Injury to a target organ can be sensed by bone marrow stem cells that migrate to the site of damage, undergo differentiation, and promote structural and functional repair. This remarkable stem cell capacity prompted an investigation of the potential of mesenchymal and hematopoietic stem cells to cure acute renal failure. The model of renal injury induced in(More)
Human amniotic fluid stem (hAFS) cells, a novel class of broadly multipotent stem cells that share characteristics of both embryonic and adult stem cells, have been regarded as promising candidate for cell therapy. Taking advantage by the well-established murine model of acute kidney injury (AKI), we studied the proregenerative effect of hAFS cells in(More)
Kidney repair from injury is a major focus of interest for research, both clinical and basic, in the field of acute renal failure. This is so because very little progress has been made during the past several years to improve mortality in hospitalized patients with acute renal failure despite the unique potential of the kidney for complete structural and(More)
The possibility that proteinuria may accelerate kidney disease progression to end-stage renal failure has received support from the results of increasing numbers of experimental and clinical studies. Evidence indicating that this process occurs through multiple pathways, including induction of tubular chemokine expression and complement activation that lead(More)
Renin-angiotensin system (RAS) inhibitors are effective in reducing renal disease progression in early diabetic nephropathy, but they provide imperfect protection at a later stage. Due to the pivotal role of transforming growth factor-beta (TGF-beta) in the pathogenesis of diabetic kidney disease, this study tested the effect of simultaneously interrupting(More)
Transplantation of bone marrow mesenchymal stem cells (BM-MSC) or stromal cells from rodents has been identified as a strategy for renal repair in experimental models of acute kidney injury (AKI), a highly life-threatening clinical setting. The therapeutic potential of BM-MSC of human origin has not been reported so far. Here, we investigated whether human(More)
Currently available monoclonal antibodies against the B cell surface antigen CD20 have been employed to explore whether specific inhibition of B cells may help improve the outcome of idiopathic membranous nephropathy (IMN) and may avoid the side effects of steroids and immunosuppressants. This prospective, observational study evaluated the 1-yr outcome of(More)
Chronic diseases of the kidney have a progressive course toward organ failure. Common pathway mechanisms of progressive injury, irrespectively of the etiology of the underlying diseases, include glomerular capillary hypertension and enhanced passage of plasma proteins across the glomerular capillary barrier because of impaired permselective function. These(More)
In search for new sources of mesenchymal stem cells (MSCs) for renal repair in acute kidney injury (AKI), we investigated the potential of human cord blood (CB)-MSCs to cure mice with AKI. Infusion of CB-MSCs in immunodeficient mice with cisplatin-induced AKI ameliorated both renal function and tubular cell injury, and prolonged survival. Transplanted(More)
Cell therapy with Multipotent Mesenchymal Stromal Cells (MSC) holds enormous promise for the treatment of a large number of degenerative and immune/inflammatory diseases. Their multilineage differentiation potential, immunoprivilege and capacity of promoting recovery of damaged tissues coupled with anti-inflammatory and immunosuppressive properties are the(More)
