01General information

Description

NUGC-3 是一種源自一名低分化腺癌患者原發性腫瘤的人類胃癌細胞系。該細胞系是研究胃癌的重要模型,胃癌是一種以高度異質性及晚期預後不良為特徵的惡性腫瘤。 NUGC-3 細胞廣泛應用於癌症生物學研究,特別是在腫瘤進展、轉移以及針對胃癌之新型治療藥物評估等領域。

NUGC-3 細胞呈現上皮形態,並在標準細胞培養條件下呈貼壁生長。這些細胞攜帶與胃腺癌相關的遺傳及分子改變,包括關鍵致癌基因與腫瘤抑制基因的突變。 研究人員利用此細胞系,探究對腫瘤生長至關重要的訊號傳導路徑,例如 EGFR、HER2 及其他受體酪胺酸激酶路徑的失調,以及在癌症侵襲與轉移過程中扮演重要角色的上皮-間質轉化(EMT)過程。

由於胃癌常對標準治療產生抗藥性,此細胞系亦適用於化療抗藥性研究。NUGC-3 細胞被運用於藥物篩選試驗中,用以測試細胞毒性藥物、標靶治療及聯合治療的療效。 此外,該細胞系還為探索腫瘤-基質相互作用以及腫瘤微環境在胃癌進展中的作用提供了穩健的研究平台。因此,NUGC-3 仍是推動胃癌研究與治療開發的重要資源。

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。

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。
