01General information

Description

SNU-216 細胞系是一種源自中度分化腺癌患者轉移性淋巴結的人類胃癌模型。該細胞系屬於一系列胃癌模型之一,這些模型旨在研究胃癌的生物學特性,特別是針對腫瘤抗原表達、基因突變及治療反應等面向。 SNU-216 細胞在培養中呈現黏附性生長模式,形成異質性彌散單層,細胞形態呈圓形至橢圓形,且核質比較低。

基因分析顯示,SNU-216 細胞系存在顯著的突變,包括 TP53 基因的變異。具體而言,已鑑定出第 6 外顯子中的突變,此突變很可能影響其腫瘤抑制功能。 此外,腫瘤抗原研究顯示,SNU-216 細胞高表達癌胚抗原 (CEA) 和組織多肽抗原 (TPA),且未檢測到甲胎蛋白 (AFP)。 這些特徵使該細胞系成為研究胃癌分子與遺傳特徵,以及探索與腫瘤標記物相關診斷與治療應用的寶貴工具。

SNU-216 亦已被收錄於《癌症細胞系百科全書》(CCLE)中,提供了廣泛的基因組、轉錄組及藥理學數據。 該細胞系的分子特徵已被用於預測對標靶治療的敏感性,並研究涉及受體酪胺酸激酶和 PI3K 訊號傳導等途徑。其被納入此資源,凸顯了其作為胃癌研究與藥物開發之臨床前模型的重要性。

移除培養基,加入新鮮的 0.25% 胰蛋白酶與 0.02% EDTA 溶液,將培養瓶置於 37''''C 靜置 3 至 5 分鐘,加入培養基並收集細胞,將培養基轉移至 15 毫升試管中,離心後吸除培養基,用培養基重新懸浮細胞沉澱,並分裝回培養瓶中
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。
