目的:探讨黄芪甲苷对人内皮祖细胞(EPC)分泌外泌体及外泌体中微小RNA-126(miRNA-126)表达的影响。方法:取湖南中医药大学第一附属医院妇产科2019年出生的1名足月健康新生儿脐带血，采用密度梯度离心法分离单个核细胞并培养7 d，其间行形态学观察；取第3代细胞，采用CD31免疫磁珠分选法和双荧光染色法鉴定。将鉴定成功的EPC按照随机数字表法分为黄芪甲苷组和磷酸盐缓冲液(PBS)组。黄芪甲苷组细胞加入终质量浓度100 mg/L的黄芪甲苷培养24 h，PBS组细胞加入等体积的PBS培养24 h。培养结束后收集2组细胞培养上清液中的外泌体，采用蛋白质印迹法检测外泌体特征性标志物CD9、CD63和CD81表达，于透射电...

Objective:To investigate the effects of Astragaloside Ⅳ on the secretion of exosomes in human endothelial progenitor cells (EPCs) and the expression of microRNA (miRNA)-126 in exosomes.Methods:The umbilical cord blood from one healthy full-term newborn from the Department of Obstetrics and Gynecology of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine in 2019 was harvested for isolating mononuclear cells by density gradient centrifugation and cultured for 7 days. Morphological observation was performed during t...
