01General information

Description

SNU-16 細胞系源自一名成年人類的低分化胃癌。該細胞系廣泛應用於胃癌研究,為探究胃腺癌發生與進展所涉及的分子及細胞機制提供了研究模型。 SNU-16 細胞對於探究與這種侵襲性胃癌相關的基因變異、訊號傳導路徑及腫瘤微環境而言,具有特別重要的價值。

SNU-16 細胞呈現上皮細胞形態,其特徵在於表達胃癌標記物,包括癌胚抗原(CEA)及各種細胞角蛋白。 已知該細胞線具有 c-MET 基因擴增及 MET 受體過度表達的特徵,而 MET 受體在細胞生長、存活及轉移過程中扮演重要角色。研究人員利用 SNU-16 細胞探索 MET 訊號傳導路徑在胃癌中的作用,並評估 MET 抑制劑及其他標靶治療的療效。 此外,SNU-16 細胞亦被應用於藥物抗性研究、高通量篩選試驗,以及新型化療藥物的臨床前測試。SNU-16 細胞系在胃癌研究中的相關性,凸顯了其在深化我們對該疾病的理解,以及為胃癌患者開發更有效治療策略方面的關鍵重要性。

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。
