Outline of Final Research Achievements

Mesenchymal stem cells can differentiate into various cell types. Particularly the regulatory mechanisms of the balance between differentiation to adipocytes and osteoblasts are closely linked to the pathogenesis of metabolic syndrome and osteoporosis. We performed detailed RNA expression analysis using differentiating cells. Differential expression of each exon and ncRNAs are comprehensively analyzed using exon array, miRNA array and RNA-sequencing. As a result, we detected various RNA variants of other genes and ncRNAs that are differentially expressed between both types of differentiation. We estimate that specific RNA variants and ncRNAs which regulate the differentiation are involved in those differentially expressed RNA variants, and currently the experiments for their validation are underway
