New developments in bone formation.
Two independent strategies have established that the transcription factor, Cbfa1, is a key regulator of both osteoblast differentiation and osteoblast-specific gene expression. Gene targeting experiments in mice have also shown that haploinsufficiency of Cbfa1 expression causes symptoms reminiscent of the Cleidocranial dysplasia syndrome (CCD), a heritable disorder of the skeleton. Direct analysis of the Cbfa1 gene in CCD families has revealed a direct correlation between mutations in this gene and disease phenotype.
