01General information

Description

MNNG/HOS Cl #5 細胞系 [R-1059-D] 是透過以 0.01 微克/毫升濃度的 N-甲基-N'-硝基-N-亞硝基胍 (MNNG)進行體外轉化而衍生,其濃度為 0.01 微克/毫升。 該化合物是一種強效致癌物,且轉化後產生顯著的致瘤性,其證據在於:當以 10⁷ 個細胞進行皮下接種時,裸鼠在 21 天內以 100% 的發生率形成腫瘤。經觀察,這些腫瘤為分化不良的肉瘤或骨肉瘤。 該細胞株最初是從一名 13 歲的白人女性骨肉瘤患者體內建立的,並具有黏附生長特性。

在功能方面,MNNG/HOS Cl #5 細胞在軟瓊脂中展現出高飽和密度和高接種效率,反映出其增強的錨定獨立生長能力,這是惡性轉變的標誌。 此外,這些細胞展現出顯著的纖溶活性,這與增高的致瘤潛力有關。與未經處理的 HOS 細胞相比,經 MNNG 處理的細胞展現出更強的細胞聚集特性,且在軟瓊脂中形成集落的傾向更高,這與其形成腫瘤的能力相關。 在實驗中,MNNG 轉化細胞在裸鼠和倉鼠體內均產生了腫瘤,且細胞與親本 HOS 細胞系相似;而在類似條件下,未經處理的細胞則不具致瘤性。

由於該細胞系提供了化學誘導轉化的模型,因此對於研究癌症進展與腫瘤生物學(尤其是骨肉瘤)亦具實用價值。 這些細胞能在免疫缺陷環境(例如裸鼠)中生長,使其成為臨床前癌症研究的寶貴工具,有助於探究致瘤機制,並可進行治療干預措施的潛在測試。

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
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
1 × 10⁴ 個細胞/cm²
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。
