黄芪多糖对2型糖尿病患者外周血内皮祖细胞增殖及NO生成的影响
Effect of astragalus polysaccharides on proliferation and NO production of endothelial progenitor cells from peripheral blood in patients with type 2 diabetes
摘要
Abstract
Objective To observe the effect of astragalus polysaccharides ( APS) on proliferation and nitric oxide (NO) production of endothelial progenitor cells ( EPCs) from peripheral hlood in patients with type 2 diabetes mellitus (T2DM).Methods Total mononuclear cells were isolated by Ficoll density gradient centrifugation.After 7 days of culture, EPCs were characterized , the effect of APS on EPCs proliferation was ohserved.EPCs were treated with various concentration and different time culture of APS, then treated with LY294002 ( PI3K inhibitor) , then the NO level was measured.Results APS could promote the proliferation of EPCs in T2DM, and increase the endothelial NO production in a dose and a time-dependent manner.LY294002 prevented the NO production induced by APS.Conclusions The rat tail collagen can be a more cheaper replacement of the fibronectin to culture the EPCs from peripheral blood in patients with T2DM.Treatment with APS can increase the NO production and markedly promote the proliferation of EPCs in T2DM,LY294002 prevents the NO production induced by APS.关键词
