There is growing evidence suggesting that glomerular endothelial cell proliferation and angiogenesis may be responsible for the pathophysiological events in the early stage of diabetic nephropathy. This study was designed to investigate the factors related to glomerular endothelial cell proliferation and glomerular angiogenesis and assess the effect of propyl gallate on preventing these disorders in diabetic rats. We found that glomerular hypertrophy, glomerular mesangial matrix expansion, and albuminuria were significantly increased in DN rats. CD31+ endothelial cells significantly increased in glomerulus of diabetic rats. Double immunofluorescence staining showed some structurally defective vasculus tubes in glomerulus. Real-time PCR and western blot demonstrated the glomerular eNOS expression remained at the same level, while remarkable decreased NO productions and suppressed eNOS activities were observed in diabetic rats. Treatment with propyl gallate improved glomerular pathological changes, reduced endothelial cell proliferation, decreased albuminuria, and restored eNOS activity, but did not alter eNOS expression. These data suggest that endothelial cell proliferation and immature angiogenesis may be the contributors to progression of DN. Propyl gallate is a potential novel therapeutic agent on prevention of diabetic nephropathy.

To enable the study of glomerular endothelial cell functions and interactions with other glomerular cells, bovine glomerular capillary endothelial cells were established in culture. Selective media were used to facilitate endothelial cell proliferation and to suppress glomerular mesangial cell growth. Glomerular endothelial cells were separated from other cell types by fluorescence-activated cell sorting or, alternatively, by cloning. Glomerular endothelial cells expressed angiotensin I-converting enzyme and factor VIII activity and acetylated LDL uptake, properties generally held to be specific for endothelial cells. Proliferation of subconfluent glomerular endothelial cells was stimulated by basic fibroblast growth factor and, in the presence of heparin sodium, by acidic fibroblast growth factor. Platelet-derived growth factor was without effect on glomerular endothelial cell proliferation. Coculture with mesangial cells markedly inhibited proliferation of subconfluent glomerular endothelial cells. By contrast, medium conditioned by confluent glomerular endothelial cells markedly enhanced proliferation of subconfluent glomerular endothelial cells. These findings suggest that glomerular endothelial cell growth is under autocrine and paracrine control.
