The activation of serum hepatocyte growth factor in acute renal failure

Bone morphogenetic proteins in development and homeostasis of kidney

Bone morphogenetic proteins play a key role in kidney development and postnatal function. The kidney has been identified as a major site of bone morphogenetic protein (BMP)-7 synthesis during embryonic and postnatal development, which mediates differentiation and maintenance of metanephric mesenchyme. Targeted disruption of BMP-7 gene expression in mice resulted in dysgenic kidneys with hydroureters, causing uremia within 24h after birth. Several experimental animal models of acute and chronic renal injury have all unequivocally shown beneficial effect of BMP-7 in ameliorating the severity of damage by preventing inflammation and fibrosis. Apart from the beneficial effect on kidney disease itself, BMP-7 improves important complications of chronic renal impairment such as renal osteodystrophy and vascular calcification.
