01General information

Description

NCI-H526 細胞系源自一名成人患者的小細胞肺癌(SCLC)。該細胞系廣泛應用於癌症研究,特別是在小細胞肺癌的研究領域;此類癌症以其侵襲性強及預後不良而著稱。 NCI-H526 細胞為探究小細胞肺癌的生物學特性、理解其快速生長與轉移機制,以及開發新的治療策略,提供了關鍵的模型。

NCI-H526 細胞呈現小細胞肺癌特有的圓形、懸浮生長形態。它們表達神經內分泌標記物,例如色格林 A(chromogranin A)和突觸素(synaptophysin),這些標記物是小細胞肺癌的典型特徵。 研究人員利用 NCI-H526 細胞研究與小細胞肺癌相關的遺傳及表觀遺傳變化,包括 TP53 和 RB1 基因的變異——這兩種基因在此類癌症中經常發生突變。 這些細胞亦被用於探索驅動小細胞肺癌進展的訊號傳導路徑,例如 Notch、PI3K/Akt 及 Hedgehog 路徑。在藥物發現與開發過程中,NCI-H526 細胞被用於評估化療藥物、標靶療法及新型治療組合的療效。 NCI-H526 細胞系在小細胞肺癌研究中的關鍵地位,凸顯了其在深化我們對這種棘手疾病理解,以及開發更有效治療方法方面的的重要性。

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。
