01General information
- Description
GES-1 是一種人類胃上皮細胞系,常被用於以胃黏膜為研究重點的實驗,特別是在探討胃部疾病、發炎及細胞毒性反應的研究中。這些細胞源自正常胃組織,可作為體外模型,用於探究環境毒素、藥物及病原體對胃上皮細胞的影響。
利用 GES-1 進行的一項重要研究領域,是探討環境污染物(例如奈米塑膠)對人類胃細胞的細胞毒性作用。 例如,研究顯示聚苯乙烯奈米塑膠(PS-NPs)會透過內吞作用進入 GES-1 細胞,進而誘發自噬、凋亡及細胞增殖減緩等細胞壓力反應。 研究發現這些顆粒會積聚於囊泡、自噬體及溶酶體中,顯示其已被胃上皮細胞內化,並具有細胞毒性潛力。 此外,研究顯示,抑制 RhoA/F-肌動蛋白訊號傳導路徑等途徑,可減少這些奈米塑膠的內化,有助於理解支配細胞攝取及對異物反應的分子機制。
GES-1 細胞亦被用於研究各種化合物對胃部損傷的保護作用。例如,傳統藥用植物「齒葉蓼」(Fallopia denticuta)已被證實能保護 GES-1 細胞免受乙醇誘導的損傷。 研究顯示,該植物的萃取物能促進 GES-1 細胞的增殖,並減輕氧化壓力與發炎反應——這兩者正是導致胃潰瘍發生的關鍵因素。這使得 GES-1 細胞成為胃部健康研究中,探索細胞毒性機制與潛在保護性治療方案的重要工具。

- 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
透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。
為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。
- Freeze medium
- 作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
- Storage conditions
若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。
- Shipping conditions
冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。

09Legal and safety
- Safety precautions
- 若計劃將低溫試管存放在液態氮中以供日後解凍,必須嚴格遵守相關安全措施。 必須穿戴適當的防護手套和防護服,且在將冷凍樣本移入或移出液氮罐時,必須佩戴口罩或安全護目鏡。此舉旨在降低因取出時冷凍試管可能發生爆炸而導致受傷的風險,此類爆炸可能造成尖銳碎片飛濺。
