Figure 1.

Relative comparison of the individual Genechip results. E18WT1 was used as a template for finding chips with a similar expression profile, using GeneSpring software. All samples were subjected to the correlation comparison. The result shows that the similarity of expression profiles to embryonic day (E)18 Nfia^+/+ is as follows: postnatal day (P)16 Nfia^+/+ < P16 Nfia^-/- < E18 Nfia^-/- < E18 Nfia^+/+. The E18 Nfia^+/+ expression profile exhibited greater correlation to the expression profile of P16 Nfia^-/- than to that for P16 Nfia^+/+. KO, knockout (Nfia^-/-); WT, wild-type (Nfia^+/+).
