Abstract
Spatial genome organization in the cell nucleus plays a crucial role in the control of genome functions. Our knowledge about spatial genome organization is relying on the advances in gene imaging technologies and the biochemical approaches based on the spatial dependent ligation of the genomic regions. Fluorescent in situ hybridization using specific fluorescent DNA and RNA probes in cells and tissues with the spatially preserved nuclear and genome architecture (3D-FISH) provides a powerful tool for the further advancement of our knowledge about genome structure and functions. Here we describe the 3D-FISH protocols allowing for such an analysis in mammalian tissue in situ including in the skin. These protocols include DNA probe amplification and labeling; tissue fixation; preservation and preparation for hybridization; hybridization of the DNA probes with genomic DNA in the tissue; and post-hybridization tissue sample processing.Entities:
