01General information

Description

BEAS-2B 是一種源自非癌症患者支氣管上皮的不朽化細胞系。 該細胞系是透過將人類支氣管上皮細胞轉化為腺病毒 12-SV40 雜交病毒而建立,此病毒使細胞壽命延長,同時仍保留了原發性支氣管上皮細胞的許多典型形態學及功能特徵。 由於 BEAS-2B 細胞源自氣道上皮,因此廣泛應用於呼吸系統疾病研究,特別是在與可吸入物質的毒理學和藥理學效應相關的研究中。

該細胞系在培養時呈現鵝卵石狀形態,並保留了某些關鍵特徵,例如代謝異體化合物的能力,使其在藥物代謝與呼吸道毒理學研究中極具參考價值。此外,該細胞系亦廣泛應用於探索氣喘、慢性阻塞性肺病(COPD)及癌症的細胞機制研究。 BEAS-2B 細胞會對細胞因子、氧化壓力以及呼吸道暴露於環境因子時常見的其他刺激產生可預測的反應。這使其成為研究肺部細胞發炎與氧化壓力機制的重要模型。

作為生物醫學研究的工具,BEAS-2B 細胞亦常被用於評估空氣中顆粒物的致癌潛力,在此領域中,它們作為模型,有助於理解氣道上皮細胞在接觸致癌物後的變化。 其遺傳特性及易於進行基因操作的特性,進一步增強了其在分子生物學實驗中的實用性,這些實驗旨在釐清與肺部疾病及癌症發展相關的基因表達與訊號傳導路徑。

06Handling and culture

Culture medium
氣道上皮細胞基礎培養基(PromoCell GmbH)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入「生長培養基補充混合物」(PromoCell GmbH)
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培養瓶使用3-5毫升PBS,T75培養瓶則使用5-10毫升。 接著,用 Accutase 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,使其脫附。 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。
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。
