01General information

Description

NCI-H1793 是一種源自一名患有肺腺癌成人患者的人類非小細胞肺癌(NSCLC)細胞系。 該細胞呈現上皮細胞形態,並在標準組織培養條件下以黏著方式生長。作為肺腺癌的代表性模型,NCI-H1793 保留了與此組織學亞型相關的關鍵分子及表型特徵,因此適合用於肺癌生物學、腫瘤進展及治療反應的體外研究。

對 NCI-H1793 的分子特徵分析已鑑定出 KRAS 致癌基因中的一種活化突變(G12C),這是肺腺癌中常見的驅動突變。 此突變會導致下游訊號傳導路徑(包括 MAPK 和 PI3K-AKT 級聯反應)持續活化,從而促進細胞增殖與存活。 KRAS G12C 的存在使 NCI-H1793 對於研究 RAS 驅動的致癌訊號傳導,以及評估針對突變型 KRAS 或其下游效應因子的標靶抑制劑,具有特別重要的價值。 據報導,該細胞系還攜帶其他非小細胞肺癌(NSCLC)典型的基因組突變,這進一步證實了其作為分子定義肺癌前臨床模型的相關性。

由於其明確的致癌背景和上皮性腫瘤表型,NCI-H1793 廣泛應用於評估 KRAS 突變型肺癌的標靶療法、抗藥性機制及聯合治療策略的研究中。 它為功能基因組學、藥物篩選及路徑分析提供了一個穩健的平台,旨在闡明 RAS 驅動的惡性腫瘤中的脆弱點。

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。
