Interaction of canine carotid sinus and aortic arch baroreflexes in the control of total peripheral resistance.

abstract：RATIONALE:The development of the cardiac outflow tract (OFT) and great vessels is a complex process that involves coordinated regulation of multiple progenitor cell populations. Among these populations, neural crest cells make important contributions to OFT formation and aortic arch remodeling. Although numerous signal...
