Overview of the restricted expression patterns. For unique genes in each cluster, we summarized the array profiles, diversity of annotation terms (as an anatogram), and number of total and core genes and show two to four embryo images. Whenever possible, genes with previously uncharacterized expression patterns were selected. Array plots show the distribution of scaled intensity scores: the blue line indicates the median value while the gray box gives the inter-quartile range. The most relevant annotation terms in each anatogram are labeled.
