Figure 4.

Clustering of expression of candidate genes involved in early embryonic development. Expression levels for 67 differentially expressed genes for the six samples were hierarchically clustered and shown in a heatmap. Level of expression was represented by color scale from green (low) to red (high), as indicated by a scale bar in the upper left corner. Dendrograms of distances were also shown for genes (left) and samples (top). Names of samples and genes were indicated on the bottom and right, respectively. For genes without annotation, probe set IDs were shown.
