| Outline of Final Research Achievements |
The therapeutic effect of microRNA (miRNA) which play a role in angiogenesis on injury in orthpaedic field. Especially, we focused on secreted miRNAs from cell. Peripheral blood mononucleated cells were isolated from healthy subjects, and cultured. Stimuli by hypoxia environment was given during culture, and the medium with or without hypoxia were analyzed using miRNA microarray. Several miRNAs showed specific expression pattern, and over expression of these miRNAs in fibroblast induced cell proliferation. In vivo, administration of miRNA related to angiogenesis into rat model of meniscus, tendon injury and atrophic non-union showed successful results.
