01General information

Description

HCC1569 是一種源自原發性導管癌的人類乳癌細胞系。該細胞系呈現基底樣表型,其特徵為雌激素受體(ER)陰性且 HER2 陽性,屬於一種具有明確臨床及治療意義的分子亞型。 與其他基底樣型乳癌相似,HCC1569 缺乏雌激素受體(ER)和黃體素受體(PR)的表達,但呈現 ERBB2(HER2)致癌基因的擴增與過度表達,而該基因是 HER2 靶向治療的關鍵標靶。 該細胞系呈現高度非整倍體現象,並攜帶多項與乳癌生物學相關的基因組變異。

HCC1569 被納入大規模基因組分析計畫,例如「癌症細胞系百科全書」(CCLE)以及整合突變、拷貝數、甲基化和表達數據的相關研究。這些數據集顯示,HCC1569 攜帶與侵襲性乳腺腫瘤(包括涉及 HER2 的腫瘤)相符的結構變異和拷貝數擴增。 功能性基因組篩選已凸顯出該細胞系對 HER2 訊號傳導路徑的依賴性,這支持其用於評估 HER2 靶向療法及抗藥性機制。

此外,HCC1569 的 HLA 基因型與表達譜已獲闡明,這對免疫療法的開發具有重要意義。 該細胞系已被收錄於 HLA 分型與新抗原預測資料庫中,為探索 HER2 陽性乳癌背景下的 T 細胞表位呈遞與免疫識別提供了契機。這項免疫基因組註釋使 HCC1569 不僅成為研究致癌訊號傳導的寶貴資源,亦能用於評估腫瘤與免疫系統的相互作用,並設計個人化免疫療法。

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。
