01General information

Description

HCC1187 是一種從成人患者原發性導管型乳腺腫瘤建立的人類乳腺癌細胞系。該細胞系呈現三陰性表型,不表達雌激素受體(ER)、黃體酮受體(PR)及 HER2,此為基底樣乳腺癌的特徵。 HCC1187 屬於一套旨在反映乳癌分子多樣性的細胞系組合,並已在多項大規模基因組與蛋白質體學研究中經過廣泛分析,包括《癌症細胞系百科全書》(CCLE)及與《癌症基因組圖譜》(TCGA)對齊的分析。

該細胞系呈現出常見於高分級乳腺腫瘤的複雜基因組改變,例如拷貝數變異及高體細胞突變負荷。 蛋白質組學分析顯示,HCC1187 的蛋白質組學特徵與基底樣乳腺腫瘤一致,包括與基底上皮細胞相關的細胞角蛋白表達升高,以及管腔標記物水平較低。 定量蛋白質體學分析亦顯示,根據路徑層級的蛋白質表達,HCC1187 與其他三陰性乳癌(TNBC)細胞系歸為同一群組,這表明其與 DNA 損傷修復、細胞週期進展及凋亡相關的路徑存在調控失調。 這些特性使 HCC1187 成為研究 TNBC 生物學以及測試針對基底樣或 BRCA1 缺失型乳腺癌亞型的靶向治療的寶貴模型。

HCC1187 亦已被納入乳癌的全面性突變研究中,有助於理解突變頻率模式,以及驅動突變與乘客突變的整體圖景。研究顯示,儘管個別腫瘤攜帶眾多突變,但僅有其中一部分會顯著促進癌症進展。 在 HCC1187 中,已鑑定出數種此類驅動突變及路徑改變,使其成為探索腫瘤發生遺傳基礎及開發個人化治療方案的關鍵模型。

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。
