01General information

Description

IM95m 細胞系源自中度分化的胃腺癌,其顯著特徵在於能產生大量細胞因子,尤其是肝細胞生長因子(HGF)、血管內皮生長因子(VEGF)及白細胞介素-8(IL-8)。 此特性使 IM95m 成為探索腫瘤與血管生成相互作用,以及癌症增殖與轉移機制的重要模型。該細胞系呈現上皮狀形態,具有緊密的細胞間連接,其計算出的倍增時間約為 25 小時。 IM95m 最初是從胃癌檢體中建立的,並已顯示出在體內形成腫瘤的能力,表明其具有致瘤潛力。

IM95m 能分泌高濃度的 HGF 和 VEGF,這對於癌症進展的研究尤為重要,因為這些生長因子是血管生成和腫瘤生長的關鍵驅動因子。HGF 的分泌持續且顯著,這增強了 IM95m 在闡明 HGF 驅動的癌症通路行為方面的潛力。 這些因子的分泌顯示,IM95m 在研究針對性療法(例如 VEGFR 抑制劑)的抗藥性機制方面具有重要作用,因為 HGF 介導的訊號傳導可能在降低治療療效的過程中扮演一定角色。

除了產生與血管生成相關的細胞因子外,IM95m 亦已針對涉及腫瘤生長抑制的實驗模型進行了反應評估。其表達模式支持針對 VEGF 與 HGF 途徑同時進行治療策略的研究,此種方法有望提供更全面的癌症治療成果。

05Handling 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培養瓶需使用3-5毫升PBS,T75培養瓶則需使用5-10毫升。 接著,用 TrypLE Express 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,使其脫落。 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.

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。
