We developed Tethered Conformation Capture (TCC), a method for genome-wide mapping of chromatin interactions. By implementing solid-phase ligation, TCC substantially enhanced the signal-to-noise ratio and thus, enabled a detailed analysis of inter-chromosomal interactions. We identified a group of regions in each chromosome that predominantly mediate inter-chromosomal interactions. These regions are marked by high transcriptional activity, suggesting that their interactions are mediated by transcription factories. Each of these regions interacts with numerous other such regions throughout the genome in an indiscriminate fashion, partly driven by the accessibility of the partners. Therefore, it is likely that a different combination of interactions is present in different cells. Accommodating this variability, we developed a computational method to translate the TCC data into physical chromatin contacts in a population of three-dimensional genome structures. Statistical analysis of the resulting population demonstrates that the indiscriminate properties of inter-chromosomal interactions is consistent with the well-known architectural features of the human genome.
