01General information

Description

SNU-C1 細胞系是從一名韓國成年患者的腹水建立的人類結直腸癌模型。該細胞系源自結腸的中度分化腺癌,屬於源自結直腸癌患者的 SNU 系列細胞系之一。 由於其分子特徵以及在體外條件下相對穩定的生長特性,SNU-C1 已被廣泛應用於眾多針對胃腸道癌症生物學及藥物基因組學的研究中。

在基因組層面上,SNU-C1 的特徵為微衛星不穩定性(MSI),這是一種因 DNA 錯配修復(MMR)系統缺陷而常見於部分結直腸癌的表型。此 MSI 狀態對藥物敏感性及基因組不穩定性具有重要影響。 儘管攜帶多種結直腸癌常見的遺傳變異——包括 WNT 和 p53 等關鍵路徑的突變——SNU-C1 仍展現出獨特的蛋白質組學與轉錄組學特徵,使其適合用於分子亞型分類及高通量藥物反應分析。 該細胞系已被納入「癌症細胞系百科全書」(CCLE)等大規模資料集,其中蛋白質組學定量分析證實其表達模式與上皮起源及 MSI 表型相符。這些特徵使 SNU-C1 成為研究 MSI-高型大腸直腸癌治療反應,以及理解大腸直腸腫瘤內分子多樣性的寶貴資源。

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。
