Skeletal tissue is composed of multiple cell-types including bone-forming osteoblasts, bone-resorption osteoclasts, and joint-maintaining chondrocytes. To establish the strategy for bone regeneration and treatments of skeletal disorders, understanding the mechanisms underlying cell-fate specification and differentiation of skeletal cell-types is necessary. We aim at identifying gene regulatory networks in skeletal development and skeletal repair through epigenetics, gene regulatory analysis and single-cell analysis with next-generation sequencing. We also try to understand cell-cell interaction networks among multiple cell-types in bone tissues by focusing signaling network analysis. Recently, we further explore human skeletal development and species comparison analysis by utilizing a modeling of human skeletal development with pluripotent stem cells and clinical bone samples. Through these analyses, we identify key mechanisms of human skeletal development and repair. We further develop regenerative methods to manipulate the mechanisms by integrating with biomaterials.


Current projects are listed as follow:

  • Identifying the dynamics of epigenome and gene regulation in skeletal development and repair by utilizing omics analysis, single-cell analysis and bioinformatics
  • Development of screening tools for identifying mechanisms underlying skeletal development and pathology of skeletal disorders by utilizing single-cell analysis, molecular barcode and genome editing methods

  • Modeling human skeletal development of disorders by utilizing pluripotent stem cells

  • Development of implant devices for tissue regeneration by integrating high-performance biomaterials and signaling molecules stimulating tissue repairing processes.

  • Identifying novel therapeutic targets for hip fractures and osteoporosis
