01General information

Description

Kera-308 細胞系是由成年小鼠皮膚角質細胞建立而來,為研究皮膚生理學的複雜過程——尤其是傷口癒合與角質細胞功能——提供了一個多功能的模型。 該細胞系在特定條件下(例如經白桑根萃取物處理)展現出顯著的角蛋白上調能力,包括由傷口誘導產生的角蛋白類型,例如 Krt6a。 Kera-308 細胞對 12-肉豆蔻酸酯 13-乙酸酯(PMA)的反應性,凸顯了其在探究皮膚修復與再生背後細胞機制方面的實用性。

Kera-308 細胞的一大突出特徵是其劑量依賴性的增殖反應,此反應可透過白桑根萃取物等外部刺激顯著增強。此特性使 Kera-308 成為探究角質細胞在治療藥物作用下增殖與分化之分子基礎的絕佳工具。

此外,Kera-308 細胞在傷口癒合情境下的轉錄譜,尤其是其上調的角蛋白絲及 CXCL12/CXCR4 訊號傳導,為皮膚修復過程中所涉及的細胞與分子動態提供了極具價值的見解。 這些訊號傳導路徑的參與,凸顯了 Kera-308 細胞在探索增強傷口癒合及治療皮膚疾病之新治療策略方面的相關性。

05Handling 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
TrypLE Express(Life Technologies)
Subculturing
移除培養基,並使用不含鈣和鎂的PBS沖洗附著細胞(T25細胞培養瓶需3-5毫升PBS,T75細胞培養瓶需5-10毫升)。 加入 Tryple Express(T25 培養瓶每瓶 1–2 毫升,T75 培養瓶每瓶 2.5 毫升),務必完全覆蓋細胞片。於 37 度下孵育 15 分鐘。 小心用 10 毫升培養基將細胞重新懸浮(必要時可使用細胞刮刀),以 300xg 離心 5 分鐘,將細胞重新懸浮於新鮮培養基中,並分裝至裝有新鮮培養基的新培養瓶中。
Seeding density
1 × 10⁴ 個細胞/cm²
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.

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。
