Figure 3From: Measuring similarities between gene expression profiles through new data transformationsAverage expression profiles for the 153 SAGE tags. These 153 tags fall into 5 clusters: 125 of these genes are developmental genes and can be further categorized into four groups (Early I, Early II, Late I and Late II) by their expressions at different developmental stages; the other 28 genes are not relevant to the mouse retina development.Back to article page
