| Outline of Final Research Achievements |
sp7/osterix is a zinc finger transcription factor that is essential for osteoblast differentiation in mammals. To verify the characteristic features of osteoblast-lineage cells in teleosts, medaka sp7 mutants were established using a transcription activator-like effector nuclease (TALEN) genome editing system. These mutants showed severe defects in the formation of skeletal structures, indicating that sp7/osterix gene is essential for skeletal development in medaka. In addition, the present study revealed that type X collagen a1 a (col10a1a)-positive cells are osteoblast-like cells and sp7/osterix gene expression in osteoblast-lineage cells is required for differentiation into mature osteoblasts to form the skeletal structures.
