01General information

Description

Kasumi-1 細胞系源自一名 7 歲日本男童的外周血,該男童罹患急性骨髓性白血病(AML),具體為 FAB M2 亞型,且是在骨髓移植後復發期間所取得。 該細胞系對於研究血液惡性腫瘤的研究人員而言是一項寶貴資源,特別是針對涉及 t(8;21) 染色體易位的相關研究。 這種轉位會導致 AML1-ETO 融合基因的形成,該基因是某些亞型 AML 的關鍵因子。因此,Kasumi-1 細胞成為研究 AML 分子機制及測試潛在治療方法的重要模型。

Kasumi-1 細胞兼具髓系和巨噬細胞系的特徵,使其在髓系分化研究中尤為有用。 當這些細胞與佛波酯 12-肉豆蔻酸酯 13-乙酸酯(TPA)共同培養時,可被誘導分化為巨噬細胞樣細胞,從而提供了一個穩健的系統,用於探索參與髓系譜系決定與分化的途徑。 這種分化能力增強了 Kasumi-1 細胞在針對急性骨髓性白血病(AML)生物學以及更廣泛的骨髓系細胞發育過程之研究中的應用價值。

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.

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。
