01General information

Description

HCC1428 是一種人類乳癌細胞系,根據全基因表達譜分析,被歸類為管腔 B 型。該細胞系源自原發性乳癌腫瘤,並保留了管腔型乳癌的關鍵特徵,包括雌激素受體(ER)的表達。 在針對乳腺癌細胞系與原發性腫瘤進行的轉錄組比較分析中,HCC1428 始終與管腔 B 亞型腫瘤歸為同一群組;該亞型以較高的增殖指數為特徵,且其基因表達特徵有別於管腔 A 型腫瘤。

在功能方面,相較於其他乳癌亞型,HCC1428 細胞展現出中等程度的增殖與分化能力。該細胞對雌激素有反應,並維持成熟的管腔表型,表達與乳腺分化上皮譜系相關的標記物。 在臨床前研究中,由於 HCC1428 等管腔 B 細胞系在部分程度上依賴雌激素受體(ER)訊號傳導,且相較於管腔 A 亞型具有更高的增殖能力,因此常被用於評估內分泌療法及抗藥性機制。

HCC1428 亦收錄於「癌症細胞系百科全書」(CCLE)中,該資料庫提供基因、轉錄組及藥理學特徵的整合數據集。這些數據顯示,HCC1428 具有雌激素受體陽性、管腔型乳癌典型的基因表達及拷貝數變異。 因此,該細胞系是研究荷爾蒙受體陽性乳癌的寶貴模型,特別是在管腔 B 亞型特有的生物學特性及對標靶治療的反應方面。

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。
