| Outline of Final Research Achievements |
Mesenchymal stem cells (MSCs) are present in all adult tissues including bone marrow and skeletal muscle. Aim of this study was to investigate stem cell properties of MSCs from skeletal muscle for development of a novel angiogenic therapy in peripheral artery disease (PAD). Properties of proliferation and differentiation in the MSCs were similar to bone marrow MSCs, whereas pro-angiogenic property in muscle MSCs was superior to the bone marrow cells. The angiogenic potential was activated by erythropoietin. Fibroblast growth factor (FGF)-23 induced cellular senescence of the muscle MSCs via oxidative stress/p53/p21 pathway. PAD is prevalent in patients with chronic kidney disease (CKD). Thus, results of this investigation suggested that disruption of productive balance of those factors in the CKD deteriorated the muscle MSC function. Activation of muscle MSCs via regulation of CKD-related cytokines may become a new therapeutic strategy for PAD.
