The glomerular endothelial cells are unique both in location and anatomy compared to most other endothelial cells throughout the body. The absence of a diaphragm with retention of a basement membrane and fenestrations enable these uniquely situated cells to have a key role in filtration performed by the kidney. Interaction with other glomerular cells such as the podocytes and mesangial cells, as well as with circulating and infiltrating inflammatory cells, contribute to the final impact of the glomerular endothelial cells on maintenance of body fluid homeostasis and modulation of disease. Thus, endothelial cells contribute to hemodynamic function, reactive oxygen stress, regulate the balance between pro-thrombotic and anti-thrombotic forces, and importantly, contribute to fibrosis, the key injury of progressive chronic kidney disease. Repair of endothelial cell damage and restoration of segmentally sclerosed glomeruli are key areas considered for intervention in chronic kidney disease. This review will focus on the structure, function, and interplay of endothelial cells with other glomerular cells and systemic factors, their impact on renal disease and give rationale for possible intervention that may forestall progressive injuries.
