(Submitter supplied) Ventricular chambers are essential for the rhythmic contraction and relaxation that occurs in every hearbeat throughout life. Congenital abnormalities in ventricular chamber formation cause severe human heart defects. How the early trabecular meshwork of myocardial fibres forms and subsequently develops into mature chambers is still poorly understood. Here we show that Notch signalling first connects chamber endocardium and myocardium to sustain trabeculation and later coordinates ventricular patterning and compaction with coronary vessel development to give rise to the mature chamber via a temporal sequence of ligand signalling determined by the glycosyltransferase Manic Fringe (Mfng). more...
