01General information

Description

ES-2 細胞系源自分化程度較低的卵巢透明細胞癌,為研究此種侵襲性癌症亞型的生物行為及治療反應,提供了一個獨特的體外模型。 ES-2 細胞最初是在軟瓊脂中培養的,這種方法有利於癌細胞生長,同時抑制成纖維細胞的生長;因此,ES-2 細胞提供了一個穩健的系統,可在密切模擬體內環境的三維基質中,分析腫瘤細胞的相互作用及藥物抗性機制。

在藥理學方面,ES-2 細胞對多種化療藥物(包括多柔比星、順鉑、卡莫司汀、依托泊苷和氰基莫羅林多柔比星 (MRA-CN))表現出低至中度的抗藥性。 這種耐藥性特徵使 ES-2 成為腫瘤學研究的重要工具,特別是在開發和測試新的化療方案及聯合療法方面。 此外,ES-2 細胞中 P-糖蛋白的表達量較低,這一點至關重要,因為 P-糖蛋白通常與藥物從癌細胞中外排有關,進而導致多重藥物抗性。因此,研究 ES-2 細胞有助於深入了解如何克服卵巢透明細胞癌的藥物抗性。

06Handling and culture

Culture medium
麥考伊 5a 培養基,含:3.0 g/L 葡萄糖,含:穩定型谷氨酰胺,含:2.0 mM 丙酮酸鈉,含:2.2 g/L NaHCO₃(Cytion 產品編號 820200a)
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。
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.

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。
