01General information

Description

OE19 是一種源自巴雷特食道相關腺癌患者原發性腫瘤的人類食道腺癌細胞系。 該細胞系廣泛應用於食道癌相關研究,特別是針對巴雷特食道進展過程中腫瘤發生機制的探究。OE19 作為研究上消化道惡性腫瘤中腺癌發病分子機制、治療反應及抗藥性機制的模型。

OE19 細胞呈現上皮形態,並能在標準培養條件下附著生長。其特徵為具有食道腺癌典型的基因組變異與分子特徵,包括 HER2/neu(ERBB2)的過度表達——此為侵襲性腫瘤行為的標誌,亦是具臨床意義的治療靶點。 這使得 OE19 特別適合用於測試 HER2 靶向療法,例如單株抗體和酪胺酸激酶抑制劑。 此外,OE19 細胞還可用於探索對癌症進展至關重要的訊號傳導路徑,包括 MAPK/ERK 和 PI3K/AKT 路徑,以及免疫逃避機制與腫瘤微環境的相互作用。

在臨床前研究中,OE19 對於評估化療藥物、標靶療法以及旨在克服藥物抗藥性的新型聯合療法具有重要價值。 該細胞系亦被應用於異種移植模型中,以評估腫瘤的體內生長及治療功效。其分子特徵與巴雷特食道相關腺癌的關聯性,使 OE19 成為深化對這種棘手惡性腫瘤的理解與治療的重要資源。

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

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。
