dc.description.abstractThe formation of cranial bone requires the differentiation of osteoblasts from undifferentiated mesenchymal cells. The balance between osteoblast recruitment, proliferation, differentiation and apoptosis in sutures between cranial bones is essential for calvarial bone formation. The mechanisms that control human osteoblasts during normal calvarial bone formation and premature suture ossification (craniosynostosis) begin to be understood. Our studies of the human calvaria osteoblast phenotype and calvarial bone formation showed that premature fusion of the sutures in nonsyndromic and syndromic (Apert syndrome) craniosynostoses results from precocious osteoblast differentiation. We showed that Fibroblast Growth Factor-2 (FGF-2), FGF receptor-2 (FGFR-2) and Bone Morphogenetic Protein-2 (BMP-2), three essential factors involved in skeletal development, regulate the proliferation, differentiation and apoptosis in human calvaria osteoblasts. Mechanisms that induce the differentiated osteoblast phenotype have also been identified in human calvaria osteoblasts. We demonstrated the implication of molecules (N-cadherin, Il-1) and signaling pathways (src, PKC) by which these local factors modulate human calvaria osteoblast differentiation and apoptosis. The identification of these essential signaling molecules provides new insights into the pathways controlling the differentiated osteoblast phenotype, and leads to a more comprehensive view in the mechanisms that control normal and premature cranial ossification in humans.es
