01General information

Description

WEHI-3 細胞系是一種小鼠白血病細胞系,具體源自 BALB/c 品系。該細胞系最初是從一隻小鼠身上發現的自發性骨髓單核細胞性白血病建立而來。 該細胞系被廣泛用作研究髓系分化與免疫反應的模型,特別是白血病進展的潛在機制,以及白血病細胞對各種治療的反應。WEHI-3 細胞能夠產生白細胞介素-3(IL-3),並常被用作該細胞因子的來源進行研究。

在實驗室環境中,WEHI-3 細胞已被用於評估各種化合物的分化潛能,以及調節造血系統的生物活性。這些細胞在理解基因表達的改變如何影響髓系細胞方面發揮了關鍵作用,並成為開發針對髓系白血病治療策略的重要工具。 該細胞系亦可透過移植至易感小鼠品系,用於建立小鼠疾病模型,從而進行腫瘤進展及抗癌藥物療效的研究。

06Handling and culture

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Subculturing
可透過添加或更換新鮮培養基來維持細胞培養。起始培養濃度應為 5 × 10⁵ 個細胞/毫升,並維持在 3 × 10⁵ 至 1 × 10⁶ 個細胞/毫升之間。貼壁細胞可透過刮取方式回收。
Fluid renewal
每週 2 至 3 次
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。
