01General information

Description

OVCAR-8 是一種從一名晚期卵巢腺癌患者體內建立的人類卵巢癌細胞系。該細胞系最顯著的特徵在於其對順鉑和卡鉑具有顯著的抗藥性,而這兩種藥物在該患者的治療過程中曾以高劑量使用。 OVCAR-8 廣泛應用於研究卵巢癌化療抗藥性的機制,以及開發克服鉑類化療抗藥性的策略。

OVCAR-8 細胞呈現上皮細胞形態,並在培養中以黏附方式生長。該細胞系的特徵在於具有與高分化度卵巢癌相關的分子及表型特徵,包括 DNA 損傷修復機制之改變,以及其他有助於腫瘤在化療壓力下存活的途徑。 與某些其他卵巢癌細胞系不同,OVCAR-8 未檢測到金屬硫蛋白的表達,該蛋白質被認為在對重金屬類藥物的耐藥性中發揮作用。 然而,該細胞系對鎘及其他藥物展現交叉耐藥性,暗示可能涉及其他耐藥機制,例如谷胱甘肽水平升高及DNA修復能力增強。

OVCAR-8 是臨床前研究中篩選化療藥物、評估標靶治療以及研究化療抗藥性生物學機制的寶貴工具。 研究人員利用此細胞系,探索旨在使耐藥腫瘤對標準治療產生敏感性的藥物組合。此外,OVCAR-8 還有助於深入了解卵巢癌細胞的遺傳與分子適應機制,這些機制正是其即使在接受強力化療方案下仍能存活與持續存在的基礎。其臨床相關性與耐藥特徵,使其成為推動卵巢癌研究與治療開發的重要資源。

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。
