01General information

Description

HNO97 細胞系源自口腔鱗狀細胞癌,此為頭頸部鱗狀細胞癌(HNSCC)的一種亞型。 該細胞系呈現多種染色體異常,包括 3p25-pter、3q、5p、9q22-qter、10p、10q、11cen-p14、 20p 及 20q 等區域的 DNA 拷貝數增加,同時 18q 區域則出現顯著的拷貝數缺失。這些遺傳變異與侵襲性頭頸部鱗狀細胞癌(HNSCC)中常見的變異一致,且與參與腫瘤進展的關鍵致癌基因相關,包括那些涉及細胞週期調控與增殖的基因。

HNO97 細胞系已被廣泛應用於針對腫瘤特異性靶向及胜肽結合的研究。例如,HNO97 細胞系在識別與闡明 HBP-1 胜肽的特性方面發揮了關鍵作用;該胜肽能特異性地結合頭頸部鱗狀細胞癌(HNSCC)細胞,並顯示出用於靶向治療的潛力。 HBP-1 與 HNO97 細胞的結合動力學顯示其能迅速內化,使該細胞系成為研究針對頭頸部鱗狀細胞癌腫瘤內特定分子標靶之新型治療藥物療效的寶貴模型。

此外,HNO97 已被應用於攜帶腫瘤的裸鼠進行生物分佈研究,結果顯示某些肽(如 HBP-1)會優先積聚於 HNO97 腫瘤中,凸顯了其在藥物遞送與影像研究之臨床前模型中的實用性。 該細胞系的遺傳與分子特徵,使其成為研究口腔癌生物學及開發標靶治療的重要工具。

05Handling and culture

Culture medium
DMEM,含 4.5 g/L 葡萄糖、4 mM L-谷氨醯胺、3.7 g/L NaHCO₃ 及 1.0 mM 丙酮酸鈉(Cytion 產品編號 820300a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
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。
