Cell autonomous requirement for PDGFRalpha in populations of cranial and cardiac neural crest cells.

Abstract excerpt

Cardiac and cephalic neural crest cells (NCCs) are essential components of the craniofacial and aortic arch mesenchyme. Genetic disruption of the platelet-derived growth factor receptor alpha (PDGFRalpha) results in defects in multiple tissues in the mouse, including neural crest derivatives contributing to the frontonasal process and the aortic arch. Using chimeric analysis, we show that loss of the receptor in...
