Identification of a Tbx1/Tbx2/Tbx3 genetic pathway governing pharyngeal and arterial pole morphogenesis

The 22q11.2 deletion syndrome (22q11.2DS) is the most common microdeletion disorder and is characterized by abnormal development of the pharyngeal apparatus and heart. Cardiovascular malformations (CVMs) affecting the outflow tract (OFT) are frequently observed in 22q11.2DS and are among the most commonly occurring heart defects. The gene encoding T-box transcription factor 1...

Tbx2 and Tbx3 induce atrioventricular myocardial development and endocardial cushion formation

A key step in heart development is the coordinated development of the atrioventricular canal (AVC), the constriction between the atria and ventricles that electrically and physically separates the chambers, and the development of the atrioventricular valves that ensure unidirectional blood flow. Using knock-out and inducible overexpression mouse models, we provide evidence that...
