| Outline of Final Research Achievements |
Glycogen is a storage form of glucose within mammalian cells and plays a major role in energy metabolism. Temporary glycogen storage has been observed in the cell differentiation stage during organ development, and understanding the glycogen metabolism that underlies various cell dynamics is essential for developing strategies for organ regeneration. Here, we investigated glycogen metabolism in murine tooth development. We demonstrated that glycogen metabolism is an essential pathway for dental cell differentiation. Next, we evaluated the effect of enzymatically synthesized glycogen (ESG) on osteogenesis as well as odontogenesis using in vitro and in vivo experimental model of mice. As results, ESG stimulated the cell growth and differentiation of dental cells and accelerated the growth of tooth explants in vitro. In conclusion, ESG could be a useful stimulant for osteogenesis and odontogenesis.
