Methods that can map the influence of ligands on target genes across spatial niches are still necessary to improve our understanding of tissue microenvironments. Here, the authors develop Renoir, a method to infer ligand-target activities and map them to spatial niches in spatial transcriptomics data, with applications in fetal liver and hepatocellular carcinoma cells.
