01General information

Description

MUM2B 細胞系是一種源自葡萄膜黑色素瘤肝轉移灶的轉移性葡萄膜黑色素瘤模型。該細胞系廣泛應用於眼科腫瘤學研究,用於探究轉移性葡萄膜黑色素瘤的侵襲性與侵襲特徵。 與原發性葡萄膜黑色素瘤細胞系不同,MUM2B 展現出更強烈的轉移行為,使其成為理解晚期黑色素瘤進展及治療抗藥性的關鍵工具。

研究顯示,MUM2B 細胞保留了 S-100、HMB-45 及 Melan-A 等關鍵黑色素瘤標記物,證實其源自黑色素細胞。此外,該細胞系的特徵在於能於體外模擬血管生成模式,此現象與腫瘤的侵襲性及轉移潛能有關。 MUM2B已被用於探究驅動黑色素瘤進展的分子機制,包括細胞凋亡抵抗途徑及線粒體功能失調的作用。該細胞系會以 p53 獨立的方式對 NOXA 等特定細胞凋亡誘導劑產生反應,凸顯其在探索針對細胞凋亡抵抗性腫瘤之治療策略方面的實用價值。

利用 MUM2B 進行的研究,對識別轉移性黑色素瘤的潛在治療靶點做出了重大貢獻。 研究顯示,該細胞系對創新化合物(如 γ-分泌酶抑制劑(GSI))具有敏感性;此類化合物能選擇性地誘導黑色素瘤細胞凋亡,同時不損害正常黑色素細胞。這些發現強調了 MUM2B 作為測試新型治療藥物及深化對轉移性葡萄膜黑色素瘤生物學理解之關鍵模型所扮演的重要角色。

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.

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。
