| Research Abstract |
We generated transgenic medaka fish expressing mouse Fra-1 in osteoblasts to determine cell-autonomous function of Fra-1 in osteoblasts in vivo. Alizarin complexone staining and micro-computed tomography revealed that Fra-1 transgenic medaka showed lower bone mineral density than wild-type controls. These data suggest that Fra-1 expression in osteoblasts impairs bone mineralization not only in mice but also in medaka.
