Research on embryonic cephalic neural crest cells and paraxial mesoderm is providing new information regarding vertebrate craniofacial morphogenesis. Based on recent results, a reevaluation of the roles these embryonic populations play in the development of the head has been undertaken. The following discussion will consider the possible impact of these data on our understanding of craniofacial morphogenesis. The neural crest has attracted the interest of embryologists since before the turn of the century. This attention resulted from the apparent abilities of these ectodermally derived cells to migrate extensively within the embryo, and to give rise to a diverse and heterogeneous array of tissues, including peripheral sensory and autonomic ganglia, adrenal medullary and other secretory populations, craniofacial skeletal and connective tissues, Schwann cells and melanocytes (reviewed by Horstadius, 1950; Weston, 1970; Le Douarin, 1975, 1980,1983; Noden, 1978a, 1980,1982). The recent renewed interest in this ectomesenchymal population has been brought on in part by improved methods of labeling crest cells for transplantation in avian embryos (Weston, 1963; Le Douarin, 1969). In addition, many advances have been made both in biochemical methods for analyzing the extracellular milieu surrounding developing crest cells (Newgreen and Gibbons, 1982; Thiery et al., 1982b; Rovasio et al., 1983; earlier work reviewed by Weston, 1980, 1982) and in the ability to maintain them and promote their cytodifferentiation in vitro (Ziller et al., 1983; Kahn and SieberBlum, 1983; earlier work reviewed by Patterson, 1978; Bronner-Fraser and Cohen, 1980). While the focus of this discussion will be on in vivo analyses, each of these approaches has contributed significantly to our current understanding. Cephalic paraxial mesoderm has received considerably less attention. The scanning electron microscopic observations by Meier (1981; Anderson and Meier, 1981) have shown that avian cephalic paraxial mesoderm located rostra1 to the first somite is not lacking in metamerism, but rather is partially segmented in the form of seven somitomeres. These condensations, which closely resemble immature somites (Meier and Jacobson, 19821, are found in mammals, reptiles, and amphibians as well (Meier and Tam, 1982; Meier and Packard, personal communication). Experimental analyses of the role of somitomeres and occipital somites in craniofacial development will be discussed.
