01General information

Description

EFO-27 細胞系是一種源自中度分化漿液性乳頭狀腺癌的人類卵巢癌模型。該細胞系是從一名晚期卵巢癌患者的實性大網膜轉移灶中建立而來。 EFO-27 屬於一系列源自卵巢腫瘤的細胞系之一,該系列細胞系旨在探索卵巢癌細胞增殖的激素調控機制。 據報導,在早期傳代階段,EFO-27 為非整倍體,其模態染色體數超過 100,顯示出高度的染色體不穩定性,這是高分化度漿液性卵巢癌的一項常見特徵。

EFO-27 細胞在體外呈現上皮樣形態,並已被證實在單層培養中會形成穹頂狀的多細胞結構,這種表型有時與主動離子轉運及緊密連接的形成有關。 在無血清培養基中,EFO-27 的增殖會受到性腺刺激激素(尤其是人絨毛膜性腺刺激素 [hCG] 和卵泡刺激素 [FSH])的刺激,這表明該細胞保留了功能性的激素受體訊號傳導途徑。 這種反應性突顯了促性腺激素訊號傳導在促進卵巢癌腫瘤生長與進展中的潛在作用,並支持將 EFO-27 作為研究卵巢癌生物學中激素驅動機制的重要模型。

EFO-27 亦已被納入主要的多組學資料集,例如《癌症細胞系百科全書》(CCLE)和 COSMIC,其基因組特徵有助於藥物敏感性圖譜繪製及腫瘤亞型分類。 這些資料集提供了更多層面的資訊,包括基因表達、拷貝數變異及突變圖譜,使 EFO-27 成為卵巢癌臨床前研究中特徵明確的資源。

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。
