Allogeneic Mesenchymal Human Stem Cells Infusion Therapy for Endothelial DySfunctiOn in Diabetic Subjects

Inclusion criteria

• Be ≥ 21 and < 90 (inclusive) years of age.
• Provide written informed consent.
• Have endothelial dysfunction defined by impaired flow-mediated vasodilation (FMD <7%).
• Have an ejection fraction > 45% by gated blood pool scan, two- dimensional echocardiogram, cardiac MRI, cardiac CT or left ventriculogram within the prior 3 months.
• Have Diabetes mellitus type 2 documented by hemoglobin adult type 1 component (A1C) > 7% or on medical therapy for diabetes.
• Females of childbearing potential must use two forms of birth control for the duration of the study. Female subjects must undergo a blood or urine pregnancy test at screening and within 36 hours prior to infusion.

• Have Lymphadenectomy or Lymph node dissection in the right arm.
• Be an organ transplant recipient or have a history of organ or cell transplant rejection.
• Have a clinical history of malignancy within the past 5 years (i.e., subjects with prior malignancy must be disease free for 5 years), except curatively- treated basal cell or squamous cell carcinoma, or cervical carcinoma.
• Have a condition that limits lifespan to < 1 year.
• Have a history of drug or alcohol abuse within the past 24 months.
• Be on chronic therapy with immunosuppressant medication, such as corticosteroids or Tumor Necrosis Factor - alpha (TNFα) antagonists.
