01General information

Description

MET-5A 細胞系源自成人胸膜的間皮細胞,常被用於與間皮瘤相關的研究;間皮瘤是一種影響肺部、腹部及心臟間皮內襯的癌症。 這些細胞對於研究間皮瘤的生物學特性、病理機制及治療方法至關重要,特別是在釐清環境因素(例如石棉暴露)如何導致此種癌症發生的過程中。MET-5A 細胞亦被用於探索細胞轉化、腫瘤進展以及細胞對各種化療藥物的反應機制。

MET-5A 細胞呈現典型的上皮形態,並保留正常間皮細胞的特徵,包括表達細胞角蛋白和維曼汀等間皮標記物。這些細胞對炎症刺激有反應,可用於研究間皮瘤病理機制中的炎症過程。 研究人員利用 MET-5A 細胞來探究與間皮瘤相關的遺傳及分子變化,並測試潛在治療化合物的療效與毒性。 MET-5A 細胞在建模間皮細胞生物學方面的相關性,以及其在間皮瘤研究中的作用,使其成為深化我們對這種侵襲性癌症的理解與治療不可或缺的工具。

06Handling and culture

Culture medium
培養基 199,濃度:1.5 克/公升 NaHCO₃
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements

在培養基中加入 15% FBS、15 mM HEPES 及 1% ITS+

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。
