01General information

Description

SK-CO-1 細胞系是一種源自腹水轉移灶的人類結直腸腺癌模型。該細胞系在癌症研究中被廣泛應用,用於探究結直腸癌(CRC)進展及對治療干預反應背後的分子機制。 SK-CO-1 細胞在培養中呈黏附生長,並展現與上皮性腫瘤細胞相符的形態特徵。該細胞系已被納入大規模基因組研究,例如「癌症細胞系百科全書」(CCLE),該計畫提供了全面的遺傳學、轉錄組學及藥理學特徵分析。

針對 SK-CO-1 的遺傳學研究已鑑定出對 CRC 病理機制至關重要的基因突變與拷貝數變異,包括 TP53、KRAS 及 APC 的基因變異。這些特徵使其成為探索 WNT/β-catenin 訊號傳導等路徑的寶貴模型,該路徑在結直腸腫瘤發展中扮演重要角色。 此外,藥理篩選顯示該細胞系對化療藥物具有不同的敏感性,有助於研究人員識別藥物反應的潛在生物標記物。

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
倒出培養基,並用 0.25% 胰蛋白酶、0.03% EDTA 溶液沖洗。 倒出溶液,並再加入 1 至 2 毫升胰蛋白酶-EDTA 溶液。將燒瓶置於室溫(或 37°C)靜置,直至細胞脫落。加入新鮮培養基,吸出舊培養液後,將細胞分裝至新的培養燒瓶中。
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.

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。
