| Outline of Final Research Achievements |
Chondroitin sulfate proteoglycan (CSPG) is one of major extracellular matrices and is known to play an important part in organogenesis. To elucidate the role of CS in tooth and craniofacial development and regeneration, we analyzed the craniofacial morphology in chondroitin sulfate synthetic enzyme knockout (CSKO) mice. In normal odontogenesis, the CS chain localized in immature dental papilla and periodontal ligament. In the differentiated dental pulp, CS chain restricted to the apex of tooth root. In CSKO mice, some of KO mice exhibited severe facial developmental defect. Although most of CSKO mice showed normal postnatal development, they exhibited the deformation of cranial bone and malocculusion. These results suggest that CS chain is necessary for normal tooth and craniofacial morphogenesis.
