Figure 1

The distribution of gene expression distance in tissue pairs: (A) for all tissues considered in this study, (B) for ectoderm tissues, (C) for endoderm tissues, and (D) for mesoderm tissues. ‘Inner’ represents the group of neighbor tissues, defined as tissues belong to the same super-node (red rectangle in Figure. 2). ‘Mid’ represents the group of tissue pairs from the segments of ectoderm, endoderm and mesoderm, while not in the same ‘inner’ group. ‘Outer’ represents the group of tissue pairs from different segments. Student's t-tests were performed on each data pairs of these groups from (A) to (D). (E) The gene expression divergence between amygdale and other tissues. The black curve represents the density of divergence between amygdale and prefrontal cortex. The green curve represents the density of the mean divergence of amygdale and other neural tissues. Red curve represents the mean divergence density between amygdale and other somatic tissues. KS test was performed to test the significance of the difference of these curves.
