01General information

Description

Panc 05.04 細胞系是一種胰管腺癌(PDAC)模型,是研究胰臟癌生物學及治療反應的寶貴資源。 Panc 05.04 源自人類胰臟癌,由於其與一種最具侵襲性且患者預後不佳的惡性腫瘤密切相關,因此在臨床前研究中成為一項關鍵工具。 該細胞系展現出與 PDAC 異質性相符的分子及基因組特徵,包括 KRAS、TP53 及其他在胰臟癌進展中普遍存在的驅動致癌基因中常見的突變。

作為「癌症細胞系百科全書」(CCLE)等大規模基因組計畫的一部分,Panc 05.04 已接受廣泛的特性分析,其中包含其基因表現、拷貝數變異及藥物敏感性的特徵描述。 值得注意的是,Panc 05.04 已針對多種抗癌藥物的藥理反應進行評估,從而提供其對化療及標靶治療之敏感性或耐藥性特徵的見解。

作為模型系統,Panc 05.04 有助於探究胰腺導管腺癌(PDAC)進展、化療耐藥性及腫瘤微環境相互作用背後的分子機制。它同時也提供了一個平台,用於測試旨在克服胰腺癌難治性的新興標靶療法與免疫治療策略。

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 15% FBS 及 20 µg/ml 人類重組胰島素
Dissociation reagent
胰蛋白酶-EDTA
Subculturing
針對常規貼壁細胞培養:將貼壁細胞中的舊培養基抽吸出來,並用PBS洗滌以去除殘留的培養基。抽吸掉PBS後,根據培養容器的大小加入適量的胰蛋白酶/EDTA溶液(例如:T25燒瓶為1毫升, T75 燒瓶則為 3 毫升),並於室溫或 37°C 下孵育,直至細胞脫落(5-10 分鐘)。 透過顯微鏡觀察細胞脫落狀況,必要時可輕輕敲擊培養容器以促使細胞脫落。細胞脫落後,加入完全培養基以失活胰蛋白酶/EDTA,輕輕重懸細胞,並將部分細胞懸液移入裝有新鮮培養基的新培養容器中。 將培養皿置於設定為 37°C 且含有 5% CO₂ 的培養箱中,並每 2-3 天更換一次培養基。
Fluid renewal
每週 1 至 2 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。
