01General information

Description

F9 細胞系是一種源自 C57BL/6 小鼠睪丸畸胎瘤的小鼠胚胎癌模型,是發育生物學與胚胎學領域中的一項重要研究工具。 當 F9 細胞暴露於視黃酸和二丁酰基環磷酸腺苷(cAMP)時,便能分化為壁層內胚層。這種分化特徵在於細胞行為和蛋白質表達的顯著變化,包括纖溶酶原活化劑、層粘連蛋白和 IV 型膠原蛋白的合成。 這些蛋白質對於理解早期胚胎階段的組織發育和基質形成過程至關重要。

值得注意的是,cAMP 誘導 F9 細胞分化的有效性取決於是否事先以視黃酸處理,這表明這些訊號分子在觸發發育途徑方面存在複雜的相互作用。 此外,F9 細胞的特徵在於擁有三個 β1 整合素基因拷貝,這可能影響細胞黏附與移動性,進一步凸顯其在研究細胞相互作用與細胞外基質組成方面的實用性。 這些細胞的安全性評估包括對短肢病毒(小鼠天花)的檢測,結果呈陰性,確保其適用於廣泛的實驗應用,且無病毒污染的風險。

06Handling and culture

Culture medium
DMEM,含 4.5 g/L 葡萄糖、4 mM L-谷氨醯胺、3.7 g/L NaHCO₃ 及 1.0 mM 丙酮酸鈉(Cytion 產品編號 820300a)
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。
Seeding density
在細胞培養瓶內塗佈明膠。以 1 × 10⁴ 個細胞/cm² 的密度接種,約 4 天後即可形成密合的細胞層。
Fluid renewal
每週 2 至 3 次
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。
