01General information

Description

CLS-ACI-1 細胞系於 1998 年由一例實體乳腺癌建立,該癌症是透過向模式生物口服每公斤體重 20 毫克的 7,12-二甲基苯並[a]蒽(DMBA)所誘導而成。 DMBA 是一種眾所周知的強效致突變劑和致癌物,常被用於實驗腫瘤學中誘導癌症,特別是在與乳癌相關的研究中。 從腫瘤組織建立 CLS-ACI-1 細胞系,有助於對乳癌生物學進行廣泛的體外探索,特別是在理解由 DMBA 等化學物質引發的致癌機制方面。

利用 CLS-ACI-1 細胞系進行的體外研究,為與乳腺癌相關的細胞通路和基因變異提供了關鍵見解。該細胞系是腫瘤學研究的重要工具,應用範圍包括藥物測試、抗藥性機制以及細胞對藥理學製劑的反應。 作為一種連續細胞系,CLS-ACI-1 為研究乳癌的進展與治療提供了穩定且可重複的模型,有助於開發針對人類因化學物質誘發之類似癌瘤的更有效治療策略。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Dissociation reagent
Accutase
Subculturing
將懸浮細胞收集至 15 毫升試管中,並用不含鈣和鎂的 PBS 輕柔地洗滌貼壁細胞(T25 培養瓶使用 3-5 毫升,T75 培養瓶使用 5-10 毫升)。 加入 Accutase(T25 培養瓶使用 1–2 毫升,T75 培養瓶使用 2.5 毫升),確保完全覆蓋細胞層。讓細胞於室溫下孵育 10 分鐘。 孵育完成後,將懸浮細胞與貼壁細胞合併並進行離心。離心後,小心地將細胞沉澱重新懸浮,並將細胞懸液轉移至裝有新鮮培養基的新培養瓶中。
Seeding density
2 × 10⁴ 個細胞/cm² 約需 6 至 7 天即可形成密合的細胞層
Fluid renewal
每 3 至 5 天
Post-thaw recovery
解凍後,將細胞以 5 × 10⁴ 個細胞/cm² 的密度接種於培養皿中,並讓細胞從冷凍過程中恢復,並附著至少 24 小時。
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。
