Welcome to Pig Matrix, the first systematically constructed 3D epigenomic reference atlas database for the pig (Sus scrofa). Derived from a unified large-scale experimental design, it provides matched multi-omics profiles across multiple developmental stages and diverse tissues or cell lines, serving as a high-quality benchmark resource for research in pig biology and human biomedicine. In addition to comprehensive retrieval, visualization, and data download of porcine epigenomic and 3D genome resources, Pig Matrix also integrates a suite of analysis tools to facilitate studies in xenotransplantation and translational medicine modeling.

Looking ahead, we plan to generate more comprehensive pig multi-omics datasets that cover a wider range of developmental stages and tissue or cell types, with a particular focus on embryonic and fetal periods. Building upon recent advances in single-cell multi-omics technologies, we will further expand our dataset portfolio to include modalities such as single-cell ATAC-seq and single-cell Hi-C. In parallel, we will develop and integrate additional specialized analytical tools aimed at linking pig genomic and epigenomic discoveries to translational research and applications in human health.
