摘要：SummaryWe 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.Graphical abstractDisplay OmittedHighlights•A hybrid experimental-computational pipeline to study heart C-looping•A multi-disciplinary, multi-scale study of growth-related development in C-looping•Insights for future studies to address differential growth during C-looping•Potential to extend the pipeline for detailed analysis of mechanisms of C-loopingBiological sciences; Developmental biology; Biological sciences research methodologies
