01General information

Description

SNU-1 細胞系源自一名成年人類的胃癌組織,廣泛應用於胃癌研究。該細胞系為研究胃腺癌(一種常見且常具致命性的胃癌類型)背後的分子與細胞機制,提供了重要的研究模型。 SNU-1 細胞對於探究胃癌病理機制中的基因變異與訊號傳導路徑,以及開發和測試新的治療策略,具有特別重要的價值。

SNU-1 細胞呈現上皮形態,其特徵在於表達胃上皮細胞和腺癌的典型標記物,例如癌胚抗原(CEA)和細胞角蛋白。 該細胞系常被用於探索致癌基因、抑癌基因及其他分子因子在胃癌進展中所扮演的角色。研究人員利用 SNU-1 細胞評估化療藥物、標靶治療及聯合治療的療效與作用機制。 此外,SNU-1 細胞亦作為理解腫瘤微環境以及癌細胞與基質細胞之間相互作用的模型。SNU-1 細胞系在胃癌研究中的相關性,凸顯了其在深化我們對這種惡性腫瘤的認識,以及為胃癌患者開發有效治療方法方面的關鍵重要性。

06Handling and culture

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 經熱滅活的胎牛血清
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。
Seeding density
0,3-1 × 10⁶ 細胞/毫升
Fluid renewal
每週 2 至 3 次
Post-thaw recovery
解凍後,將細胞以 5 × 10⁴ 個細胞/cm² 的密度接種於培養皿中,並讓細胞從冷凍過程中恢復,並附著至少 24 小時。
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。
