Outline of Final Research Achievements |
The comprehensive analysis of miRNA and mRNA expression were performed using the femoral head that was obtained from the patient with osteonecrosis of femoral head. I evaluated the ability of osteogenic proliferation and vascularization using miRNA candidates, and lined up four candidates that ware considered to be useful for angiogenesis and bone regeneration. I also revealed that microRNA can be transfected into cells in other cultured cells such as myoblasts with exosomes that contained synthetic miRNA that was obtained from microRNA transfected mesenchymal stem cells, and microRNA increased density-dependently.
