|
The ability of VEGF to be chemotactic for monocytes and to increase the activity of collagenase and plasminogen activator may have implications for renal development and renal disease.
|
| 2 |

|
In humans, the cellular actions of VEGF depend on binding to two specific receptors: Flt-1 and KDR.
|
| 3 |
9621286
|
The aims of this study were: (1) to localize VEGF receptor proteins in human renal ontogenesis; (2) to quantify VEGF binding in human fetal and adult kidney; and (3) to dissect the binding into its two known components: the KDR and Flt-1 receptors.
|
| 4 |

|
The latter aim was achieved by competitive binding of VEGF and placenta growth factor-2, which only binds to Flt-1.
|
| 5 |

|
By double-label immunohistochemistry, VEGF receptor proteins were localized solely to endothelial cells of preglomerular vessels, glomeruli, and postglomerular vessels.
|
| 6 |

|
In developing glomeruli, VEGF receptor protein appeared as soon as endothelial cells were positive for von Willebrand factor.
|
| 7 |
9621286
|
Placenta growth factor-2 displaced VEGF binding in all renal structures by approximately 60%.
|
| 8 |

|
VEGF receptor proteins thus were found only in renal endothelial cells.
|
| 9 |

|
A coexpression of both VEGF binding sites could be shown, with Flt-1 demonstrating the most abundant VEGF receptor binding sites in the kidney.
