Figure Lengend Snippet: KC-hepatocyte crosstalk is altered in P0 KO Spi1 livers. (A) Bar plot showing the relative information flow of between WT Spi1 and KO Spi1 of inferred cell–cell communication using CellChat. (B) Comparison of the significant ligand–receptor pairs between WT Spi1 and KO Spi1 , which contribute to the signaling from KCs to the hepatocyte clusters. (C) Heatmap showing the relative importance of KC and hepatocyte clusters as sender, receiver, mediator and influencer, based on the computed four network centrality measures of IGF (top) and visfatin (bottom) signaling. (D) Box plot of variance stabilizing transformation-normalized Igf1 expression in hepatocytes and macrophages in WT Spi1 and KO Spi1 mice at P0. n =5 per genotype from 3 independent litters. Differential expression was tested using DESeq2 on raw counts. The whiskers represent the 5-95% percentile, the box extends from the 25th to 75th percentiles and the horizontal line represents the median. (E) Serum insulin levels measured by ELISA on WT Spi1 and KO Spi1 at P0. n =4-5 per genotype from 4 independent litters. Bar plot presented as mean±s.d. Unpaired Student's t -test. (F) Serum glucagon levels measured by ELISA on WT Spi1 and KO Spi1 at P0. n =6 per genotype from 3 independent litters. Bar plot presented as mean±s.d. Unpaired Student's t -test. (G) Enrichment analysis of downregulated phosphorylation sites showing the decreased and increased phosphorylation in KO Spi1 liver compared to WT Spi1 . n =4-6 per genotype from 5 independent litters.
