Neural Crest and Placodes provides in-depth coverage of the topic, including information on their critical role in vertebrate development, evolution, and the way defects in their development underlie a wide range of congenital disorders. It delves deep into advances made in our understanding of the mechanisms governing the formation, migration, and differentiation of these two cell populations, also discussing their integration during embryonic development. The text highlights the application of fundamental knowledge in investigating the etiology and pathogenesis of congenital disorders and the ways the data applies to the field of regenerative medicine. Written by leading experts in the field Includes descriptions of the most recent advances in the field Highlights the applications of this knowledge in investigating the etiology and pathogenesis of congenital disorders Explores their usage in the field of regenerative medicine

During evolution the vertebrate head has acquired a number of unique features including specialized paired sense organs and cranial sensory ganglia. These evolutionary novelties arise from discrete thickenings of the head ectoderm known as cranial placodes. They include the adenohypophyseal, olfactory, lens, trigeminal, profundal, otic, epibranchial and lateral line placodes. While distinct in the derivatives and cell types they will form, all cranial placodes originate from a common preplacodal domain surrounding the anterior neural plate. Recent evidence suggests that the induction of this pre-placodal domain and its subsequent subdivision into individual placodes with specific identities is a multi-step process. Here we describe the development of these placodes and their derivatives and summarize recent advances in the characterization of the repertoire of transcription factors underlying their development. We also review recent studies that have started to address the role of several classes of signaling molecules in placode induction and segregation, including Bone Morphogenetic Proteins, Fibroblast Growth Factors and Wnt molecules.

Most of the cranial sense organs of vertebrates arise from embryonic structures known as cranial placodes. Such placodes also give rise to sensory neurons that transmit information to the brain as well as to many neurosecretory cells. This book focuses on the development of sensory and neurosecretory cell types from cranial placodes by introducing the vertebrate head with its sense organs and neurosecretory organs and providing an overview of the various cranial placodes and their derivatives, including evidence of common embryonic primordia. Schlosser discusses how these primordia are established in the early embryo and how individual placodes develop. The latter chapters explain how various placodally derived sensory and neurosecretory cell types differentiate into discrete structures.

In 3-4 week human embryos, the ectoderm covering the head shows considerable re gional differences in both structure and thickness. The temporary appearance of circumscribed areas of relatively thick ectoderm has been observed in embryos of a variety of vertebrates. These areas, discovered by Van Wijhe (1882) in fish embryos, were called placodes by Von Kupffer (1894). These placodes have been studied extensively in embryos of lower vertebrates, probably be cause they can be clearly distinguished in these animals and are readily accessible for experiments. Areas of thick ectoderm in human embryos, first described by Bartelmez and Evans (1926), cover nearly the entire lateral side of the primordium of the head, but do not seem to be identical with the above-mentioned placodes. In human embryos, and in mammalian embryos in general, the placodes are probably part of these larger regions of thick ectoderm. Only incomplete and contradictory data are to be found in the literature on both the origin and development of the areas of thin and thick ectoderm. The relationship between placodes and the larger regions of thick ectoderm has scar cely been studied. In the research described here, some aspects of the problem of the initial develop ment of the ectoderm of the head were studied more closely. In addition, attention was also paid to the general morphology of the young mouse embryo to supplement a previous study (Snell, 1941).

The neural crest is a remarkable embryonic population of cells found only in vertebrates and has the potential to give rise to many different cell types contributing throughout the body. These derivatives range from the mesenchymal bone and cartilage comprising the facial skeleton, to neuronal derivatives of the peripheral sensory and autonomic nervous systems, to melanocytes throughout the body, and to smooth muscle of the great arteries of the heart. For these cells to correctly progress from an unspecifi ed, nonmigratory population to a wide array of dynamic, differentiated cell types—some of which retain stem cell characteristics presumably to replenish these derivatives—requires a complex network of molecular switches to control the gene programs giving these cells their defi ning structural, enzymatic, migratory, and signaling capacities. This review will bring together current knowledge of neural crest-specifi c transcription factors governing these progressions throughout the course of development. A more thorough understanding of the mechanisms of transcriptional control in differentiation will aid in strategies designed to push undifferentiated cells toward a particular lineage, and unraveling these processes will help toward reprogramming cells from a differentiated to a more naive state.

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.
