01General information

Description

水牛鼠肝(BRL)細胞系是從水牛鼠肝組織中自發性永生化的細胞系,由於其保留了類似胚胎幹細胞(ES)的多能性及正常的核型,因此具有重要價值。 BRL 細胞會產生一種在幹細胞生物學中具有獨特應用價值的條件培養基(BRL-CM);它能抑制已建立的胚胎癌(EC)和胚胎幹(ES)細胞系的分化。 此特性使得這些幹細胞得以在無需養分細胞的情況下維持於未分化狀態,儘管這種支持僅在有限期間內可行,這凸顯了 BRL-CM 在長期幹細胞培養中的應用限制。

此外,BRL 細胞系還提供了一個有趣的模型,用於研究基因改造對細胞行為的影響,這可從正常 BRL 細胞與 Ha-ras-1 轉化 BRL 細胞對細胞骨架抑制劑的不同反應中得到說明。 Ha-ras-1 致癌基因的轉化不僅改變了細胞反應,還增強了微絲和微管的穩定性,進而改變了細胞的結構完整性。 這些發現強調了細胞骨架在維持細胞形狀和多能性方面的潛在作用,這對於正常生理狀態以及涉及細胞轉化與分化的疾病狀態而言,都至關重要。

05Handling and culture

Culture medium
EMEM(MEM Eagle),含 2 mM L-谷氨醯胺,含 2.2 g/L NaHCO₃,含 EBSS(Cytion 產品編號 820100a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS 和 1% NEAA
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。
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.

06Quality 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。
