01General information

Description

HEL 92.1.7 細胞系具有自發分化為紅細胞前體樣細胞的能力,可在體外模擬紅細胞成熟的某些方面。 這項特性使其特別適用於研究紅細胞分化過程,以及與造血相關的基因表達調控。其自發分化能力提供了一項獨特優勢,可藉此研究驅動紅細胞前體成熟的內在途徑與機制,而無需添加外部分化誘導劑。

此外,可透過添加如 TPA (12-O-十四碳酰基-佛波酯-13-乙酸酯)和PMA(佛波酯肉豆蔻酸酯)等佛波酯類物質,這些物質已知可誘導巨噬細胞樣分化。 這種誘導成巨噬細胞樣細胞的分化,將 HEL 92.1.7 細胞系的應用範圍擴展至紅細胞研究之外,使研究人員能夠探索並理解造血細胞的可塑性,以及在何種條件下可以重新導向細胞譜系承諾與細胞身份。 此類研究對於制定旨在操控細胞命運的治療策略至關重要,這些策略可應用於再生醫學及癌症治療。

Supplements
在培養基中加入 10% 經熱滅活的胎牛血清
Dissociation reagent
Accutase
Subculturing
將懸浮細胞收集至 15 毫升試管中,並用不含鈣和鎂的 PBS 輕柔地洗滌貼壁細胞(T25 培養瓶使用 3-5 毫升,T75 培養瓶使用 5-10 毫升)。 加入 Accutase(T25 培養瓶使用 1–2 毫升,T75 培養瓶使用 2.5 毫升),確保完全覆蓋細胞層。讓細胞於室溫下孵育 10 分鐘。 孵育完成後,將懸浮細胞與貼壁細胞合併並進行離心。離心後,小心地將細胞沉澱重新懸浮,並將細胞懸液轉移至裝有新鮮培養基的新培養瓶中。
Fluid renewal
每週 2 至 3 次
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。
