Endogenous antiangiogenic factors in (a) glomerulus (podocyte and glomerular endothelial cell) and (b) tubulointerstitium (tubular epithelial cell and peritubular capillary endothelial cell). See text for detailed physiological and pathological roles of each factor in kidney. Abbreviations: GBM, glomerular basement membrane; TBM, tubular basement membrane; VEGF-A, vascular endothelial growth factor-A; VEGFR2, VEGF receptor-2; sFlt1, soluble fms-related tyrosine kinase 1; PEDF, pigment epithelium-derived factor; VASH1, vasohibin-1.
