Hypoxia and Inflammatory Injury in Human Renovascular Hypertension
Completed · Phase 1
Conditions studied: Renal Artery Stenosis, Ischemic Nephropathy, Renovascular Disease, Chronic Kidney Disease
In brief
Current treatments for ARAS based on restoring blood flow alone have been unsuccessful at recovering kidney function. For this reason we are studying a stem cell product called "mesenchymal stem cells" or MSC. Mesenchymal stem cells (MSC) are grown from a person's own fat tissue (obtained as a fat biopsy) and infused back into the patient's own kidney. This study is also being done to determine if the MSC infusion prior to percutaneous transluminal renal angioplasty with stenting (PTRA) further enhances changes in single kidney blood flow and restoration of kidney function, as well as to assess the relationship between MSC dose and measures of kidney function.
