目的探讨黄芪和当归的主要活性成分黄芪甲苷、芒柄花素、毛蕊异黄酮、毛蕊异黄酮苷和阿魏酸配伍对衰老造血干细胞(HSCs)增殖的影响,并从细胞周期调控研究其作用机制。方法以三丁基过氧化氢(T-BHP)构建小鼠HSCs衰老模型,研究不同质量浓度5种活性成分对HSCs衰老和增殖的影响,寻找可促进细胞增殖的主要活性成分。在此基础上,采用正交试验研究5种活性成分配伍对HSCs衰老和增殖的影响,寻找5种活性成分促进细胞增殖的合理配伍。最后,采用HSCs衰老模型,制备黄芪-当归1∶1配伍含药血浆,设立对照组、模型组、空白血浆组、阿魏酸组、黄芪甲苷组、芒柄花素组、毛蕊异黄酮组、毛蕊异黄酮苷组、活性成分配伍组...

Objective To explore the effects of the combination of main active components of Astragalus membranaceus and Angelica sinensis such as astragaloside IV, formononetin, calycosin, campanulin, ferulic acid on aging hematopoietic stem cells (HSCs), and clarify its mechanism through cell cycle regulation. Methods The aging model of HSCs in mice was established with three butyl hydrogen peroxide (t-BHP) to research the effects of five active components of different concentrations on the senescence and the proliferation of HSCs, and seek the main acti...
