01General information

Description

JVM-3 是一種從一名 73 歲白人男性患者的外周血中建立的人類 B 細胞前淋巴細胞白血病(B-PLL)細胞系。 該細胞系以懸浮方式生長,呈現單個或鬆散簇狀的淋巴母細胞樣細胞形態,是研究 B-PLL(一種罕見且具侵襲性的成熟 B 細胞白血病)的廣泛應用模型。 JVM-3 攜帶 TP53 突變(p.Pro1435Leu 雜合突變及 p.Lys601Asn 雜合突變),這些突變會使 p53 的腫瘤抑制功能失活,並與 B 細胞惡性腫瘤對化療的抗藥性有關。 該細胞系以 90% RPMI 1640 培養基 + 10% 熱滅活胎牛血清 (FBS) 進行培養。

JVM-3 適用於 B-PLL 研究,包括成熟 B 細胞白血病生物學研究、TP53 突變相關藥物抗性研究、BCR 訊號傳導路徑分析、標靶療法評估(BTK 抑制劑、維奈托克、 CD20靶向抗體),以及針對B細胞惡性腫瘤的藥理學藥物篩選。此外,該細胞系亦可用於B細胞白血病亞型的比較研究,並作為免疫功能低下宿主的異種移植模型。

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

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。
