Table 2

Representative genes from expression groups II and IV (see fig 2)

Group IV: expression increased during development			Group II: expression increased during differentiation
Name	Pub acc	Fold change	Name	Pub acc	Fold change
The columns on the left, group IV, indicate genes whose expression level is at least two-fold greater during embryonic development when compared to postnatal expression. The genes on the right hand side of the figure, group II, represent those genes whose expression is at least four-fold greater during postnatal development when compared to embryonic expression levels. Pub acc=the public accession number that corresponds to the Affymetrix probe set identifying the gene.
