Genomic imprinting, manifested as monoallelic expression of genes according to parental origin, is linked to mammalian placentation and human diseases. The authors integrate single-nucleus transcriptomes and whole-genome variations to create a cell type-specific genomic imprinting atlas of pig placenta, highlighting the role of cell-cell communication in parent-of-origin effects on gene expression.
