01General information

Description

HCC1395 細胞系是一種源自人類基底樣乳癌的模型,該亞型常與三陰性乳癌(TNBC)相關。此細胞系以其高度的遺傳複雜性著稱,包括顯著的基因組不穩定性,以及具侵襲性乳癌典型特徵的顯著突變譜。 針對 HCC1395 的研究已鑑定出大量體細胞突變與拷貝數變異,這使其被歸類為三陰性乳癌(TNBC)研究的代表性模型。

HCC1395 對於探索基底樣乳癌中藥物抗藥性與轉移的潛在機制尤具參考價值。一項研究特別強調利用此細胞系評估沉默與細胞遷移相關基因(如 ZEB2)的影響,結果顯示其下調可降低 HCC1395 的侵襲潛能。 此外,該細胞系的突變圖譜常包含與 DNA 損傷反應及細胞週期調控相關基因的變異,例如 TP53——此基因在基底樣乳癌中經常發生突變。

這些特徵使 HCC1395 成為探索新治療策略(包括旨在克服抗藥性的標靶治療與聯合治療)之臨床前研究的重要工具。透過整合高通量定序與功能基因組學方法,研究人員利用 HCC1395 更深入地理解三陰性乳癌(TNBC)的病理生理機制,從而促進更有效治療方案的開發。

06Handling and culture

Culture medium
RPMI 1640,含:4.5 g/L 葡萄糖、2 mM L-谷氨醯胺、10 mM HEPES、1 mM 丙酮酸鈉、1.5 g/L NaHCO₃(820702a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Dissociation reagent
Accutase
Subculturing
從貼壁細胞中移除舊培養基,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶需使用3-5毫升PBS,T75培養瓶則需使用5-10毫升。 接著,用 TrypLE Express 完全覆蓋細胞,T25 培養瓶使用 1–2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8–10 分鐘,使其脫落。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。
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。
