Speaker | Loic Royer - Royer first studied engineering, math, and physics in his native France. He then obtained a master’s degree in artificial intelligence, specializing in cognitive robotics, followed by a Ph.D. in bioinformatics from the Dresden University of Technology in Germany. As a member of Gene Myers’ lab, first at HHMI’s Janelia Research Campus and then at the Max Planck Institute of Molecular Cell Biology and Genetics, he developed the first “self-driving” multi-view light-sheet microscope. Royer is fascinated by a seemingly simple but quite complex question: How do organisms develop from a single cell into a fully functional body with billions of self-organizing cells that form tissues and have different functions? He believes that solving this question will require expertise across computer science, advanced microscopy, and biology. To that end, Royer’s pluridisciplinary team designs and builds novel state-of-the-art light-sheet microscopes, develops deep learning-based image processing and analysis algorithms, and is using these technologies to build a time-resolved and multimodal atlas of vertebrate development, using zebrafish as model organisms. |

Elucidating the developmental processes of organisms requires a comprehensive understanding of cellular lineages in the spatial, temporal, and molecular domains. In this study, we introduce Zebrahub, a dynamic atlas of zebrafish embryonic development that integrates single-cell sequencing time course data with lineage reconstructions facilitated by light-sheet microscopy. This atlas offers high-resolution and in-depth molecular insights into zebrafish development, achieved through the sequencing of individual embryos across ten developmental stages, complemented by trajectory reconstructions. Zebrahub also incorporates an interactive tool to navigate the complex cellular flows and lineages derived from light-sheet microscopy data, enabling in-silico fate mapping experiments. We will also demonstrate recent results on reconstructing cellular histories by explicitly linking scRNAseq-derived transcriptomes with image-based lineages and spatial omics. Finally, to demonstrate the versatility of our multi-modal resource, we utilize Zebrahub to provide fresh insights into the pluripotency of Neuro-Mesodermal Progenitors (NMPs). Our publicly accessible web-based platform, Zebrahub, is a foundational resource for studying developmental processes at both transcriptional and spatiotemporal levels, providing researchers with an integrated approach to exploring and analyzing the complexities of cellular lineages during zebrafish embryogenesis.
