Representative genes from expression groups I and III (see fig 2)

Group I genes			Group III genes
Name	Pub acc	Fold change	Name	Pub acc	Fold change
The genes represented in group I have a reduced expression pattern during the early embryonic stages of development (9.5 dpc), up during the proliferative stages of development (14.5 dpc-1 w) and down during the maturation period of lung development (2-4 w). roup I genes showed a two-fold or greater difference between the average of the 9.5 dpc and 14.5 dpc-1 w time point expression values. Group III genes shown have an expression pattern the opposite of the group I genes and a 1.5-fold or greater difference between the average of the 9.5 dpc and 14.5 dpc-1 w time points. Pub acc=the public accession number that corresponds to the Affymetrix probe set identifying the gene.
