960-Spatiotemporal Maps of Whole Mouse Embryos

Researchers have developed a comprehensive spatial transcriptomic atlas of the mouse embryo during the critical stages of organogenesis. By utilizing Slide-seq technology, the team generated high-resolution maps that preserve the original tissue architecture, which is often lost in traditional single-cell methods. To navigate this vast dataset, they created sc3D, a computational tool that reconstructs individual tissue slices into three-dimensional virtual embryos for detailed gene expression analysis. This framework enabled the discovery of previously unmapped genes and the visualization of developmental trajectories within the neural tube and brain. Additionally, the study applied these tools to investigate Tbx6 mutant embryos, revealing the complex molecular identities of abnormal physical structures. Ultimately, this work provides a powerful open-access resource for exploring the spatiotemporal regulation of mammalian development and genetic mutations.References:Sampath Kumar A, Tian L, Bolondi A, et al.
