01General information

Description

D341 Med 細胞系由 Friedman 等人於 1988 年,從一名被診斷為髓母細胞瘤的 3 歲男童體內提取的腫瘤組織中建立。髓母細胞瘤是一種高度惡性的兒童腦腫瘤,主要發生於小腦。 由於該細胞系源自一種常見的兒童腦癌,對於研究至關重要,有助於深入了解兒童病例特有的腫瘤生物學與遺傳學。 D341 Med 已被廣泛應用於旨在釐清髓母細胞瘤分子與細胞機制的研究中,包括針對促成腫瘤形成及治療抗藥性的基因突變與訊號傳導路徑之探究。

除了在基礎研究中的作用外,D341 Med 細胞系在評估髓母細胞瘤新治療方法的臨床前研究中也發揮了關鍵作用。其遺傳特徵反映了人類腫瘤中常見的變異,使其成為評估潛在藥物及新型治療策略療效的絕佳模型。 在這些研究中運用 D341 Med 細胞系,有助於彌合實驗室研究與臨床應用之間的鴻溝,並支持開發靶向療法,為罹患這種毀滅性疾病的兒童帶來更佳的治療成效。

05Expression and susceptibility

Protein expression
谷氨酰胺合成酶呈陽性,神經元特異性烯醇化酶呈陽性,膠質纖維酸性蛋白呈陰性,S100(S-100)蛋白呈陰性,神經外胚層抗原呈陽性,可被 UJ13A 單克隆抗體識別

06Handling and culture

Culture medium
EMEM(MEM Eagle),含 2 mM L-谷氨醯胺,含 2.2 g/L NaHCO₃,含 EBSS(Cytion 產品編號 820100a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS 和 1% NEAA
Subculturing
透過移液管上下吸放,輕柔地將燒瓶中的細胞懸浮液均質化,然後取一份具代表性的樣本,以測定每毫升的細胞密度。使用新鮮培養基將懸浮液稀釋至細胞濃度為 1 × 10⁵ 個細胞/毫升,並將調整後的懸浮液分裝至新的燒瓶中,以供進一步培養。
Fluid renewal
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。
