Inferring predictive genetic models and regulatory elements by deep learning of cross-species single-cell gene expression landscapes

Abstract: Despite extensive efforts to sequence different genomes, genetic models to interpret gene regulation and cell fate decisions are lacking for most species. Here, we performed whole-body single-cell transcriptomic analysis of zebrafish, Drosophila, and earthworm. We then mapped cell landscapes covering eight representative metazoan species to study gene regulation through evolution. With uniformly constructed cross-species datasets, we developed a deep learning-based strategy, Nvwa, to predict gene expression la… Show more

“…First, we performed a comparative analysis of gene regulation during development in seven species with varying evolutionary distances at single-cell resolution. Development atlases of four invertebrates and three vertebrates were involved, including Schmidtea mediterranea 12 , Caenorhabditis elegan 15 , Ciona intestinalis 16 , Hydra vulgaris 13 , Danio rerio 42 , Mus musculus 11 , and Homo sapiens 14 . More than 1,100,000 cells were collected and categorized into 665 cell type pairs for relatively differentiated states and undifferentiated states (Extended Data Fig.…”
