01General information

Description

TPC-1 細胞系源自乳頭狀甲狀腺癌(PTC),廣泛用作研究甲狀腺癌分子機制的研究模型。該細胞系的顯著特徵在於攜帶 RET/PTC1 重排,這是 PTC 的標誌性遺傳變異。 RET/PTC1 融合基因會導致 RET 酪胺酸激酶訊號傳導持續活化,進而驅動致癌過程,例如促進細胞增殖、存活及分化。此遺傳特徵使 TPC-1 成為理解甲狀腺致癌機制及評估標靶治療的寶貴工具。

TPC-1 源自一例分化良好的甲狀腺腫瘤,因此保留了上皮細胞的特徵,並展現出與甲狀腺分化相關的特徵,包括甲狀腺球蛋白的產生。 TPC-1 的訊號傳導路徑已受到廣泛研究,特別是 RET/PTC1 下游被活化的 MAPK 及 PI3K/AKT 路徑。這些路徑對甲狀腺腫瘤的進展至關重要,並代表治療干預的目標。

除了其遺傳和細胞特徵外,TPC-1 亦已被應用於體外及體內模型,用以探究 RET 抑制劑及其他標靶治療的有效性。其特徵明確的遺傳背景以及對藥理學製劑的反應性,使其成為甲狀腺癌轉譯研究中至關重要的模型。 將 TPC-1 與其他甲狀腺癌細胞系進行比較的研究,亦突顯了其在識別甲狀腺癌亞型之共同與獨特分子特徵方面的作用,有助於開發個人化治療策略。

05Handling 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 10% FBS 及 4.5 g/L 葡萄糖
Dissociation reagent
Accutase
Subculturing
從貼壁細胞中移除舊培養基,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶使用3-5毫升PBS,T75培養瓶則使用5-10毫升。 接著,用 Accutase 完全覆蓋細胞,T25 培養瓶使用 1–2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8–10 分鐘,使其脫附。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。
Fluid renewal
每週 2 至 3 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.

06Quality 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。
