Conditional inactivation of fgfrl caused different phenotypes displaying in different cells or specific organs and revealed some novel functions of FGFR1 in bone development. Fgfrl mutation mainly induced 2 types of human skeletal diseases, craniosynostosis syndrome and dysplasias. Similar mutation of fgfrl in mouse model just mimicked the phenotype that happened in human. These fa- cilitate the investigation on the underlying mechanism of the diseases. Here we mainly focused on the ad- vance of FGFR1 function in the bone development and its mutation caused skeletal diseases.展开更多
