  • The numbers in each box refer to the number of genes expressed in common by the two tissues that head the rows and columns that intersect at that box. The number of genes that each of these tissues does not express in common with the other can be determined by subtracting the value in the box from the total number of genes expressed by each of the tissues, as listed in Table 3.
