Figure 4From: Exploring nervous system transcriptomes during embryogenesis and metamorphosis in Xenopus tropicalis using EST analysisDigital expression profiles of X. laevis transcripts differentially expressed at metamorphosis. Using the same representation as in Fig. 3 three clusters are depicted that are associated with differential expression at metamorphosis (top cluster), tadpole stage (middle) and in the forming limb (down).Back to article page
