01General information

Description

CASP-2-1 細胞系是一種基因定義明確的小鼠前列腺上皮細胞系,是透過組織重組方法,從一種雄激素依賴性原發性腫瘤開發而來。 CASP-2-1 屬於 CASP 系列前列腺癌模型之一,該系列模型是透過將分離的胚胎泌尿生殖竇間質與前列腺腫瘤上皮細胞進行重組而建立,從而實現體內導管形成並驗證上皮細胞特性。 CASP-2-1 細胞表達 E-鈣黏蛋白等上皮標記物,並在至少 30 代傳代過程中展現穩定的增殖能力,其致瘤能力透過體外錨定獨立生長及小鼠原位注射後的腫瘤形成得到一致驗證。

CASP-2-1 的顯著特徵在於其保留了對雄激素的反應性。與其他幾條 CASP 細胞系不同,CASP-2-1 的生長依賴於雄激素,且在二氫睪酮(DHT)存在下,其雄激素反應性啟動子元件會被激活。 該細胞系在 mRNA 和蛋白質層面均表達野生型雄激素受體(AR),且未檢測到 AR 突變。此外,CASP-2-1 對 Pten 基因呈雜合狀態,並顯示中等水平的磷酸化 Akt(p-Akt),表明 PI3K/Akt 訊號傳導路徑已部分活化。 這些特徵使 CASP-2-1 成為剖析前列腺癌中 AR 訊號傳導與 Pten 依賴性致癌途徑之間相互作用的寶貴模型,特別是在早期或雄激素敏感性疾病的情境下。

06Handling and culture

Incubation atmosphere

37°C,5% CO₂,加濕環境。

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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.

  7. Follow the procedure described under Post-Thaw Recovery

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加上 10% 的二甲基亞砜(DMSO),以確保解凍後的細胞存活率達到適當水準。
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。
