01General information

Description

BV-173 細胞系源自一名經診斷為費城染色體陽性(Ph+)慢性骨髓性白血病(CML)患者的外周血,於 1980 年建立。 該細胞系最為人稱道之處在於其 Ph+ 狀態,這表明存在一種涉及第 9 號染色體與第 22 號染色體之間易位的特定染色體異常。 這種轉位常被稱為費城染色體,會產生 BCR-ABL 融合基因,這是一種關鍵的分子標誌,透過促進白血病細胞的增殖與存活,驅動 CML 的病理機制。

BV-173 細胞廣泛應用於血液學研究,作為研究 CML 細胞與分子機制的模型,特別是在藥物抗藥性以及細胞對酪胺酸激酶抑制劑(TKIs)的反應方面——這些抑制劑以 BCR-ABL 融合蛋白為標靶。 該細胞系在臨床前研究中發揮了關鍵作用,用於評估新的治療策略並深入理解 CML 的生物學特性。BV-173 展現出骨髓系細胞的典型特徵,常被用於研究因 BCR-ABL 致癌基因而在 CML 中失調的訊號傳導路徑。

每週 2 至 3 次
Post-thaw recovery
請讓細胞有至少 48 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。
