Effect of Astragalus Membranaceus on the Interaction of Mesangial Cells and Endothelial Cells / 中国中医药信息杂志

ABSTRACT

Objective To study the effect of astragalus membranaceus on the interaction of mesangial cells and endothelial cells in the media of high glucose and lysophosphatidylcholine. Methods The model of intercellular interaction between endothelial cells and mesangial cells of diabetic nephropathy was established and divided into 4 groupscontrol, mannitol, high glucose and lysophosphatidylcholine, intervented with astragalus membranaceus. Endothelial cells and mesangial cells were co-cultured in DMEN with or without astragalus membranaceus in high glucose and lysophosphatidylcholine media up to 24 hours. The level of collagen Ⅳ and fibrocentin were determined by enzyme linked immunosorbent assay in the culture media. Results The level of collagen Ⅳ and fibrocentin of high glucose and lysophosphatidylcholine group was markedly higher than that of control group in co-culture and the ordinary monolayer cell culture (P
