01General information

Description

SW626 是一種從一名患有卵巢漿液性囊腺癌的成年患者所建立的人類卵巢癌細胞系。該細胞系已被廣泛用作上皮性卵巢癌(EOC)的模型,特別是用於研究高分化漿液性癌的腫瘤生物學、藥物反應及分子異質性。 從組織學角度來看,SW626 細胞系保留了與其漿液性腺癌起源相符的特徵,並在異種移植至免疫缺陷小鼠時展現出致瘤潛能,形成能重現原發性腫瘤特徵的實體腫瘤。

SW626 的基因組分析顯示出卵巢癌中常見的變異,包括 TP53 和 PI3K/AKT 等關鍵調控路徑的紊亂。 分子分析顯示,SW626 攜帶代表高分化度漿液性卵巢癌的染色體異常及基因表達模式,使其成為研究致癌訊號傳導、治療弱點及抗藥性機制的相關模型。 該細胞系已被納入大規模癌症基因組學計畫,在其中為藥物篩選平台及其他卵巢癌模型的比較研究做出貢獻,有助於界定分子亞型並為精準腫瘤學策略提供依據。

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。
