01General information

Description

CERV-186 細胞系源自子宮頸癌 MRI-H-186 的異種移植,並於體外建立,用作侵襲性、大細胞型、非角化鱗狀細胞癌的生物模型。 該細胞系由梅森研究所(Mason Research Institute)的博德根博士(Dr. Bodgen)指導下建立,並經調整以適應體內移植。根據其基因組特性,MRI-H186 含有約 26 份整合的 HPV16 基因組(包含全長及截短形式),這顯著影響了其轉錄組特徵。

MRI-H186 細胞的獨特之處在於其強勁表達 HPV16 早期轉錄本(包含全長及截短形式),其中尤以高水平的 E5 全長 (fl) RNA 為著。此轉錄特徵與 CaSki 及 MRI-H196 等其他子宮頸癌細胞系所觀察到的現象明顯不同。 此外,就其他各種轉錄本的表達而言,MRI-H186 的轉錄活性與 HPK-IA 和 C3 細胞系所觀察到的模式高度一致,表明這些模型在轉錄行為上具有相似性。 MRI-H186 細胞中同時存在 HPV16 基因組的全長與截短型整合,是其強烈表達早期病毒轉錄本的關鍵因素,這一點尤其體現在 E5 全長 (fl) RNA 的顯著表達上。 這種強烈的轉錄活性在早期多聚腺苷酸化訊號處達到高峰,凸顯了 MRI-H186 細胞系內獨特的轉錄動態。

06Handling and culture

Culture medium
DMEM:Ham's F12(1:1),重量比:3.1 g/L 葡萄糖,重量比:2.5 mM L-谷氨酰胺,重量比:15 mM HEPES, w: 0.5 mM 丙酮酸鈉,w: 1.2 g/L NaHCO₃(Cytion 產品編號 820400a)
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。
Seeding density
2 × 10⁴ 個細胞/cm² 將在 7 天內形成密合的單層細胞
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.

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。
