01General information

Description

WSU-HN6 是一種源自上呼吸消化道腫瘤(具體而言是舌根部)的人類鱗狀細胞癌(SCC)細胞系。 該細胞系屬於一套全面的頭頸部鱗狀細胞癌(HNSCC)細胞系組合,旨在模擬此類癌症的生物學特性。WSU-HN6 在闡明 HNSCC 中常見的分子改變方面發揮了關鍵作用,特別是那些涉及細胞週期調控與生長訊號傳導路徑的改變。

該細胞系表現出週期蛋白依賴性激酶(CDKs)活性升高,尤其是 CDK4 和 CDK6,這與腫瘤抑制基因 p16INK4A 的失活相一致。 雖然許多頭頸部鱗狀細胞癌細胞系會過度表達週期蛋白 D1,但 WSU-HN6 並未出現此現象,這暗示了 CDK 活化的其他途徑,例如激酶過度表達或負調節因子缺失。 此外,WSU-HN6 雖表達野生型 p53,卻呈現細胞週期調控失調,暗示存在其他分子缺陷,包括 p21 功能或調控方面的潛在缺陷。

在功能方面,WSU-HN6 顯示出酪胺酸磷酸化水平升高,反映出促進生長的受體酪胺酸激酶出現異常活化。已有文獻記載此細胞系中表皮生長因子受體(EGFR)活性增強,儘管與同組其他細胞系相比,其 EGFR 蛋白過度表達程度尚屬溫和。 WSU-HN6 中的 EGFR 仍能對配體刺激產生反應,且功能完好。這些特徵使 WSU-HN6 成為研究頭頸部癌症中生長訊號失調及 CDK 路徑異常的寶貴體外模型。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
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。
