癌生物学,特别是肿瘤抗原表达、基因突变和治疗反应而建立的胃癌模型小组的一部分。SNU-216 细胞在培养过程中呈现粘附生长模式,形成异质弥漫单层,细胞形态为圆椭圆形,细胞核与细胞质的比例较低。

基因分析表明,SNU-216 细胞系存在重大突变,包括 TP53 基因的改变。具体来说,第 6 号外显子发生了突变,这很可能会影响其抑癌基因的功能。此外,肿瘤抗原研究表明,SNU-216 表达高水平的癌胚抗原(CEA)和组织多肽抗原(TPA),但检测不到甲胎蛋白(AFP)。这些特点使该细胞系成为研究胃癌分子和遗传特征以及探索与肿瘤标志物相关的诊断和治疗应用的重要工具。

SNU-216 还被收录到《癌症细胞系百科全书》(CCLE)中,提供了大量基因组、转录组和药理学数据。该细胞系的分子特征已被用于预测对靶向疗法的敏感性,以及研究涉及受体酪氨酸激酶和 PI3K 信号转导的通路。将其纳入本资源强调了它作为胃癌研究和药物开发的临床前模型的重要性。

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。
