01General information

Description

8305C 細胞系是一種源自未分化甲狀腺未分化癌的人類甲狀腺癌細胞系。這些細胞的特徵在於其侵襲性生長行為及分化程度低,這正是甲狀腺未分化癌的典型特徵。 該細胞系保留了若干與甲狀腺癌病理生理學研究相關的關鍵特徵,包括基因表達譜的改變以及在甲狀腺癌發生過程中起關鍵作用的訊號傳導路徑。

利用 8305C 細胞系進行的研究已證實,該細胞系在探索甲狀腺癌進展、治療抗藥性及轉移背後的分子機制方面具有實用價值。具體而言,此細胞系已被用於研究各種化療藥物及標靶治療的療效,使其成為臨床前藥物測試的寶貴模型。 此外,8305C 亦被應用於探討遺傳及表觀遺傳修飾在甲狀腺癌中所扮演角色的研究,為這種侵襲性癌症提供了潛在治療標靶與生物標記物的見解。

由於源自高惡性度腫瘤,8305C 細胞系在甲狀腺癌研究中扮演重要工具的角色,特別是在旨在理解未分化甲狀腺癌的侵襲性行為,以及開發有效治療策略的研究中。

05Handling and culture

Culture medium
EMEM(MEM Eagle),含 2 mM L-谷氨醯胺,含 2.2 g/L NaHCO₃,含 EBSS(Cytion 產品編號 820100a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS 和 1% NEAA
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。
