Differential FGF ligands and FGF receptors expression pattern in frontal and parietal calvarial bones.

ABSTRACT: The mammalian skull vault consists mainly of 5 flat bones, the paired frontals and parietals, and the unpaired interparietal. All of these bones are formed by intramembranous ossification within a layer of mesenchyme, the skeletogenic membrane, located between the dermal mesenchyme and the meninges surrounding the brain. While the frontal bones are of neural crest in origin, the parietal bones arise from mesoderm. The present study is a characterization of frontal and parietal bones at their molecular level, aiming to highlight distinct differences between the neural crest-derived frontal and mesodermal-derived parietal bone. We performed a detailed comparative gene expression profile of FGF ligands and their receptors known to play crucial role in skeletogenesis. This analysis revealed th
