Cardiac neural crest is dispensable for outflow tract septation in Xenopus.
In vertebrate embryos, cardiac precursor cells of the primary heart field are specified in the lateral mesoderm. These cells converge at the ventral midline to form the linear heart tube, and give rise to the atria and the left ventricle. The right ventricle and the outflow tract are derived from an adjacent population of precursors known as the second heart field. In addition, the cardiac neur...
متن کاملCardiac outflow tract septation failure in Pax3-deficient embryos is due to p53-dependent regulation of migrating cardiac neural crest
During neural tube closure, Pax3 is required to inhibit p53-dependent apoptosis. Pax3 is also required for migration of cardiac neural crest (CNC) from the neural tube to the heart and septation of the primitive single cardiac outflow tract into the aorta and pulmonary arteries. Whether Pax3 is required for CNC migration and outflow tract septation by inhibiting p53-dependent apoptosis is not k...
متن کاملHIRA, a DiGeorge syndrome candidate gene, is required for cardiac outflow tract septation.
DiGeorge syndrome (DGS) is a congenital disease characterized by defects in organs and tissues that depend on contributions by cell populations derived from neural crest for proper development. A number of candidate genes that lie within the q11 region of chromosome 22 commonly deleted in DGS patients have been identified. Orthologues of the DGS candidate gene HIRA are expressed in the neural c...
متن کاملmiRNA-processing enzyme Dicer is necessary for cardiac outflow tract alignment and chamber septation.
MicroRNAs (miRNAs) have previously been implicated in a number of developmental processes, including development of the ventricular myocardium of the heart. To determine what, if any, additional roles miRNAs play in cardiogenesis, we deleted the miRNA-processing enzyme Dicer specifically in the developing murine heart. Embryos lacking cardiac Dicer lived longer than reported in previous studies...
متن کاملBmp4 signaling is required for outflow-tract septation and branchial-arch artery remodeling.
The Bmp4 signaling molecule is expressed in ventral splanchnic and branchial-arch mesoderm and outflow-tract (OFT) myocardium, suggesting a role for Bmp4 in OFT development. Inactivation of Bmp4 in the caudal branchial arch and splanchnic mesoderm and OFT myocardium by using a conditional null allele of Bmp4 and the Nkx2.5cre recombinase allele resulted in abnormal morphogenesis of branchial-ar...
