Research ProjectsF1) Analysis of the function of extracellular matrix molecules, especially collagen
The tissues and organs in the organisms are formed and maintained by the interaction between various cells and the surrounding extracellular matrix. It is important to understand the roles of the extracellular matrix as well as the cells in order to elucidate the mechanisms in the physiological and pathological conditions of an organism. Specifically, we are focusing on the regulation of collagen genes and their functions.
2) Search for the new substances in natural materials and the analysis of their biological function
There are many natural substances. Some of them have a biological function for maintaining the homeostasis of the individual. Apart from drugs, those substances maintain and improve the individualfs daily health conditions. We are focusing on identifying new substances and elucidating their functions.
3) Search for tissue specific differentiation factors in mesenchymal stem cells and the analysis of their  function
The cells in bone, cartilage, skin, muscle and fat are differentiated from mesenchymal stem cells. The mechanisms for their differentiation remain unclear in spite of extensive study. The extracellular matrix is involved in some steps of these mechanisms. We are therefore focusing on identifying the factors can eventually be applied for use in the field of regenerative medicine.
