Further study details as provided by Mayo Clinic:
Primary Outcome Measures:
- Renal blood flow and function in the treated kidneys. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]Individual kidney blood flow, measured by multidetector CT contrast transit times, will be measured before and after MSC infusion.
Secondary Outcome Measures:
- Level of kidney function. [ Time Frame: 2 years ] [ Designated as safety issue: No ]Level of kidney function will be assessed as glomerular filtration rate by iothalamate clearance. Tissue oxygenation within each kidney will be measured by Blood Oxygen Level Dependent (BOLD) magnetic resonance.
Other Outcome Measures:
- Blood pressure levels. [ Time Frame: 2 years ] [ Designated as safety issue: No ]Blood pressure will be assessed by oscillometric measurement.

Experimental: Arterial infusion of autologous mesenchymal stem cells
Patients will undergo a subcutaneous fat biopsy for expansion of mesenchymal stromal (stem) cells (MSC) in the Human Cell Therapy Laboratory. Patients will be admitted to the inpatient Clinical Research Unit of the Mayo Clinic Center for 3 days prior to treatment, for pre-infusion tests. Renal angiography will be performed to deliver a single intra-arterial dose of MSC's into one affected kidney. Patients will be observed for 24 hours for acute adverse events. Patients will have remote visits at 1 week, 4 weeks,8 weeks, and 6 months. At 3 months, patients will return for repeat evaluation of kidney function, blood flow and structural alterations within the clinical research unit at St. Mary's Hospital, Rochester, Minnesota. Thereafter, health assessment and blood draws will be repeated at 12 and 24 months with urinary cytology and MRI.
