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 neural crest cells and their local environments are required for the proper development of these tissues, little information is available about the molecular nature of the cell-cell interactions in cephalic neural crest development. Here we demonstrate that mice deficient for one type of endothelin receptor, ET(A), mimic the human conditions collectively termed CATCH 22 or velocardiofacial syndrome, which include severe craniofacial deformities and defects in the cardiovascular outflow tract. We show that ET(A) receptor mRNA is expressed by the neural crest-derived ectomesenchymal cells of pharyngeal arches and cardiac outflow tissues, whereas ET-1 ligand mRNA is expressed by arch epithelium, paraxial mesoderm-derived arch core and the arch vessel endothelium. This suggests that paracrine interaction between neural crest-derived cells and both ectoderm and mesoderm is essential in forming the skeleton and connective tissue of the head. Further, we find that pharyngeal arch expression of goosecoid is absent in ET(A) receptor-deficient mice, placing the transcription factor as one of the possible downstream signals triggered by activation of the ET(A) receptor. These observations define a novel genetic pathway for inductive communication between cephalic neural crest cells and their environmental counterparts.
