Expression of the BMP Receptor Alk3 in the Second Heart Field Is Essential for Development of the Dorsal Mesenchymal Protrusion and Atrioventricular Septation
13 Apr 2013
Abstract excerpt
RATIONALE: The dorsal mesenchymal protrusion (DMP) is a prong of mesenchyme derived from the second heart field (SHF) located at the venous pole of the developing heart. Recent studies have shown that perturbation of its development is associated with the pathogenesis of atrioventricular (AV) septal defect. Although the importance of the DMP to AV septation is now established, the molecular and cellular...
