AB  - In this paper, changes in a large-scale 3D structure of chromosomes during stem cell differentiation is studied. The polymer coarse-grained model of a human interphase chromosome is introduced which reproduces the experimental Hi-C contact maps in chromosomes 12, 17 for both embryonic stem and differentiated cells with high accuracy. Model based analysis of Hi-C data suggests a mechanism of establishment of preferential long-range chromosomal contacts and compartmentalization replacement during cell stem differentiation. The model provides the conceptual basis for integration of data on the dynamics of chromatin interactions, the 3D structure of chromosomes and gene expression during stem cell differentiation or reprogramming.
