Abstract
The influence of retinoic acid (RA) signaling on vertebrate development has a well-studied history. Cumulatively, we now understand that RA signaling has a conserved requirement early in development restricting cardiac progenitors within the anterior lateral plate mesoderm of vertebrate embryos. Moreover, genetic and pharmacological manipulations of RA signaling in vertebrate models have shown that proper heart development is achieved through the deployment of positive and negative feedback mechanisms, which maintain appropriate RA levels. In this brief review, we present a chronological overview of key work that has led to a current model of the critical role for early RA signaling in limiting the generation of cardiac progenitors within vertebrate embryos. Furthermore, we integrate the previous work in mice and our recent findings using zebrafish, which together show that RA signaling has remarkably conserved influences on the later-differentiating progenitor populations at the arterial and venous poles. We discuss how recognizing the significant conservation of RA signaling on the differentiation of these progenitor populations offers new perspectives and may impact future work dedicated to examining vertebrate heart development.

Abstract
Retinoic acid (RA) signaling is required to restrict heart size through limiting the posterior boundary of the vertebrate cardiac progenitor field within the anterior lateral plate mesoderm (ALPM). However, we still do not fully understand how different cardiac progenitor populations that contribute to the developing heart, including earlier-differentiating first heart field (FHF), later-differentiating second heart field (SHF), and neural crest-derived progenitors, are each affected in RA-deficient embryos. Here, we quantified the number of cardiac progenitors and differentiating cardiomyocytes (CMs) in RA-deficient zebrafish embryos. While Nkx2.5+ cells were increased overall in the nascent hearts of RA-deficient embryos, unexpectedly, we found that the major effect within this population was a significant expansion in the number of differentiating FHF CMs. In contrast to the expansion of the FHF, there was a progressive decrease in SHF progenitors at the arterial pole as the heart tube elongated. Temporal differentiation assays and immunostaining in RA-deficient embryos showed that the outflow tracts (OFTs) of the hearts were significantly smaller, containing fewer differentiated SHF-derived ventricular CMs and a complete absence of SHF-derived smooth muscle at later stages. At the venous pole of the heart, pacemaker cells of the sinoatrial node also failed to differentiate in RA-deficient embryos. Interestingly, genetic lineage tracing showed that the number of neural-crest derived CMs was not altered within the enlarged hearts of RA-deficient zebrafish embryos. Altogether, our data show that the enlarged hearts in RA-deficient zebrafish embryos are comprised of an expansion in earlier differentiating FHF-derived CMs coupled with a progressive depletion of the SHF, suggesting RA signaling determines the relative ratios of earlier- and later-differentiation cardiac progenitors within an expanded cardiac progenitor pool.

Abstract
Multiple syndromes share congenital heart and craniofacial muscle defects, indicating there is an intimate relationship between the adjacent cardiac and pharyngeal muscle (PM) progenitor fields. However, mechanisms that direct antagonistic lineage decisions of the cardiac and PM progenitors within the anterior mesoderm of vertebrates are not understood. Here, we identify that retinoic acid (RA) signaling directly promotes the expression of the transcription factor Nr2f1a within the anterior lateral plate mesoderm. Using zebrafish nr2f1a and nr2f2 mutants, we find that Nr2f1a and Nr2f2 have redundant requirements restricting ventricular cardiomyocyte (CM) number and promoting development of the posterior PMs. Cre-mediated genetic lineage tracing in nr2f1a; nr2f2 double mutants reveals that tcf21+ progenitor cells, which can give rise to ventricular CMs and PM, more frequently become ventricular CMs potentially at the expense of posterior PMs in nr2f1a; nr2f2 mutants. Our studies reveal insights into the molecular etiology that may underlie developmental syndromes that share heart, neck and facial defects as well as the phenotypic variability of congenital heart defects associated with NR2F mutations in humans. Many developmental syndromes include both congenital heart and craniofacial defects, necessitating a better understanding of the mechanisms underlying the correlation of these defects. During early vertebrate development, cardiac and pharyngeal muscle cells originate from adjacent, partially overlapping progenitor fields within the anterior mesoderm. However, signals that allocate the cells from the adjacent cardiac and pharyngeal muscle progenitor fields are not understood. Mutations in the gene NR2F2 are associated with variable types of congenital heart defects in humans. Our recent work demonstrates that zebrafish Nr2f1a is the functional equivalent to Nr2f2 in mammals and promotes atrial development. Here, we identify that zebrafish nr2f1a and nr2f2 have redundant requirements at earlier stages of development than nr2f1a alone to restrict the number of ventricular CMs in the heart and promote posterior pharyngeal muscle development. Therefore, we have identified an antagonistic mechanism that is necessary to generate the proper number of cardiac and pharyngeal muscle progenitors in vertebrates. These studies provide evidence to help explain the variability of congenital heart defects from NR2F2 mutations in humans and a novel molecular framework for understanding developmental syndromes with heart and craniofacial defects.

Abstract
Determination of appropriate chamber size is critical for normal vertebrate heart development. Although Nr2f transcription factors promote atrial maintenance and differentiation, how they determine atrial size remains unclear. Here, we demonstrate that zebrafish Nr2f1a is expressed in differentiating atrial cardiomyocytes. Zebrafish nr2f1a mutants have smaller atria due to a specific reduction in atrial cardiomyocyte (AC) number, suggesting it has similar requirements to Nr2f2 in mammals. Furthermore, the smaller atria in nr2f1a mutants are derived from distinct mechanisms that perturb AC differentiation at the chamber poles. At the venous pole, Nr2f1a enhances the rate of AC differentiation. Nr2f1a also establishes the atrial-atrioventricular canal (AVC) border through promoting the differentiation of mature ACs. Without Nr2f1a, AVC markers are expanded into the atrium, resulting in enlarged endocardial cushions (ECs). Inhibition of Bmp signaling can restore EC development, but not AC number, suggesting that Nr2f1a concomitantly coordinates atrial and AVC size through both Bmp-dependent and independent mechanisms. These findings provide insight into conserved functions of Nr2f proteins and the etiology of atrioventricular septal defects (AVSDs) associated with NR2F2 mutations in humans.
