間充質(zhì)干細胞的細胞外囊泡減輕小鼠缺血再灌注腎損傷的相關研究
發(fā)布時間:2022-10-08 18:36
背景與目的:腎缺血再灌注損傷(Renal Ischemia/Reperfusion Injury)是引起急性腎損傷(acute kidney injury,AKI)的主要原因之一。間充質(zhì)干細胞(mesenchymal stem cells,MSCs)的細胞外囊泡(Extracellular Vesicles,EVs)應用于多種疾病模型的干預治療上,其主要作用中包括減輕氧化應激和恢復線粒體功能,但其中關鍵有效成分尚不明確。我們嘗試應用人臍帶間充質(zhì)干細胞的細胞外囊泡對小鼠腎缺血再灌注損傷進行治療的驗證;同時應用蛋白組學和生物信息學分析,篩選出細胞外囊泡中可能起治療作用的關鍵組份,希望獲得的結果為未來深入研究打下基礎。方法:從人臍帶分離華通膠部分原代培養(yǎng)間充質(zhì)干細胞,培養(yǎng)至細胞生長80%-90%融合時更換無血清培養(yǎng)基,24小時后收取條件培養(yǎng)基利用超速離心法提取細胞外囊泡。對提取獲得的細胞外囊泡進行透射電子顯微鏡(Transmission Electron Microscope,TEM)和納米流式檢測儀(NanoFCM)鑒定。建立左腎缺血25min,右腎切除的小鼠模型。隨機分為未IR損傷組,I...
