Spatial genomics tool maps DNA interactions, preserving cell locations

• A spatial genomics tool has been developed to map long-range DNA interactions.
• The tool preserves the locations of cells within tissues, aiding in understanding DNA's 3D organization.
• Previously, scientists had limited understanding of how DNA's 3D organization is regulated.
• DNA is packaged with proteins into chromatin, which is folded into complex 3D structures.
• This tool provides new insights into the regulation and changes of DNA's 3D organization over time.
