01General information

Description

RenCa-IL2 是 RenCa 細胞系(一種小鼠腎腺癌細胞系)的基因改造變體。此項特定改造涉及將編碼白細胞介素-2(IL-2)的基因穩定轉染至該細胞系中;IL-2 是一種在調節白血球方面至關重要的細胞因子,而白血球對免疫系統而言至關重要。 將 IL-2 基因導入 RenCa 細胞,旨在於受控的實驗環境中,研究 IL-2 表達對腫瘤生長、免疫細胞募集以及免疫治療策略療效的影響。

RenCa 細胞最初源自 Balb/c 小鼠的腎癌,現被用於探索癌症免疫學及治療方法,特別是為了了解腫瘤如何逃避免疫系統的攻擊,以及如何對抗這些防禦機制。 將 IL-2 導入 RenCa 細胞,有助於研究此細胞因子在調控腫瘤微環境中的作用,並可能增強 T 細胞和自然殺手(NK)細胞在腫瘤部位的募集與活化。這對於開發更有效的癌症免疫療法而言,具有特別重要的意義。

利用 RenCa-IL2 細胞系進行的研究,可為 IL-2 促進抗腫瘤免疫反應的機制提供寶貴見解,從而作為評估利用細胞因子刺激免疫反應之新型癌症治療方法的模型。 此外,RenCa-IL2 細胞系對於評估腫瘤微環境中免疫細胞相互作用的動態變化十分有用,為生物學相關性及治療潛力的臨床前測試提供了寶貴的工具。

06Handling and culture

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。

每週 2 至 3 次
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。
