01General information

Description

UM-HMC-3A 是一種人類黏液表皮樣癌細胞系,源自一名成人患者在原發性病灶接受手術切除數年後,其唾液腺腫瘤發生局部復發的病例。 該細胞系屬於一對配對細胞系(UM-HMC-3A 與 UM-HMC-3B)的一部分,均源自同一位患者,分別代表疾病進展的不同階段,即局部復發與淋巴結轉移。 UM-HMC-3A 細胞在體外呈現穩定的上皮樣形態,形成鵝卵石狀單層,並在長期培養中保持一致的生長特性,據報導已成功傳代超過 100 代。 短串聯重複序列分析證實其源自患者腫瘤,並排除交叉污染的可能性,這支持了其作為模型系統的可靠性。

UM-HMC-3A 在體內展現出致瘤能力,當植入免疫缺陷小鼠體內時會形成異種移植腫瘤。這些異種移植腫瘤再現了原始患者腫瘤的關鍵組織病理學特徵,包括存在表皮樣細胞群和產生黏液的細胞群。 過碘酸-席夫(PAS)染色顯示其黏多醣的產生量與人類腫瘤相當,表明其功能性分化得以保留。 相較於其轉移性對應株(UM-HMC-3B),UM-HMC-3A 的腫瘤形成速度通常較慢,且初期植入成功率較不穩定,這反映了局部復發與轉移性進展之間的生物學差異。 UM-HMC-3A 提供了一個寶貴且特徵明確的模型,可用於研究唾液腺黏液表皮樣癌的腫瘤復發、上皮分化及治療反應。

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.

06Quality 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。
