01General information

Description

Nthy-ori 3-1 細胞系是一種由正常人類甲狀腺濾泡上皮建立而成的非致瘤性模型。該細胞系透過 SV40 大 T 抗原(SV40T)實現永生化,因此能夠進行長期培養,且不會誘導其轉變為惡性表型。 Nthy-ori 3-1 細胞展現出甲狀腺上皮細胞的典型特徵,包括表達甲狀腺球蛋白和甲狀腺轉錄因子-1(TTF-1)等標記物,這些標記物對於甲狀腺特異性功能至關重要。 該細胞系是研究正常甲狀腺生物學、環境毒素的影響以及甲狀腺癌發生早期階段的寶貴工具。

在研究中,Nthy-ori 3-1 已被用於探索甲狀腺疾病(包括自體免疫性甲狀腺炎和甲狀腺腫)背後的分子機制。它可作為與甲狀腺癌細胞系的對照組,特別是在針對氧化壓力與 DNA 損傷作用的研究中。 例如,研究顯示,當 Nthy-ori 3-1 細胞暴露於基因毒性物質時,會誘發 DNA 鏈斷裂及修復反應,這些現象對於理解突變作用及甲狀腺惡性腫瘤的發病機制至關重要。

此外,該細胞系亦被應用於毒理學研究,用以評估環境及藥用化合物對甲狀腺健康的影響。 利用 Nthy-ori 3-1 細胞進行的研究,已闡明細胞對甲狀腺毒性物質及內分泌干擾物所作反應的相關途徑。這使得 Nthy-ori 3-1 成為研究甲狀腺功能調控、疾病建模及治療篩選的重要模型。

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。
