01General information

Description

SU-DHL-8 是一種源自成人患者的人類彌散性大 B 細胞淋巴瘤(DLBCL)細胞系。 該細胞系屬於 DLBCL 的活化 B 細胞樣(ABC)亞型,其特徵為 NF-κB 訊號傳導路徑的持續活化,且相較於生發中心 B 細胞樣(GCB)亞型,通常預後較差。 在形態學上,SU-DHL-8 細胞在懸浮液中以大型、鬆散黏附的聚集体形式生長,這與 B 細胞淋巴瘤的表型一致。

分子特徵分析顯示,SU-DHL-8 攜帶與 ABC-DLBCL 常見相關的突變,包括影響 BCR 和 NF-κB 訊號傳導路徑的變異。 透過次世代定序進行的基因組分析及基因表達分析,已發現 JAK/STAT 及 BCL2 相關的抗凋亡訊號傳導等路徑的活性升高。 該細胞系亦被納入多項大規模藥物基因組學研究及癌症模型資料庫,並被用於探索藥物敏感性,特別是針對激酶抑制劑和蛋白酶體靶向藥物。 這些特徵使 SU-DHL-8 成為研究 ABC 型 DLBCL 分子病理機制與治療弱點的代表性且極具價值的模型。

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

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。
