Abstract
Over the past two decades, the development of chromosome conformation capture technologies has allowed to intensively probe the properties of genome folding in various cell types. High-throughput versions of these C-based assays (named Hi-C) have released the mapping of 3D chromosome folding for the entire genomes. Applied to mammalian preimplantation embryos, it has revealed a unique chromosome organization after fertilization when a new individual is being formed. However, the questions of whether specific structures could arise depending on their parental origins or of their transcriptional status remain open. Our method chapter is dedicated to the technical description on how applying scHi-C to mouse embryos at different stages of preimplantation development. This approach capitalized with the limited amount of material available at these developmental stages. It also provides new research avenues, such as the study of mutant embryos for further functional studies.
