Occlusive renovascular disease caused by atherosclerotic renal artery stenosis
(ARAS) elicits complex biological responses that eventually lead to loss of
kidney function. Recent studies indicate a complex interplay of oxidative stress,
endothelial dysfunction, and activation of fibrogenic and inflammatory cytokines
as a result of atherosclerosis, hypoxia, and renal hypoperfusion in this
disorder. Human studies emphasize the limits of the kidney adaptation to reduced
blood flow, eventually leading to renal hypoxia with activation of inflammatory
and fibrogenic pathways. Several randomized prospective clinical trials show that
stent revascularization alone in patients with atherosclerotic renal artery
stenosis provides little additional benefit to medical therapy once these
processes have developed and solidified. Experimental data now support developing
adjunctive cell-based measures to support angiogenesis and anti-inflammatory
renal repair mechanisms. These data encourage the study of endothelial progenitor
cells and/or mesenchymal stem/stromal cells for the repair of damaged kidney
tissue.
