01General information

Description

WEHI-3B 細胞系是一種小鼠白血病細胞系,廣泛用作研究骨髓單核細胞分化及白血病病理生理學的模型。 該細胞株最初源自 BALB/c 小鼠,具有骨髓前體細胞的特徵,在造血分化與調控的研究中發揮了關鍵作用。 WEHI-3B 細胞系對於研究生長因子對白血病細胞的影響尤為重要,並已被用於評估包括集落刺激因子在內的各種物質的造血活性。

該細胞系不僅在白血病研究中具有重要意義,更因其能在特定實驗條件下分化為巨噬細胞和粒細胞,因而成為研究這兩種細胞功能的工具。 利用 WEHI-3B 細胞進行的研究,有助於更深入理解細胞分化所涉及的分子途徑,以及基因變異對白血病進展的影響。 此外,WEHI-3B 細胞系亦被用於檢測單核細胞集落刺激因子(M-CSF)及粒細胞-巨噬細胞集落刺激因子(GM-CSF)的生物活性,凸顯了其在血液學研究領域中的多功能性與實用價值。

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。
Seeding density
1 × 105 個細胞/毫升
Fluid renewal
每週 2 至 3 次
Post-thaw recovery
解凍後,請讓細胞有至少 24 小時的時間從冷凍過程中恢復。
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。
