01General information

Description

VMRC-RCZ 細胞系是一種源自透明細胞型腎癌患者的人類腎細胞癌(RCC)細胞系。該細胞系的建立旨在探究腎癌發生的生物學與遺傳學基礎,特別是針對染色體異常與腫瘤進展方面的研究。 對 VMRC-RCZ 進行的細胞遺傳學分析顯示,其第 9 號染色體短臂(9p21-22 區域)發生缺失。此缺失導致關鍵腫瘤抑制基因(如 CDKN2A)的喪失;該基因常與多種惡性腫瘤相關,並在細胞週期調控中發揮作用。

在更廣泛的癌症基因組分析中,VMRC-RCZ 有助於繪製多種腫瘤類型的純合性缺失圖譜。這些研究顯示,包括 VMRC-RCZ 在內的癌症細胞系中,9p21 等區域常呈現結構不穩定性,這表明該區域的基因組缺失可能在腫瘤演化過程中賦予選擇性生長優勢。 此外,VMRC-RCZ 已被納入高解析度基因組分析平台,用於系統性地識別與癌症相關的突變及拷貝數變異,使其成為研究腎細胞癌(RCC)病理機制,以及探索腎臟惡性腫瘤潛在治療弱點的寶貴模型。

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。
