Outline of Final Research Achievements |
Analysis of the μCT image of achondroplasia (Ach) model mice revealed midfacial hypoplasia in the sagittal direction and foramen magnum stenosis similarly to human. Both hypertrophic chondrocyte layers and proliferating chondrocyte layers the cartilage of the skull base of the Ach mice were narrowed, and early ossification with angiogenesis and apoptosis was found in the center of the cartilage of the skull base. The midfacial hypoplasia and the foramen magnum stenosis in the Ach mice could be significantly improved by the increase in the blood concentration of CNP. It was suggested that administration of CNP could improve the abnormalities of craniofacial morphology found in achondroplasia by promoting endochondral ossification in the cranial cartilage.
