BP 預處理的脂肪幹細胞 (BP-preconditioned ADSCs) 可以顯著降低心肌梗塞後的心律不整,並通過 PI3K/Akt/GSK-3β 路徑提升幹細胞的心臟保護效果。BP-preconditioned ADSCs 在心臟移植後對於心臟功能和心臟纖維化改善結果優於未預處理的 ADSCs 。

BP 預處理的脂肪間質幹細胞 (BP-preconditioned ADSCs) 能顯著減少老年大鼠心臟中的 ROS level 和 NLRP3 炎症小體活性,提升脂肪幹細胞 (hADSCs) 的植入效果,以及減少心臟纖維化。BP-preconditioned ADSCs 相比未處理組,心臟纖維化降低達 40%,顯示出其在心肌梗塞後改善幹細胞植入的治療潛力。

BP 預處理的脂肪幹細胞 (BP-preconditioned ADSCs) 能有效調節巨噬細胞表型,通過 PI3K/STAT3 路徑減少心肌纖維化,顯著提高心臟功能與幹細胞植入效果。與普通 ADSCs 相比,BP-preconditioned ADSCs 能顯著提升 M2 型巨噬細胞 (免疫調控) 浸潤和心肌 IL-10 (抗發炎) 的表現量。
