01General information

Description

SNU-423 細胞系是從一名韓國成年患者建立的人類肝細胞癌(HCC)模型。它是八種源自原發性肝腫瘤的 HCC 細胞系之一,其形態學、遺傳學及病毒學特性均已得到闡明。 SNU-423 具有基質黏附性,並保留了原發腫瘤的許多組織學特徵,與源自肝細胞的上皮形態一致。該細胞系呈現非整倍體現象,且其模態染色體數顯示出染色體不穩定性,此現象在源自肝細胞癌的細胞系中相當常見。

在分子層面上,SNU-423 的顯著特徵在於其基因組內整合了 B 型肝炎病毒(HBV)DNA,此特徵為該系列中所有細胞系所共有的,反映出 HBV 相關肝癌在東亞地區的高盛行率。 雖然該系列中的部分細胞系會表達 HBVx 等 HBV 轉錄本,但尚未有文獻報告 SNU-423 表達的具體轉錄本。此外,SNU-423 無論在 RNA 或蛋白質層面均不表達甲胎蛋白(AFP),這使其與不分泌 AFP 的部分 HCC 亞型相符。 該細胞系已被應用於藥物基因組學篩選研究,例如 LIMORE(肝癌模型資料庫),藉此有助於理解肝癌中的基因-藥物關聯性,包括可能與 HBV 狀態或特定致癌突變相關的藥物反應變異性。

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。
