01General information

Description

UM-HMC-1 是一種人類黏液表皮樣癌細胞系,源自一名 76 歲非裔美國男性患者的前頰腺原發性唾液腺腫瘤。 該細胞系是密西根大學人類黏液表皮樣癌(UM-HMC)細胞系系列中的其中一個。 UM-HMC-1 攜帶 CRTC1-MAML2 基因融合(亦稱為 MECT1-MAML2),這是大多數黏液表皮樣癌中最具特徵性的致癌事件,源於(11;19)(q21;p13) 染色體轉位所致。此融合基因會活化 CREB 靶基因及 Notch 路徑組分,從而驅動腫瘤增殖與存活。

UM-HMC-1 適用於唾液腺黏液表皮樣癌生物學、CRTC1-MAML2 融合致癌基因訊號傳導、CREB 路徑活化、Notch 路徑失調,以及融合基因驅動癌症的治療靶向研究。 該細胞系可用於藥物敏感性檢測、侵襲與遷移研究,並作為 UM-HMC 多系細胞面板的一部分,用於唾液腺腫瘤生物學的比較特徵分析。

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。
