01General information

Description

NOMO-1 細胞系源自一名被診斷為急性單核細胞性白血病(AML-M5a)的 31 歲女性患者。該細胞系呈現前單核細胞特徵,使其成為研究單核細胞性白血病及分化的可靠模型。 NOMO-1 細胞對分化誘導劑(如佛波酯類,例如 12-o-十四碳酰基佛波酯-13-乙酸酯或 TPA)具有反應性,可促使細胞成熟為巨噬細胞樣細胞。 分化後,這些細胞會增加纖維連接蛋白等標記物的表達,並分泌白細胞介素 IL-1α 和 IL-1β,這些物質對於免疫反應和發炎途徑至關重要。

這些細胞在研究凝血與纖溶系統方面也扮演著關鍵角色。NOMO-1 細胞會分泌組織因子(TF)、纖溶酶原活化劑(PA)及纖溶酶原活化劑抑制劑(PAI),其分泌水平受分化誘導劑調控。 TPA 處理可增強 TF 和 PA(尤其是尿激酶型纖溶酶原激活劑 [uPA])的產生,同時也增加 PAI 的分泌,這表明 NOMO-1 對於理解白血病中的止血與血栓形成機制具有重要意義。

從遺傳學角度來看,NOMO-1 細胞攜帶 t(9;11)(p22;q23) 易位,導致產生 MLL-AF9 融合基因,這是某些急性骨髓性白血病(AML)亞型的標誌性特徵。 這種易位會透過擾亂與造血分化及增殖相關的基因表達程序,從而驅動白血病發生。由於存在此種易位,NOMO-1 成為探索 MLL 重排型白血病及評估標靶治療的重要工具。

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。
