Craniofacial Development The Tissue And Molecular Interactions That Control Development Of The Head

Craniofacial development is a multistep and intricate process initially involving a number of inductive interactions that control neural and neural crest development, which are followed by a series of epithelial-mesenchymal interactions that control outgrowth, patterning, and skeletal differentiation. Certain aspects of craniofacial development are unique developmental processes in higher vertebrates. First, in higher vertebrates the cranial neural crest, in contrast to the trunk neural crest, gives rise to the skeletal structures. These skeletal elements include those comprising mem brane bone and secondary cartilage, which with the exception of the clavicle are tissue types found exclusively in the head in higher vertebrates. Second, with the exception of the tongue, the origin of the musculature is distinct from other regions of the body. The body and tongue muscles are formed from the segmented epithelial somites whilst the head musculature is formed from unsegmented paraxial and prechordal mesoderm. Furthermore, the signalling cascades that control myogenic differentia tion appear to be distinct as determined by gene expression and the response of myogenic cells to growth factors. Finally, the neurogenic placodes, which give rise to the sensory organs and some cranial ganglia, are only found in the head. Over recent years, there have been significant advances in our knowledge of the molecular proc esses that control craniofacial development in a number of animal models. This has given insight into the genes that control many aspects of head development from the initial induction of the head to the final stages of differentiation.

"Over the past twenty years craniofacial biology has been revolutionized by major developments in our understanding of the cellular, molecular and genetic mechanisms underlying embryonic development. Many of these advances have been based on animal models, most notably the fruitfly Drosophila, the chick and the mouse. Since these developmental processes have been highly conserved during evolution, this information is relevant not only to understanding normal human development but also to understanding how genetic mutations produce particular malformations or inherited diseases. This book incorporates these discoveries into traditional morphological description of craniofacial development, and in a form accessible to clinicians with an interest in the head and neck." --book cover.
