01General information

Description

CCRF-CEM 細胞是一種常用於免疫腫瘤學及免疫學研究的人類 T 淋巴母細胞。這些細胞是從一名患有急性淋巴細胞白血病(ALL)的 4 歲白人女童的外周血中分離出來的。

CCRF-CEM 為懸浮生長細胞,在離心瓶中培養時可達到高細胞密度。CCRF-CEM 細胞的核型分析顯示,其模態染色體數為 47 條,範圍介於 41 至 95 條之間。這些細胞未顯示特定染色體的一致性缺失或增益,亦無標記染色體。 然而,在45條染色體的細胞中,有28%呈現C染色體缺失;在所有細胞中,有53%多出一條D染色體,另有35%多出一條F染色體。

CCRF-CEM 細胞具有致瘤性,可在敘利亞倉鼠體內引發腫瘤。這些細胞表達 CD3、CD5、CD7 及 CD4 基因與抗原。此外,同工酶分析顯示:ADA,1; ES-D, 1;G6PD, B;GLO-I, 1;PEP-D, 1;PGD, C;PGM1, 1;PGM3, 0。據報導,經電子顯微鏡檢測,這些細胞中未發現病毒顆粒。

一項研究顯示,白藜蘆醇與潑尼松龍的聯合用藥,能以時間依賴性和劑量依賴性的方式誘導 CCRF-CEM 細胞發生凋亡。該聯合治療對 BAx 的過度表達及 BCL2 的下調展現出協同作用。

Fluid renewal
每 3 天
Post-thaw recovery
請讓細胞有至少 48 小時的時間從冷凍過程中恢復。
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。
