infusion of umbilical cord versus bone marrow derived mesenchymal stem cells to evaluate cytokine suppression.

Conditions: Endothelial Dysfunction; Metabolic Syndrome; Chronic Inflammation

Summary: this study is to compare the safety and efficacy of ucmscs and bmmscs administered intravenously in patients to evaluate cytokine suppression in patients with chronic inflammation. cells administered via intravenous infusion (iv) and will be tested in 37 patients in two phases (pilot and randomized).
