01General information

Description

SCC-4 是一種人類舌部鱗狀細胞癌(SCC)細胞系,廣泛應用於癌症研究中,用以探討口腔癌的進展機制、細胞凋亡以及對化療藥物的反應。口腔鱗狀細胞癌是口腔中常見的惡性腫瘤,通常與吸菸和飲酒等生活方式因素有關。 SCC-4 細胞以其侵襲性強為特徵,常被用於體外模擬腫瘤行為及治療抗藥性。

利用 SCC-4 進行的研究顯示,若干化合物(例如大黃素、大黃酚和大黃酮)可透過內在(線粒體依賴性)和外在(死亡受體介導)兩條途徑誘導細胞凋亡。 大黃素透過內質網壓力、活性氧(ROS)產生及線粒體功能障礙,誘發 S 期細胞週期停滯與凋亡,進而觸發半胱天冬酶-8、-9 及 -3 的活化。 同樣地,研究顯示大黃素可透過破壞線粒體膜電位並促進細胞色素 c 的釋放,導致 G2/M 期停滯並誘導凋亡。 小檗鹼亦可透過增強活性氧(ROS)的產生、增加細胞內 Ca2+ 濃度以及降低線粒體膜電位,從而激活半胱天冬酶-9 和半胱天冬酶-3 途徑,在 SCC-4 細胞中誘導凋亡。

這些發現表明,SCC-4 是一種有效的模型,可用於研究細胞對潛在抗癌藥物所引發的凋亡分子機制,並為針對口腔鱗狀細胞癌的治療策略提供新見解。

Mutational profile
突變:TP53,p.Pro151Ser (c.451C>T)

06Handling and culture

Culture medium
DMEM:Ham's F12(1:1),重量比:3.1 g/L 葡萄糖,重量比:2.5 mM L-谷氨酰胺,重量比:15 mM HEPES, w: 0.5 mM 丙酮酸鈉,w: 1.2 g/L NaHCO₃(Cytion 產品編號 820400a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS 及 400 ng/mL 氫化可的松
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。
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。
