01General information

Description

TE10 細胞系屬於 TE 系列,該系列是由日本建立的一組食道癌模型,具體源自一例分化良好的食道鱗狀細胞癌。 TE10 細胞以其上皮狀形態及單層培養特性著稱。這些細胞源自未曾接受過放射治療的原發性病灶,因此能代表未經治療的腫瘤生物學特徵。

TE10 展現出數種與食道癌進展相關的關鍵基因變異。這些變異包括 c-erbB 基因的擴增與過度表達、int-2 和 hst-1 原癌基因的共同擴增,以及 TGF-α 和 EGF-R 等生長因子的調控失調。 這些分子特徵使 TE10 成為研究參與腫瘤生長之途徑(例如表皮生長因子受體 [EGFR] 訊號傳導軸)的寶貴模型。此外,該細胞系亦被用於研究對標靶療法及化療藥物的反應,從而闡明藥物抗性的機制。

由於 TE10 細胞具有在軟瓊脂中形成集落以及展現錨定獨立生長的能力,因此也常被用於侵襲與遷移實驗。這些特性凸顯了其在探索轉移分子驅動因子方面的實用價值。 該細胞系在腫瘤生物學與藥理學實驗中表現穩定,使其成為轉譯癌症研究的重要工具,特別是針對食道鱗狀細胞癌的治療策略開發。

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。
