01General information

Description

VK2/E6E7 細胞系是一種人類陰道上皮細胞系,是利用人類乳突病毒(HPV)第 16 型 的 E6 和 E7 致癌基因進行永生化處理而獲得的。 此種永生化方法在延長細胞複製壽命的同時,亦保留了正常陰道上皮細胞的許多功能與形態特徵。VK2/E6E7 細胞屬於 HPV16/E6E7 永生化細胞系系列的一部分,該系列還包含外陰頸 (Ect1/E6E7)及子宮頸內上皮(End1/E6E7)上皮細胞,為研究女性下生殖道生物學提供了全面的體外模型。

VK2/E6E7 細胞呈現類角質細胞的形態,在培養中形成鬆散的集落,有別於外子宮頸細胞較為分層的外觀。它們表達多種上皮分化標記物,包括細胞角蛋白 CK8、CK18、CK19 以及 involucrin。 值得注意的是,該細胞亦表達與多層鱗狀上皮基底層以上分化相關的標記物 CK10 和 CK13,這表明其保留了正常陰道上皮細胞的關鍵特徵。 此外,VK2/E6E7 細胞會微弱地表達聚合型免疫球蛋白受體的分泌成分(SC),該成分通常在陰道組織中缺失,但在該細胞系中卻呈現上調。 這些特徵使 VK2/E6E7 成為研究陰道上皮功能、宿主與病原體相互作用及黏膜免疫學的寶貴工具,同時也適用於測試供陰道內使用的藥理製劑。

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。
