01General information

Description

MUG-Chor1 細胞系是一種特徵明確的體外模型,源自一名高加索裔女性患者的復發性骶尾部脊索瘤。 索瘤是一種罕見的惡性腫瘤,源自軸向骨骼沿線的脊索殘餘組織。MUG-Chor1 透過機械與酶解方式對腫瘤組織進行解聚而建立,並在最佳化條件下進行培養以維持其生長。 該細胞系保留了脊索瘤的典型特徵,包括表達「短尾(brachyury)」——這是一種對脊索分化至關重要的轉錄因子,同時也是脊索瘤的診斷標記物。此外,MUG-Chor1 還表達細胞角蛋白、EMA、維曼汀及 S-100 蛋白,進一步證實其源自脊索瘤。

從遺傳學角度來看,MUG-Chor1 呈現出脊索瘤典型的染色體與分子變異,包括第 6 號染色體 6q27 位點的 brachyury (T) 基因座增益,以及涵蓋 CDKN2A/CDKN2B 基因座的 9p24.3-p13.1 區域缺失。 此外,該細胞系在 10q25.2 等位點(包含 PTEN)以及其他與腫瘤進展相關的區域亦呈現缺失。這些遺傳特徵使 MUG-Chor1 成為研究脊索瘤生物學及評估治療干預措施的寶貴工具。

MUG-Chor1 的生長速度緩慢,倍增時間為 7-10 天,這反映了脊索瘤的臨床行為特徵——該腫瘤雖以生長緩慢著稱,但具有局部侵襲性。 該細胞系在臨床前研究中扮演關鍵角色,包括已遴選出潛在治療藥物(如 EGFR 抑制劑)的藥物篩選研究。這些抑制劑在脊索瘤模型中已展現出降低細胞存活率及抑制腫瘤生長的功效,進一步凸顯 MUG-Chor1 對轉譯研究的實用價值。

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.

06Quality 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。
