01General information

Description

SW1271 細胞系是一種源自成人患者的人類小細胞肺癌(SCLC)模型。其特徵為具有 SCLC 典型的神經內分泌表型,並展現出與治療敏感性及抗藥性相關的分子特徵。 在一項針對包括 SW1271 在內的 SCLC 細胞系所進行的全面表觀基因組範圍甲基化分析中,該細胞系展現出特定的 DNA 甲基化模式,且與對數類抗癌藥物的化療敏感性呈相關性。這些藥物包括 Aurora 激酶抑制劑、CDK 抑制劑以及 DNA 損傷劑。 SW1271及其他小細胞肺癌模型中,TREX1、SLFN11、CEP350和KDM1A等關鍵基因的甲基化狀態,已被證實與藥物反應的改變有關,這表明表觀遺傳調控是決定治療療效的關鍵因素。

此外,SW1271 已被用於整合性基因組與表觀基因組研究,以釐清小細胞肺癌中各亞型的特異性脆弱性。 該細胞系連同代表不同小細胞肺癌轉錄亞型(ASCL1、NEUROD1、POU2F3 和 YAP1)的其他細胞系,有助於闡明該疾病內的異質性。 SW1271 的甲基化圖譜有助於我們理解影響基因表達和藥物反應的調控機制,包括腫瘤抑制基因的抑制以及譜系特異性轉錄因子的調控失調。這些見解使 SW1271 成為研究小細胞肺癌中表觀遺傳驅動路徑,以及識別潛在生物標記物和治療靶點的寶貴模型。

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。
