Brief Summary:
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.

Detailed Description:
These studies include participation by human subjects using a 3-day inpatient CRU protocol at St. Mary's Hospital. Studies include formal measurement of blood and urinary markers of kidney function, BOLD MR and multidetector CT scanning. Forty-two non-diabetic patients between 40 and 80 years of any race or ethnicity will be recruited. All will have hypertension (defined as BP≥140/90 mmHg or ongoing antihypertensive drug therapy) but will have less than 180 mmHg to be included (with or without drug therapy). These subjects will be free of cardiovascular events within 3 months and will not have implanted electrical devices, such as a pacemaker or defibrillator. All patients will have identified large vessel renovascular disease (RVD) for Aims 1, 2 and 3. At least 10% of these subjects will be of African-American descent (self-identified) and recruited in collaboration with the University of Mississippi under the direction of Dr. Luis Juncos and the University of Alabama under the direction of Dr. David Calhoun. For completion of Aims 2 and 3, a three-day evaluation will be repeated between three and four months later, and ongoing safety and imaging studies will be performed up to 24 months after MSC administration. Participants in these protocols will undergo transvenous kidney biopsy under the direction of Drs. McKusick and Misra and their colleagues in Interventional Radiology. All subjects for these studies will complete the research plan at Mayo Clinic, Rochester, Minnesota.
