01General information

Description

HCC-LM3 細胞系是研究肝細胞癌(HCC)的成熟模型,這主要歸因於其極高的轉移潛能。該細胞系在揭示與腫瘤增殖、遷移及治療抗藥性相關的機制方面發揮了關鍵作用。 針對 HCC-LM3 細胞的研究顯示,該細胞系在探索藥物反應以及影響癌症侵襲性的分子路徑方面具有重要作用。例如,研究證實環狀 RNA circMRPS35 在 HCC-LM3 中發揮致癌作用,能促進細胞增殖、遷移、侵襲以及化療抗藥性,特別是對順鉑的抗藥性。 從作用機制來看,circMRPS35 透過吸附微RNA-148a-3p 發揮功能,進而導致 Syntaxin 3(STX3)上調,而 STX3 則透過泛素化與降解來調控磷酸酶與텐신同源蛋白(PTEN)的穩定性。

此外,研究已發現 HCC-LM3 細胞中存在顯著的代謝變化,且這些變化與腫瘤生長及存活率相關。該細胞系與其他肝細胞癌(HCC)模型一樣,在葡萄糖和脂質代謝方面呈現顯著改變,這些改變不僅支持腫瘤的快速增殖,更被視為肝癌的標誌性特徵。 運用單細胞 RNA 定序技術的研究,闡明了肝細胞亞群內的代謝異質性如何影響預後與治療成效。值得注意的是,針對 HCC-LM3 進行的代謝路徑分析,對於識別潛在生物標記物及治療靶點以改善臨床策略至關重要。

06Handling and culture

Culture medium
DMEM,含 4.5 g/L 葡萄糖、4 mM L-谷氨醯胺、3.7 g/L NaHCO₃ 及 1.0 mM 丙酮酸鈉(Cytion 產品編號 820300a)
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。
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。
