Temporal expression clustergram mapping of angiogenesis genes. Genes demonstrating a statistically significant increase in expression (p <.05, t-test) at one or more time points were clustered using an agglomerative hierarchical clustering algorithm. The similarity/dissimilarity metric, based on the Pearson correlation coefficient between two dimension profiles of qRT-PCR gene expression, identified 4 waves (i-iv) of gene expression. The dendrogram was based on average linkage clustering. The colored matrix display was encoded based on the value of the gene at the 5 time points; the relative dissimilarity index in the unshaded portion of the dendrogram was compressed for presentation purposes.
