Abstract Background Pigs are important animals for agricultural and biomedical research, and improvement is needed for use of cIAP1 Ligand-Linker Conjugates 5 the assisted reproductive technologies. Determining underlying mechanisms of epigenetic reprogramming in the early stage of preimplantation embryos derived from in vitro fertilization (IVF), parthenogenesis, and androgenesis will not only contribute to assisted reproductive technologies of pigs but also will shed light into early human development. However, the reprogramming of three-dimensional architecture of chromatin in this process in pigs is usually poorly understood. cIAP1 Ligand-Linker Conjugates 5 Results We generate three-dimensional chromatin profiles for pig somatic cells, IVF, parthenogenesis, and androgenesis preimplantation embryos. We find that this chromosomes in the pig preimplantation embryos are enriched for superdomains, which are more rare in mice. However, p(s) curves, compartments, and topologically associated domains (TADs) are largely conserved in somatic cells and are gradually established during preimplantation embryogenesis in both mammals. In the uniparental pig embryos, the establishment of chromatin architecture is usually highly asynchronized at all levels from IVF embryos, and a remarkably strong decompartmentalization is usually observed during zygotic genome activation (ZGA). Finally, chromosomes originating from oocytes usually establish TADs faster than chromosomes originating from sperm, both before and during ZGA. Conclusions Our data spotlight a potential unique 3D chromatin pattern of enriched superdomains in pig preimplantation embryos, an unusual decompartmentalization process during ZGA in the uniparental embryos, and an asynchronized TAD reprogramming between maternal and paternal genomes, implying a severe dysregulation of ZGA in the uniparental embryos in pigs.
