Figure 6From: Impact of animal strain on gene expression in a rat model of acute cardiac rejectionHierarchical clustering of the union of the probeset lists. Two-way hierarchical clustering of samples and differentially expressed probesets within (A) heart tissue from native and transplanted hearts from isogeneic (i) and allogeneic (a) transplants; and (B) peripheral blood mononuclear cells (PBMC) from untransplanted animals and isogeneic and allogeneic transplants. Rows represent microarray chips and columns represent probesets. Red indicates over-expression and green indicates under-expression. The dendrogram illustrates how the samples segregate into groups. For heart tissue, samples segregate mainly based on the presence and absence of rejection. For PBMC, samples segregate mainly based on strain irrespective of rejection or transplant status.Back to article page
