Figure 4From: Construction of a cDNA library for miniature pig mandibular deciduous molarsGenes from the four time periods were compared with each other. The differentially expressed genes from E35 vs E45, E35 vs E50, E35 vs E60, E45 vs E50, E45 vs E60, and E50 vs E60 were compared. (A) The number of up-regulated and down-regulated genes in each group is shown in the histogram. (B) The hierarchical clustering analysis of differentially expressed transcripts at different developmental stages.Back to article page
