01General information

Description

NUGC-3 是一种源自一名低分化腺癌患者原发肿瘤的人胃癌细胞系。该细胞系是研究胃癌的重要模型,胃癌作为一种恶性肿瘤,其特征是异质性高,且晚期预后不良。 NUGC-3 细胞被广泛应用于癌症生物学研究,特别是在肿瘤进展、转移以及针对胃癌的新型治疗药物评估等领域。

NUGC-3 细胞呈现上皮形态,在标准细胞培养条件下呈贴壁生长。这些细胞携带与胃腺癌相关的遗传和分子改变,包括关键致癌基因和肿瘤抑制基因的突变。 研究人员利用该细胞系研究了对肿瘤生长至关重要的信号传导通路,例如 EGFR、HER2 及其他受体酪氨酸激酶通路的失调,以及在癌症侵袭和转移中起作用的上皮-间质转化(EMT)过程。

鉴于胃癌常对标准治疗产生耐药性,该细胞系也适用于化疗耐药性研究。NUGC-3细胞被用于药物筛选试验,以测试细胞毒性药物、靶向治疗及联合治疗的疗效。 此外,该细胞系还为探索肿瘤-基质相互作用以及肿瘤微环境在胃癌进展中的作用提供了强大的平台。因此,NUGC-3 仍是推动胃癌研究和治疗药物开发的重要资源。

Subculturing
常规粘附细胞培养:吸出粘附细胞中的旧培养基,并用 PBS 冲洗以去除残留的培养基。吸出 PBS 后,根据培养皿大小加入适量的胰蛋白酶/EDTA 溶液(如 T25 烧瓶 1 毫升,T75 烧瓶 3 毫升),室温或 37°C 孵育直至细胞分离(5-10 分钟)。在显微镜下观察分离情况,必要时轻轻拍打容器以释放细胞。细胞分离后,加入完全培养基以灭活胰蛋白酶/EDTA,轻轻重悬细胞,然后将等分的细胞悬浮液转移到装有新鲜培养基的新培养皿中。将培养皿放入温度为 37°C、二氧化碳浓度为 5%的培养箱中,每 2-3 天更换一次培养基。

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。
