01General information

Description

SCaBER 細胞系源自人類膀胱鱗狀細胞癌。該細胞系取自一名 58 歲男性患者,保留了原發腫瘤的許多特徵,包括其鱗狀分化特性。 SCaBER 細胞呈現鮮明的上皮形態,具有顯著的細胞間連接結構,例如橋粒和交指狀微絨毛。這些特徵使其成為研究膀胱鱗狀細胞癌病理與進展的絕佳模型。

SCaBER 細胞呈現低四倍體核型,其染色體數目變異性極高,且具有特徵性的標記染色體。其男性核型同時包含 X 染色體與 Y 染色體,這一點進一步使其有別於其他細胞系。 超微結構研究顯示,該細胞含有豐富的張力絲、脂質體,以及發達的細胞器,例如高爾基體和粗面內質網。這些特性在多次傳代過程中得以維持,確保長期研究的一致性。

此細胞系已被應用於免疫學研究,用以探索腫瘤特異性抗原及其在膀胱癌進展中的作用。 SCaBER 的鱗狀分化特性是研究鱗狀細胞癌中腫瘤相關抗原的關鍵因素,有助於深入了解潛在的診斷標記物及治療靶點。其特徵鮮明的分子與表型特性,使其成為泌尿系統癌症研究中的關鍵資源。

05Handling and culture

Culture medium
EMEM(MEM Eagle),含 2 mM L-谷氨醯胺,含 2.2 g/L NaHCO₃,含 EBSS(Cytion 產品編號 820100a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS 和 1% NEAA
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。
