A precise cellular and molecular cartography of the human embryo is essential to understanding of the mechanisms of organogenesis in normal and pathological conditions. We use tissue clearing and 3D imaging to build three-dimensional cellular maps of human embryos. We provide high-resolution 3D images of the developing human organs (muscles, skeleton, gonads, nervous system…). We also study and try to model human lung morphogenesis using AI and deep learning. We started to generate a comprehensive 3D cellular atlas of human head embryogenesis using VR-assisted image segmentation. These insights into human embryology have important implications for understanding developmental diseases, and advancing diagnostic and therapeutic strategies.
