01General information

Description

HROG59 是一株源自一名被診斷為世界衛生組織(WHO)第四級膠質母細胞瘤之成人患者,其新鮮切除腫瘤組織所建立的原代人類多形性膠質母細胞瘤(GBM)細胞系。該細胞系的建立,是為了在系統性努力中開發能保留患者特異性生物學及分子特徵的超低傳代次數膠質瘤模型。 HROG59 細胞在體外呈黏附生長,並展現出原發性 GBM 培養典型的成纖維細胞樣形態。該細胞系在標準化的培養條件下維持,以最大限度地減少基因漂移並保持表型穩定性。

HROG59 已被用於評估膠質母細胞瘤治療中對標準治療及試驗性藥物的敏感性,包括烷化劑和靶向抑制劑。 作為低傳代數、源自患者的膠質母細胞瘤模型,HROG59 提供了一個與臨床相關的體外系統,用於研究膠質母細胞瘤的生物學特性、腫瘤間異質性及治療反應機制,同時能高度忠實地再現原始腫瘤標本的特徵。

04Handling 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。
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.

05Quality 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 50% 基礎培養基 + 40% 胎牛血清 (FBS) + 10% 二甲基亞砜 (DMSO),或 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,可提高細胞存活率並減輕冷凍引起的應激。
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。
