01General information
- Description
HEYA8 細胞系是人類卵巢癌的一種特徵明確的模型,最初由一名患有乳頭狀囊腺癌的患者建立。該細胞系以其侵襲性生長和轉移潛能而著稱,常被用於涉及卵巢癌病理生理學及治療研究。 HEYA8 細胞因其表達白細胞介素-8(IL-8)——一種與癌症進展相關的趨化因子——而受到廣泛研究。IL-8 作為一種自分泌生長因子,能促進細胞增殖、血管生成及腫瘤侵襲性。 值得注意的是,在 HEYA8 細胞中,高水平的 IL-8 表達與腫瘤生長加速及微血管密度增加呈正相關。透過 IL-8 載體進行的實驗性轉染顯示,增強 IL-8 表達可顯著促進腫瘤增殖,而中和抗體則能抑制此種生長。
HEYA8 細胞亦被用於研究卵巢癌對各種應激條件(例如缺氧)的反應。 缺氧會透過涉及 PI3K/Akt 和 p38 MAPK 的途徑,觸發這些細胞中 IL-8 的過度表達。這些途徑的活化會透過 AP-1 和 NF-κB 等因子增強 IL-8 基因的轉錄,有助於腫瘤適應低氧環境,並促進其存活與轉移潛能。 因此,目前正探索針對 PI3K 和 p38 MAPK 路徑的抑制劑,作為減輕 HEYA8 細胞侵襲性特徵並抑制腫瘤進展的潛在策略。

- 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.
05Quality 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。

07Legal 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。
- Warranty
在 Cytion,我們對產品的品質與存活率提供保障。 我們保證,自本公司設施出貨後 60 天內,我們的細胞在培養開始時仍具存活能力。 我們保證所有材料均符合 分析證明書及/或產品說明書中所載的規格。
