01General information
- Description
GES-1 是一种人类胃上皮细胞系,常用于胃粘膜研究,特别是胃病、炎症和细胞毒性反应的研究。这些细胞来源于正常胃组织,是研究环境毒素、药物和病原体对胃上皮细胞影响的体外模型。
利用 GES-1 进行研究的一个重要领域是研究纳米塑料等环境污染物对人类胃细胞的细胞毒性作用。例如,聚苯乙烯纳米塑料(PS-NPs)已被证明可通过内吞作用进入 GES-1 细胞,诱导自噬、细胞凋亡和细胞增殖减少等细胞应激反应。研究发现,这些颗粒会积聚在囊泡、自噬体和溶酶体中,这表明它们在胃上皮细胞内被内化并具有细胞毒性潜力。此外,研究还表明,抑制 RhoA/F-actin 信号通路等途径可减少这些纳米塑料的内化,这有助于了解细胞摄取和对外来微粒反应的分子机制。
GES-1 细胞还用于研究各种化合物对胃损伤的保护作用。例如,传统药用植物Fallopia denticuta对GES-1细胞乙醇引起的损伤具有保护作用。研究表明,这种植物的提取物能增强 GES-1 细胞的增殖,减少氧化应激和炎症,而氧化应激和炎症是导致胃溃疡发生的关键因素。这使得 GES-1 成为胃健康研究中探索细胞毒性机制和潜在保护疗法的重要工具。

- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
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.
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.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
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.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
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.
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。

09Legal and safety
- Safety precautions
- 计划将低温样品储存在液氮中以便将来解冻时,必须遵守严格的安全措施。在将冷冻样本移入或移出液氮罐时,必须穿戴适当的防护手套和防护服,并使用面罩或安全护目镜。这样做是为了降低在移出时因冷冻样品爆炸而造成伤害的风险,因为爆炸可能导致锋利的碎片飞溅。
