Planar cell polarity protein, Vangl2, goes out of its way to shape the heart through a planar polarity-independent mechanism.

Why I highlight this work?
Shapes and patterns have fascinated biologists for centuries (1), and when that shape gets tied to the functionality of an organ, it’s no longer just a fascination. It becomes a vital part of biomedical relevance, as seen in the case of heart shaping.
In this preprint, Paul Palmquist-Gomes and colleagues have studied the shaping of the heart tube during development, and their observations spark two important points of debate. First, the role of the gene Vangl2 in epithelial morphogenesis as a regulator of exchange in cell neighbours. Second, the autonomy of an organ during development.
The observations made by the authors are fascinating and should be of particular interest to researchers working on morphogenesis, planar cell polarity and epithelial reorganisation.
Background
During development, the shaping of the heart tube is driven by a coordinated set of morphological events (2) simultaneously with the organogenesis of nearby organs like the neural tube. The morphological process of forming a tube from an epithelial sheet and shaping it is governed by asymmetric forces (3). One example is the asymmetric recruitment of the planar cell polarity protein, VANGL2, on the junctions (3, 4). This protein, in turn, recruits actin regulators and drives the process of forming and shaping a heart tube (5). A point mutant of Vangl2, called looptail, shows defects in the shaping of the heart but also in other tissues, raising the question of whether it is a secondary effect from nearby tissues (6). Also, Vangl2 seems to be indispensable for the morphogenesis of the heart (7).
Building on these studies, Palmquist-Gomes and colleagues have analysed the mechanism explaining how Vangl2 might regulate epithelial remodelling and how different parts of the heart contribute to this process.
Key Findings
Role of Vangl2 in shaping the heart. This study combines genetics and 3D imaging to first quantify the defects in heart shape in Vangl2 mutants. At embryonic day (E) 9.5, when heart looping is complete, the position of ventricles with respect to the left-right axis was perturbed in mutants. Also, the outflow tract (OFT) was shorter. The authors found that these defects became more severe at E10.5 and were also present in mutants where the neural tube had closed properly. This allowed them to infer the role of Vangl2 in heart looping independent of neural tube development.
Parts of heart contribute to different morphogenetic processes
The authors deleted Vangl2 specifically in the mesoderm that contains cardiac progenitors. The mutants showed a shorter OFT, but not the perturbed positioning of ventricles, suggesting an independent mechanism driving these two phenotypes. Interestingly, the deletion of Vangl2 from posterior cardiac precursors led to mutants with normal OFT but an abnormal ventricle position.
Analysing the activity pattern of Hoxb1Cre and Mesp1Cre, the authors argue that the caudal splanchnic mesoderm, which is specifically marked by Hoxb1Cre, anchors the heart tube and helps in maintaining it in the midline. This suggests that although the heart is a single organ, one aspect of morphogenesis could be influenced differently by different subsets of cells.
VANGL2 remodels epithelia by resolving cell-intercalation
The author team then dissected out the mechanism by first investigating the localisation of VANGL2 on cell junctions. Interestingly, they found that VANGL2 is low and symmetrical on cell-cell junctions but shows a higher accumulation on vertices where 4 or more cells meet. These rosette-like structures increased in Mesp1Cre-driven Vangl2 mutants. This suggests that the elongation of the OFT is driven by epithelial remodelling, where VANGL2 regulates the resolution of the multicellular rosettes. In the Hoxb1Cre-positive splanchnic mesoderm, VANGL2 and an actin regulator, SHROOM3, show similar occupancy on apical domains. Mutants for Shroom3 phenocopied the Hoxb1Cre-driven mutants of Vangl2, showing disorganisation of epithelia and an altered position of the ventricles without affecting OFT.

By integrating modern metabolic tools with genetic and epidemiological insights across model organisms, this event highlighted key mechanisms and identified open questions to advance the emerging field of developmental metabolism.
