Figure Lengend Snippet: Fig. 1 | Single-cell and spatial transcriptomics of cardiac and ileum tissue of reovirus-infected neonatal mice. a, Experiment and analysis workflow. Four- day-old neonatal mice weighing 3 g per pup were infected (per os) with reovirus T1L. Neonatal mice infected with 1× PBS were used as mock controls. Ileum tissue (1 dpi and 4 dpi) and heart tissues (4 dpi, 7 dpi and 10 dpi) were assayed and used for scRNA-seq and spatial transcriptomics. b, UMAP plot of 31,684 single-cell transcriptomes from mock-infected and reovirus-infected hearts at 4 dpi, 7 dpi and 10 dpi (one animal per condition), clustered by gene expression and colored by cell type (left). UMAP plots showing cardiac cell type clusters across samples for the heart scRNA-seq data (right). c, 8,243 spatial transcriptomes of cardiac tissue sections from mock-infected and reovirus-infected mice at 4 dpi and 7 dpi (one animal per condition). H&E-stained image of reovirus-infected myocarditic
