This study developed a workflow using multi-scale and multi-disciplinary approaches to analyze the C-looping phase of chick heart development. The researchers provided the first 3D datasets of the C-looping heart, including heart images and segmented myocardial cell data. The results revealed differential spatiotemporal growth patterns at both cellular and tissue levels and identified potential candidates for the mechanism of C-looping.
We developed a workflow using multi-scale and multi-disciplinary experimental and computational approaches to analyze C-looping (the first phase of cardiac looping) of the chick across four developing hearts. We provide the first 3D datasets for the C-looping heart with cell to organism level information, including datasets of heart images and segmented myocardial cells within the heart. We used these datasets to investigate, as a proof-of-concept, the differential spatiotemporal patterns of growth at both the cellular and tissue levels, and demonstrate how geometrical changes of C-looping at the tissue level are linked to growth features at the cellular level. Our methodological pipeline provides preliminary results for qualitative and quantitative evidence of various cellular and tissue features as potential candidates regarding the mechanism of C-looping. This pipeline can be used and extended in future studies to include larger specimen samples for detailed analyses of, and potentially new insights into, cardiac C-looping.
