Animal embryos need to specify different cell types, and the genetic functions that provide
such controls are easy to comprehend since they result in the formation of overtly …

Organization and Evolution of Hox/HOM-C Complexes The genomic structural and
organizational similarities between vertebrate Hox and Drosophila HOM-C complexes …

The Drosophila gene eyeless (ey) encodes a transcription factor with both a paired domain
and a homeodomain. It is homologous to the mouse Small eye (Pax-6) gene and to the …

During vertebrate craniofacial development, neural crest cells (NCCs) contribute much of the
cartilage, bone and connective tissue that make up the developing head. Although the initial …

The neural crest (NC) yields pluripotent cells endowed with migratory properties. They give
rise to neurons, glia, melanocytes and endocrine cells, and to diversemesenchymal' …

Head development in vertebrates involves a complex series of molecular and
morphogenetic events that generate a coordinated pattern of cartilages, bones and nerves …

The craniofacial region is assembled through the active migration of cells and the
rearrangement and sculpting of facial prominences and pharyngeal arches, which …

To investigate the influence of hindbrain segmentation on craniofacial patterning we have
studied the long term fate of neural crest (NC) subpopulations of individual rhom-bomeres …

Neural crest cells arise in the dorsal aspect of the neural tube and migrate extensively to
differentiate into a variety of neural and non-neural tissues. While interactions between …
