01General information

Description

SK-N-DZ 細胞系是從一名神經母細胞瘤患兒的轉移性骨髓中建立的人類神經母細胞瘤模型。 該細胞系屬於 SK-N 系列神經母細胞瘤細胞系之一,並展現出源自神經嵴的腫瘤細胞特徵。這些細胞在培養中呈黏附生長,且含有少量側群(SP)細胞,這表明其存在具有高藥物外排能力的類癌症幹細胞亞群。

SK-N-DZ 細胞已被廣泛應用於研究,以釐清遺傳及表觀遺傳改變在神經母細胞瘤中的作用。研究顯示,該細胞系攜帶 MYCN 基因擴增及 ALK 基因突變,這兩者皆與高風險神經母細胞瘤的侵襲性表型及不良預後有關。 此外,SK-N-DZ 亦被用於評估對維甲酸類及維生素 E 衍生物等藥物的治療反應。研究顯示,SK-N-DZ 對 13-順式維甲酸具有獨特的敏感性,與其他神經母細胞瘤細胞系不同,即使在低濃度下亦會出現顯著的細胞裂解現象。

SK-N-DZ 亦被應用於探索神經母細胞瘤分化與幹細胞特性的實驗中。 該細胞系在特定治療條件下形成神經突延伸的能力,凸顯了其在探究腫瘤分化與細胞可塑性方面的潛力。這些特徵,加上其特徵明確的遺傳背景,使 SK-N-DZ 成為推動治療策略發展及理解神經母細胞瘤分子基礎的寶貴模型。

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。
